User questions & answers

Question:	Do these suppress engine noise
Answer:	They suppress all noise by virtue of the seal around the ear, but they won't block it out because they're not technically noise canceling (no active noise suppression). They also do better with high frequency noise and aren't as good in low frequency where much engine noise lies, which is true of all things that only passively block noise eg ear plugs. So the answer is yes to a limited degree, but it won't be a complete suppression by any means and more in the high frequencies. I've found the combo of these with earplugs to be very effective for airplane noise.
Question:	Is the cord detachable? The description says it is detachable, answers here say otherwise
Answer:	The cord is not detachable but it is replaceable.If you're handy with a soldering iron you can however easily add a 3.5mm headphone jack to use a removable cable.
Question:	How is the sound leakage? l need portable headphones to use in the bus, library, and such. I don't want to bother people around me
Answer:	There is "sound leakage". At the moment, I have them hooked up to my computer. No special amplification, just on-board Realtek. At 75-100% volume, I can slightly hear them over ambient noise (such as my heater, which is kind of loud) while standing about ten feet away. I don't know if everyone else that answered this question listens to their music at low volume, or if their headphones have some insulation that mine doesn't but in my experience, there is plenty of "sound leakage". Also, you could actually use these as speakers while you're not wearing them. They wouldn't be loud enough to entertain anyone, but you could still listen to something while they sit on your desk.
Question:	How durable are they in cold weather
Answer:	I’m a professional location sound mixer in Alaska. I’ve had these headphones out in -50 F weather for 12 hour shoots. These headphones can withstand the cold

User questions & answers

Question:	Can any recommend an amp for these? i was thinking of getting the objective 2 but if anyone else has a better one please tell me. p.s. i'm on a budget
Answer:	I powered the HD599s with my LG-G4 smartphone, an Acer Chromebook R-13 (excellent headphone section for a laptop), a Schiit Modi 2 Uber/ Vali 2 (Genalex Gold Lion 6922 tube) stack that I use at work (I also used a Schiit Magni 2 Uber with the Magni 2 Uber), and a Schiit Bifrost Multibit/Valhalla 2 (Genalex Gold Lion 6922 tubes)stack I have at home (I also used a Schiit Asgard 2 with the Bifrost). I did/do not apply any equalization or effects when I listen. Like all the higher end Sennheiser headphones, the HD599s improved noticeably as the driving components improved. After a lot of listening to the 598s and 599s I concluded that they both sounded best when run through my Bifrost/Asgard 2 stack (The Modi 2U/ Magni 2U pairing was also excellent), so this is how I listened when doing my analysis. Like most lower impedance headphones, they both seem to prefer solid state amps to OTL tube amps, but they did pair well with the Vali 2 (a hybrid tube amp) as well. I know the O2 is a brighter amp (and solid state) and would probably pair quite we with these.
Question:	How is the bass on these headphones? Does it effect the mids/highs at all
Answer:	While these aren't "bass head" headphones, they have noticeably more bass than their predecessor the HD 598s. I always found the HD 598s to be a little "bass light", where the HD 599s have a much richer sound. The HD 599's are more musical where the HD 598s are more analytical. Depending on the track and your listening level there may be some noticeable intermodulation distortion where the bass frequencies will distort the mids and highs. On Deadmau5's new track "Let Go" the effect is very noticeable when you turn them up (and not all that loud). Playing the same track on my HD 600s, HD 650s, and HD 700s does NOT result in this distortion. It isn't that the bass is distorting, it just interferes with the mids and highs. These HD 599s are my daily driver (at work) and I REALLY like them. They are a far more versatile than the HD 598s, they sound fantastic, and I don't regret the purchase at all. At work I run them on a Schiit Modi 2 Uber/Magni 2 Uber stack and the pairing with the HD 599s is excellent. The highs are also better on the HD 599s than the HD 598s (which struggled with "Sh" and "F" sounds).
Question:	Can you use these on a phone
Answer:	I do So everyday at work. No external DAC or Preamp, and its just an iPhone 6.
Question:	How do these compare to the 598s
Answer:	I think the sound is tighter, the base is slightly more pronounced, again, tighter with some snap but not boom box silliness. The sound is more focused as if you were close to the stage and not several rows back. The soundstage or separation is very close to the 98 but not that noticeable unless you're very observant. The build is better, and these phones will not have to be handled like rice paper or egg shells. Overall, just a better headphone, really. It is said, by many, the 599 shares some values present in the Senn 600 with its clinical clarity and separation of instruments present. The highs are well rounded, not sharp or shrill. The midrange presence is very solid, and not released. These are not V sounding phones like your M50 Audio Technica. To me, those phones are offensive. The V sound is pronounced base, kind of extreme, and ditto for the offensive treble while the mids are not really projected. The Senn is the opposite, a very balanced headphone in all respects, with wonderful separation, clarity, and build. It is a great all around jack of all trades headphone. That is, TV movies sound really good with these and music, well, I like them better for the focus and presence compared to the 598. Hope this helps. As far as the 598, those are cheaper if you buy the black model. And the 558 sounds a lot like them, and even cheaper if money is an issue. You may also, for a few dollars more, look into the Shure 1440 headphones. They are within affordable range, just as good as the 599 in every way, but do not have that dark and sometimes veiled sound as the Senn does.

User questions & answers

Question:	do the headphones cover the whole ear or do they rest on it
Answer:	They rest on your ears. They do not completely go around them.
Question:	I bought these to plug into the headphone jack on my laptop. The plug looks way too big. Is there an adapter I can buy or should I return the headphones
Answer:	Are you sure you can't twist it off? A while back I bought a pair of Sony headphones that had a 1/4 inch jack and you could just twist or pull out the converter to reveal a 3.5mm. I use headphones for guitar practice so I keep the 1/4 inch on.
Question:	does it fit a computer
Answer:	It fits the audio jack on my computer just fine! :) It's just a standard headphone plug, so as long as you have a place to plug in a set of headphones, you should be good!
Question:	How is the volume on this? I have a hearing problem and sounds are usually too low for me to enjoy
Answer:	You want to look at dB SPL output...I saw a spec sheet saying that these produce 108 dB SPL compared to the next model up which produces 115 which would be dangerous as 112 dB SPL is the level at which permanent hearing damage occurs. 108 dB SPL (sound pressure level, or how we hear volume) should be enough as it is 5 times the SPL of ambient room noise. (every increase of 6 dB doubles the intensity) Electronic specs really have to do with matching the amplifier to the speaker (in this case the small ones in the headphones) hope this helps some. btw I am not Kevin I'm using his login now.

User questions & answers

Question:	Do they work (play music over Bluetooth) while charging
Answer:	If the tire is 700x25, these tubes should fit. Make sure you inflate your tires to the recommended PSI. The word "race" is irrelevant...the tube and tire dimensions are what matter, along with proper inflation.
Question:	How long is the cord
Answer:	Check YouTube on how to install a tire. Yes, there is slack (assuming the slack is the circumference). You need to partially inflate the tube, put the stem through, then begin working the tire on. You can let more air out if you need room to get the sidewall in. It's not the easiest task, but it's definitely doable by yourself.
Question:	Does this install in the helmet or put them on your ears, then the helmet over
Answer:	They are smooth and hard to get my pump to stay on. I hate them.
Question:	Can anyone tell me how long they take to charge fully? Does the light change colors when it is fully charged
Answer:	I’m guessing you mean 60mm deep dish ? If so then the 80mm valve should be sufficient for your needs. You could also buy a valve extender that you move from tube to tube as you require

User questions & answers

Question:	Hello, differences between the hd569 and the hd579? What of these is better
Answer:	Hello, It all depends on what you are looking for, HD 569 is a closed type headphone, it isolates you from your environment and vice-versa (ie: the sound is contained within the headphones). This is perfect for critical listening or a situation where you do not want to disturb/be disturbed. While HD 579 is an open type, it means that it avoids adverse resonating effects in the earcup thus offering best possible sound reproduction with the utmost in transparency. For sound quality, HD 569 is better, it does have strong and juicier bass.
Question:	do they have batteries
Answer:	They do not need batteries.
Question:	Is the headband replaceable on the 569? Also, what replacement ear pads are compatible with this model
Answer:	Because the wire runs from the left ear cup through the band to the right, I doubt you could replace the headband without replacing the whole unit. Fortunately the headband is highly flexible and very durable; so you may not need to replace it in the life of the headphones. As far as the ear pads themselves, I believe they are the same as the rest of the 500 series.
Question:	Hi, differences between 598cs and 569? also I'd like to know if it is possible to use v-moda boompro cable or similar instead of provided. thanks
Answer:	I have both and the sound is IDENTICAL. The 598cs is a special Amazon Only model. The builds are a bit different, and I do find the HD-569s a tad more comfortable (in the headband). Again, absolutely NO DIFFERENCE in the sound.

User questions & answers

Question:	How many stages of height adjustment is available on each side of the speakers ? (Is it symmetrical on both sides
Answer:	Amazon seems to be cross post this on different aftershokz products. The aftershokz aeroplex definitely will not fit a large head. My head is 7 1/4 and the bone conduction part wants to rest in the ear canal where an earbud would go instead of in front of the ear on the cheekbone where its supposed to be.
Question:	Best affordable dac& combo or seperate (under
Answer:	SOLUTION TO LOUD BEEP iPhone: Click Settings (that gear thing), then ... Click Sounds & Haptics, then ... Click Headphone Safety Now turn on Reduce Loud Sounds Move slider and experiment. I moved slider to “85 decibels as loud as heavy traffic” and this was perfect for me. Ok to thumbs up and move this to top Android has the same setting but different menu system, so look for it. I have Titanium, Aeropex, OpenComm and iPhone Bluetooth buds, this works for all.

Question:	If I pair these with a 19.95 Sony Walkman tape player from ebay will that be ironic enough to get me in with the hipsters
Answer:	There is no way for and end user to change the beep volume. Supposedly, Aftershockz is aware of this. Their "R & D department is "working on this" and a "product of lower beep sound" will be "introduced to the production line" and "the volume of the sound will drop by 3dB". (Source: A contact us / support request email exchange with Aftershockz in JAN 2021. No indication of which model or when this improvement will be introduced, but I am hoping soon and that they tell us when it happens). If I remember correctly, the beeps on my older Trekz Titanium were a lot quieter. The loudness of beeps on my recently purchased (Jan 2021) Aeropex Mini is very jarring and almost painful if I am wearing ear plugs or in a quiet environment. I find that loud beeps aren't as bad if I am not wearing ear plugs, but definitely annoying and a bit uncomfortable. In my opinion, this is a SERIOUSLY BAD DESIGN decision by Aftershockz. This has CHANGED my view of the Aeropex / Aeropex Mini from a really AMAZING, NEARLY PERFECT product, to something that I am SERIOUSLY CONSIDERING RETURNING. (Since language settings can be changed by the end user, I think Aftershockz should seriously consider a programming a setting where you can mute these beeps for those sensitive to loud or abrupt sounds.) (NOTE: I tried lowering & muting my ring tone and adjusting max volume settings on my phone per other commenter's suggestions, but this has not had any effect on the loudness of the headset button beeps. I am not using an iPhone though.)

Sennheiser HD 800 S

The audiophile headphones all others are measured against, the HD 800 S doesn’t just raise the ceiling for critical listening—it catapults right through it. The HD 800 S is assembled at Sennheiser's state-of-the-art facility in Germany so you can explore your entire music collection from the inside out.

The Exploration of Sound

The HD 800 S demonstrates over seven decades of audio expertise, redefining the critical listening experience. Sennheiser's goal was to provide acoustics so immersive that you the lines between playback and reality were erased. The signature sound of the HD 800 S is possible because of the synergy of every world-class component.

Around-the-Ear

Luxuriously soft earpads rest around the ear for long-term comfort.

Open Earcups

Experience the breathtaking sound of a vented earcup that lets soundwaves expand naturally.

Wired

Comes with cables for connecting to singled ended 1/4-inch (6.3mm) and balanced 4.4mm Pentaconn outputs such as headphone amplifiers, A/V receivers, audio interfaces and more.

It Has A Ring To It

The heart of the HD 800 S and its striking sound is the 56mm Ring Radiator transducer. It leverages the air displacement of a large speaker diaphragm without losing the rigidity of a smaller one. The result is hyper fast response for superb detail across the entire frequency range. The headphone’s vibration damping chassis and inert headband ensure that what you put into the HD 800 S is precisely what you will get out of it, too.

Each transducer is manufactured, tested, and measured to the tightest tolerance for the most dependable performance out of the box. Even the 40mm voice coil is wound in-house to ensure the shape and consistency is held to the highest standard. Each HD 800 S includes the frequency response plot unique to those perfectly matched transducers, sparing no resource to help you retrieve the most critical details from every corner of your music collection.

Behind the Mask

Achieving acoustics that are true to the source also requires management of compounding frequency clusters that produce undesirable masking effects. Sennheiser integrated a patented frequency absorber to reduce resonances that hide extraordinary musical details in plain sight. Further, the transducer system is mounted in a vibration damping chassis using aerospace-grade materials. As a result the problematic energy peaks of lower frequencies are controlled to unveil the purity your hi-fi setup is capable of.

Let’s take a look at the specifications...

User questions & answers

Question:	Will i get a good frequency response from using these on a onkyo a/v receiver without any eq? my use is to route my tv audio via toslink to my onkyo
Answer:	Microphone is pretty good. Callers on the other end of the line have been able to hear me with out any issues.
Question:	Do i need a amp for these headphones
Answer:	It says it is around-ear, however, I had to send these back because they were very obviously On-Ear headphones. I have small ears and these hardly touch my head, 95% of the pads are on my ears just like an on-ear headphone. I have the HD598's and they are very large - they don't touch my ears at all. I've had some around-ear headphones that are on the small size and barely clip the top or the lobes - This is not what's happening with these HD 4.40 BT - They are literally just sitting completely on my ears like an on-ear model would. I even had to check the box to make sure they didn't send me an on-ear model - but nope - the box says 'Around-Ear'. Definitely not. Sent these back and just grabbed a second pair of HD598's, but this time the closed-back version and I'm much happier. You can't go wrong with the HD598's.
Question:	Can I use these for voice recording
Answer:	it is a problem with a lot of bluetooth headphones and iphones. Here is an apple discussion about it https://discussions.apple.com/thread/7532276?start=0&tstart=0
Question:	How do 300 sound compared to hd
Answer:	The opening itself is 2.4" going across vertically and 1.47" hoizontally. The cup's thickness is 0.8"

HD 300 PRO Professional monitoring headset series

Capable of locating everything. Reproducing every detail. Staying precise when it comes to both fine subtleties and maximum sound pressure levels: the newly developed acoustic system in the HD 300 PRO enables neutral, delicate sound reproduction. The high level of wearing comfort and efficient ambient noise attenuation ensure that nothing will disrupt your concentration.

Did you know? The HD 300 PRO headphones are manufactured in Ireland.

Viscoelastic Earpads

The design represents a smart combination of wearing comfort and ambient noise attenuation. To achieve this, we have designed the acoustic unit to be more isolated than a monitoring set has ever been. Even after sessions lasting several hours, you will detect only its sound – not its weight.

Viscoelastic earpads and specially sealed acoustic elements provide efficient shielding against external noise. A high level of wearing comfort is ensured by optimum pressure distribution and a recess for the fontanelle. Structure borne noise is filtered out through a coiled cable directly by the earpiece.

Active Gard: Smart protection

Available on the HD 300 PROtect and HMD 300-XQ-2 models, Active Gard technology does not simply switch off at peak levels above 110 dB but reduces signals that are too loud down to a safe level. Other design elements also protect the user’s concentration. For example, the maximum shielding of ambient noise and a sound pattern that is everything you could want when it comes to intelligibility, differentiation or resolution. The ergonomic design guarantees that, even after hours of work, only one thing ‘carries weight’: the sound.

BMD 404 microphone

The acoustic elements of the HMD 300 PRO-XQ-2 have been systematically adjusted for maximum intelligibility, even in demanding environments. This is ensured by highly sensitive transducers with precision diaphragms, which reproduce the input signals in a crystal clear manner, free from distortion.

For the clear transmission of speech, a supercardioid, dynamic microphone is used. It is guaranteed to generate a detailed sound which can be relied on even in the loudest of environments. Includes wind and pop screen.

Cables Included!

Due to our established modular concept the cables of the cable 26-II series are compatible

• HD 300 PRO // HD 300 PROtect include a 1.5 meter cable with 3.5mm jack and 1/4" adapter jack
• HMD 300-XQ-2 include a straight copper cable with coiled segment to eliminate structure born noise. Reinforced with Aramid for improved durability, and softer shield for greater flexibility. XLR-3 connector and 1/4” jack plug with gold plated contacts

Professionally precise

The acoustics of the HD 300 PRO series are systematically tailored to the requirements of professional use. Its linear frequency response provides a neutral, high-resolution sound. With its highly sensitive transducers and precision diaphragms, the HD 300 PRO series achieves a phenomenal depth of detail which it reproduces – even at maximum volumes – in a crystal clear manner without distortions.

Measuring the truth

Distortion, wobbling motions and partial vibrations of the diaphragm have been reduced to a minimum. Together with highly sensitive transducers, this construction guarantees powerful and distortion-free reproduction even at high sound pressure levels. Not to mention the recalculated air volumes in front of the ear. The HD 300 PRO series gives the sound a remarkably natural, three-dimensional quality.

As meticulous as you

Capable of locating everything. Reproducing every detail. Staying precise when it comes to both fine subtleties and maximum sound pressure levels: the newly developed acoustic system in the HD 300 PRO series enables neutral, delicate sound reproduction. The high level of wearing comfort and efficient ambient noise attenuation ensure that nothing will disrupt your concentration.
