User questions & answers

Question:	Do these have a NRR rating
Answer:	They provide 30 dB passive noise attenuation
Question:	Does anyone know the impedance of these headphones
Answer:	Don't know. Most headphones like this are of such an impedance that they work plugged into the headphone jacks of stereo and radio gear. The Koss QZ-99 plays at what seems to be a normal sound level appropriate to the volume setting. I use mine for amateur radio, but I've also listened to my stereo gear with good results. Sound quality is excellent. The only place where impedance is important is for crystal radios and old radio gear that requires very high impedance. That's not the situation here.
Question:	I mostly listen to podcasts, mainly want to reduce ambient noise in a huge open office. Recommend
Answer:	Hey Climbing - they will definiteky reduce noise. I actually use them to listen to podcasts while mowing the lawn. They are a little bulky because they cover the whole ear. If you don't mind that then I would recommend them.
Question:	Is the sound quality better or worse than 10$ ear buds
Answer:	Short answer, MUCH better than ear buds (esp at $10). Here is why (also why ear buds will NEVER sound better than over ear.) 1) isolation - over the ear headphones automatically reduce ambient noise (not just block it out at high volume), allowing you to hear the music more clearly. 2) size of speakers - I worked in the speaker industry for over ten years, there are some excellent sounding smaller speakers (bose, for example) but for the most part, size matters. It is a physical property of sound that deep, base notes need a large cone to produce a low frequency. A lot more science involved than that but that's the punchline, you can't get good base from small speakers.The smaller the speaker the less of the bottom end you will get so inherently, in ear headphones (with smaller speakers) will never be able to produce the base notes that over ears can. There are a lot of base boosting software and crossovers that try to compensate this but never can pull it off like natural reproduction.

User questions & answers

Question:	How does the mic work
Answer:	Our Hammocks is Ideal for Backpacking and is made of good quality. The Double hammock alone weights 1.24 lbs and the Single weight is .89 lbs. The Tree straps are designed for beginners and easy use. Because of the extra loops the tree straps weights .47 lbs and the heavy duty Carabiners weights 62.6 grams. Total kit weight for the double is 2.57 lbs and the single is 2.12 lbs. If you want a lighter load you could upgrade the straps and the Carbinear. For the listed price this is still a good buy even if you decide to upgrade the accessories for a lighter load.
Question:	Can you mute the mic
Answer:	Two adults would Not be as comfortable in a single Hammock. A double size would be ideal. Both the single and double holds 661 pounds. My friends husband and wife shared a single during a camping trip they only sat in it together. If you truly want to relax go for a double for two Adults
Question:	how long is the cord
Answer:	The straps that comes in this kit has slightly more than 19 feet of use. The hammock length for the double is about 9.84 ft. The single is about 9 that gives you a total area of Play of near 28 ft single -almost 30 ft XL, double unit Keep this in mind! I truly hope all hammock users read this. Its not about my product its about camping, hiking, even at your loved ones home..when I first started to use portable hammocks I forget that tree trunks range. They could be small or HUGH! . I live in California and I tested these units in Jamaica, California ,Oregon. and Texas. Oregon and California trees could have some really Hugh TRUNKS. Please keep that in mind for any hammock and straps you decide to purchase not just my families product. I tend to use a 1- 3 ft trunk so if you have 20 feet a part and your tree is 3 feet would be -3 feet of that usage. Outdoors family to any family, gal or guy. I hope this answer helps you decide what outdoor gear you want. Enjoy the outdoors!
Question:	Are these sound isolating at all
Answer:	It would take some creative rigging, but it might be possible.

User questions & answers

Question:	Can I use these in my Skype sessions
Answer:	No volume control nor a mute button.
Question:	Will these headphones fit into my usb port on my computer or my ipod
Answer:	I only have the 3.5 jack set, so I can't tell you anything about the USB version... but if you need a budget headset, this gets the job done. Koss is very experienced at making headphones, so the audio quality on the phones themselves is fine. The mic quality is a little suspect, though. When voice chatting, I've been told that there's a lot of interference and it sounds like it's low quality. They can still understand what I'm saying for the most part, though.
Question:	Does this have a removable cable, or is the cord permanently attached to the headphones
Answer:	The USB version is https://www.amazon.com/dp/B00CK9BL4S/_encoding=UTF8?coliid=I24DNAZNHZHB3X&colid=2C7E18H31CYA9
Question:	Do they completely cover the ear
Answer:	I wear glasses and I do wear the 'phones for hours. They are very comfortable- you really don't notice any pressure on your glasses.

User questions & answers

Question:	How long is the Cord
Answer:	They do, but depending on the model, shipping can be prohibitive. If you had a pair any cheaper than the porta pro's, it would not be worth it to send in for warranty. They charge $9 for return shipping and handling, plus whatever it costs you to ship the item to koss. You're looking at roughly $18 to ship this $40 pair of headphones in for warranty. Something like the sportapro's or the ktx1pro's would not be worth sending in.
Question:	Does this have a microphone
Answer:	They go over top of the head, but they are very lightweight and comfortable. I switched to these from some sony behind the head phones... I dont mind the change at all.
Question:	Does anyone knows if there is any replacement for the cushion?. Mine got wearout
Answer:	No. Theses sound great, but the ear cushions are open foam. I wear these while walking so I can still hear cars, dogs, etc., that might be coming up behind me. Noise canceling headphones would be best for use on a plane where the environment is noisy and you don't have to listen for potential hazards.

User questions & answers

Question:	Can I use to make phone calls on my android phone
Answer:	Great mic for making calls with Android. I know that people with "i" devices are having issues, but calling and using the button functions work great with my LG G6.
Question:	So I can answer phone calls with this if it's connected to my phone correct
Answer:	Yes, and it works great. I have read that some people have problems using these with "i" devices, but they work great with my Android (LG G6). If you get a call just push the button to answer and again to hang up. For music you can use this to pause (single tap) or go to next track (2 clicks). I get no complaints from callers regarding the quality of the microphone.
Question:	Will these work with PS4 plugged into the controller with the mic
Answer:	My son has been using it for that purpose so I guess it would work.
Question:	Do these have the same drivers as the Portapro
Answer:	I was told by the customer service department at Koss that these are indeed the exact same drivers as the PortaPro and SportaPro. Interestingly, that same person told me that the best driver they make are the ones in the KTXPro1, which is identical to these but with a titanium coated diaphragm for added stiffness. From what I can hear, they all sound identical.
