Notice:

When using B4-X with your cellphone, if you heard some "zhi ~ zhi" noise in your headphone. Probably it is the inteference from your cellphone such like WIFI or 4G signal, which intefers the tube and cause noise. That's normal. Because there are microphone effect with all tubes. To avoid it, please keep your cellphone far away from B4-X.



Q&A:

Q: Tried different source and headphones, but the right channel still has static.

A: Maybe the tube has a poor contact after long shipping process, open the chasis and adjust the screw near the tube while listening (if you cannot find it, contact us and we will give you a photo with marks to help you). Maybe the tube is broken, you can buy a 5899 tube in local shops. And we will refund you the cost.

Q: It broke just now four loud pops and it's doesn't work now.

A: Mainly because the battery is run out of power. Please charge it. If no help, please contact us.

Q: The Amp has a lot of electronic feedback/interference when a cellphone is nearby. It creates popping in the headphones.

A: Vacuum tubes are easy to be interfered by devices that can transfer siganl like cellphones, routers. Please keep the amp away from them.

Q: It cannot be charged, something is loose inside the charger.

A: Maybe the charger is broken. Contact us to get a new one please.

• The difference between B4 and B4-X: ① B4-X is a dual-mono balanced version. Its left and right channel are amplified by independent components, and power supply, tubes, and op amp are all independent and symmetric. So the degree of sound separation is higher than B4.
• ② B4-X adopts 2 groups of independent power supply(+12V and -12V) for 2 op amps, less mutual effects and can drive 300Ω headphones. ③ The circuit adopts dual op amp parallel output, with higher output power. ④ B4-X has 3.5mm and 2.5mm 2 kinds of output interface, suitable for most of balanced and standard headphones.
• Mini size and unique design: built-in tube makes you have a tube amplifier which can be held by one hand, convenient to carry and can enjoy HiFi music everywhere. Full, delicate and soft sound: warmer than transistors, independent op amp and power supply inhance the SNR and degree of separation, less interplay and higher sound quality.
• With built-in battery protection circuit: battery lets your listening feast without time limitation. It can't be turned on during charging and will power off automatically after fully charged, and charger LED will turn to green.
• High-end making material and craft: using gold-plated socket, original nichicon electrolytic capacitor, original DALE resistors and precision ring resistance. Prompt and courteous customer service.

User questions & answers

Question:	Why does mine not work?.after charging it,the tube doesnt light up and no sound
Answer:	Make sure all the connection from the wall to the unit is properly connected and secured.
Question:	Is it okay to stick a piece of paper over the circuit board? The yellow is an eyesore
Answer:	The "yellow" color is the copper circuits themselves, which is the main selling point of the product. If you don't want to see the retro design of circuits or tubes, buy a different product.
Question:	Anyone compare the sound quality of the little bear with a more expensive or non portable tube amp? Thoughts
Answer:	I have the Valhalla 2, but it doesnt have the traditional "tube sound". However, what I can say, I have the DT990 and I hate the way it sounds from the Valahalla 2. This amp though, tames it in such a pleasing way. Now, along with those, I use the HD600 primarily for listening. The Valhalla 2 has amazing synergy with them. It tightens it up and make them sound amazing. For portability, I have tried the HD600 with this one as well. It sounds a bit more laid back and closer to what youd expect from tubes with PLENTY of volume. TL;DR: For the price, this little amp is pretty great.
Question:	Can it play audeze lcd2c and dt
Answer:	Don't know, but it does well with dt 990.

User questions & answers

Question:	When will these be available to purchase
Answer:	It’s available now
Question:	Can it run while charging
Answer:	Yes.
Question:	Hi it’s supports iPod and iPad? thank you
Answer:	For iPad Pros and the latest ipadOS, you can just directly use the usb-c to usb-a that comes with this dac. For iPhones and iPods you do need the camera connection kit. I am using it with my iPad pro 2018 with the included usb-c cable
Question:	can this be used for my car stereo
Answer:	I strongly advise against doing so. I'm assuming your question is "can I plug this into the auxiliary input on my car?" In which case, no. Doing so would be "amping and amp" and that's a no-no in electronics. You run a really high risk of burning up both things when connected in this way. The Hip-Dac is one of the few products in this product category that does not provide a line out or a pre-out. It also does not do bluetooth. Typically I find that a phone's or mp3 player's headphone output is sufficient to plug directly into a car stereo. The road is not a great place for hearing that last 10-20% of fidelity these products provide. However, if you still need the option, the Topping NX4-DSD and the Fiio Q1 mkII are similar products that offer a line-out that you can use to plug into your car stereo.

Answer:	In performance, both models incorporate the 32-bit ESS Sabre DAC chip, the 9010 in Black and the higher-performance 9016 in Red. While the Black uses the same headphone amp and analog volume control found in previous version, the new Red includes the latest ESS headphone amp and a bit-perfect digital volume control that resides on the 9016 DAC chip itself. In power the Black puts out 1.2 volts: enough power to drive all preamplifier input circuits and a wide range of efficient headphones. The red with its higher 2.1-volt output will be compatible with a wider range of headphones, including power-hungry, low-efficiency model.

Answer:	I hesitated to answer this question since it's about 4 years old now, but I'm sure somebody else will be wondering the same thing. I must say it's one of the most illogically comical questions that I've ever read. Let me explain. It's like asking if using jet fuel will improve the grass cutting performance of a lawnmower. Obviously, it won't. You just need a more efficient lawnmower. The DAC + preamp + plus headphone amp merely will make the headphones louder but NOT make them sound better. In fact, most low-cost headphones (in the $10 - $30 range) typically suffer from sibilance (hiss), muffled bass, tinny highs, too dominant mid-range, and distortion at higher volumes due to using low-quality components. Therefore, it's highly probable that the AudioQuest DragonFly will make cheap headphones sound exponentially worse. As the old saying goes: "You can't make a silk purse out of a sow's ear."
Question:	If both outputs are connected, one to headphones and the other to speakers for example, can I choose to have sound only in one of them at a time
Answer:	Yes, the Creative Sound Blaster Play! 3 features the 31 Hz band and +/- 24db choice.

2. Can I connect the K3 with an iOS or Android device?

The K3 is a USB power and data combo interface，designed for desktop computers or laptop. Mobile devices are not recommended.

3. Can the K3's coaxial and optical outpu work at the same time? And what sample rate are supported for the both outputs？

A:K3's coaxial and optical can output simultaneously with the headphone port, and is not subject to volume control. Coaxial can support up to 192k/24bit and DSD64 DOP output, while Optical can support up to 96k/24bit.

4. Why sometimes there is no sound when K3's coaxial and optical output is connected to the speaker?

A: When the PC player output device is set to "KS"or "ASIO", the sampling rate of K3's Coaxial and Optical output is followed by the tracks themselves. However, most speakers on the market with SPDIF input only support 48kHz sampling rate, so there will be no sound output. For this kind of use environment, it is recommended to set the output device to "DS" or "wave out" on the music program on your computer.

5. Can the K3's balanced headphone output and 3.5mm single-ended headphone output work at the same time?

A: The K3's balanced output has a higher priority than the 3.5mm single-ended(SE) Headphone out, so when the K3 is connected to both the 2.5mm balanced and 3.5mm SE headphones, only the balanced output port will output sound.
