Review: Excellent Value - This amp is amazing. It feels high quality, is slightly heavy, and supports both my 3.5mm and 4.4mm connections. It has a bass boost option that works as intended, and a mono/stereo separation. The knobs feel high-quality. I am able to bring the input and output gain considerably high without noticing any static or clipping. Although only rated for 100 ohms, it easily powered my 250 ohm DT 770 pro set of headphones. It looks professional on my desk, and performs and feels professional, too. Overall excellent value!
Review: Words aren't enough - My pc wasn't producing enough volume to my earphones. So i decided to research and the best solution was a small amplifier. This was affordable and works for multiple aux devices. The beautiful design and knows make it a great and professional experience. My first amp and fell in love. Great quality work. Will definitely buy from this brand seller. Recommend it for those looking to get more volume out of our machines. Beautiful tones and no static. Perfect little amp.

## Questions & Answers

**Q: Can I connect a speaker to the headphone amplifier output?**
A: This headphone amp is for headphones only, not for direct speaker connection. It lacks power to drive passive speakers. Improper use may cause distortion or damage. A separate power amp is needed for passive speakers.

**Q: Why is there noise or buzzing when I use the headphone amplifier?**
A: This may occur with a non-original power adapter, loose cables, or nearby interference. Use shielded cables, avoid max volume, ground devices properly, and keep the amp away from microwaves, phones, tablets (e.g., iPads) and Wi-Fi routers.

**Q: Why is the sound distorted when using the headphone amplifier?**
A: This can happen if input volume is too high, amp output is too loud, headphone impedance is incompatible, or power adapter isn’t original. Try lowering input/output volume, using standard 32–100Ω headphones, and always use the included 12V adapter.

**Q: Why is there sound in only one ear when using the headphone amplifier?**
A: If you're using a stereo sound source, make sure to press the Stereo switch button on the amplifier. Otherwise, only one channel may be heard. Also check that you’re using a TRS (stereo) cable and it’s fully plugged in.

**Q: How should I connect the headphone amplifier to my devices?**
A: PC: Use rear LINE OUT/AUX/headphone jack; avoid front for better signal. Phones: 3.5mm-Type-C/Lightning adapter (some auto-pause—resume). Tip: No phone grounding—avoid touching. Important: Volume <80% to avoid distortion.

### ⭐⭐⭐⭐⭐ Works Perfect; Meh Power Supply
*by O***O on October 12, 2025*

I need the audio coming out of a laptop to go to two separate and unique headphone sets for live monitoring. This worked perfectly. The knobs feel good, the body is metal and has a good weight, no static or buzzing, and having both 1/4 and 3.5mm jacks for each output is convenient. The only wish I have is that the power input could be USB C for flexibility as the included power supply has a fairly short cable; otherwise it's exactly what I needed.
