Review on 🎧 Syba USB Audio Adapter with Built-in Chip – USB Sound Card for Headphones and Microphones, USB to 3.5mm Jack TRS AUX Adapter with Separate Plug – SD-AUD63119 by Carl Henderson

Excellent DAC and headphone amp! For the money, it sounds as good as my Fiio A3 portable amp. And it even has stronger and clearer bass boosts (especially 3rd and 2nd bass intensity settings). And the Syba DAC/amp is only three times cheaper than the Fiio A3, AND it's MUCH easier to travel with 🙂. Charging does not require a power adapter or charging cable as it works without an internal battery. And it only uses the battery of my original device, a OnePlus 7 Pro Android smartphone. I can't believe this sound quality doesn't increase battery drain. And I was impressed by its effectiveness. All my portable audio (YouTube, Android games, downloaded high quality MP3 and Flac files for lossless audio) improved when I connected the in-ear headphones to my smartphone with Syba. I'd even go so far as to say that I'd rather use it as a portable headphone amp even when using my smartphone at home. All my headphones have an impedance of 32 to 120 ohms (Sennheiser, Hifiman Planar Magnetics, etc.). For those of you with headphones that require 300 ohms (impedance) or higher, the Syba still fits. I personally don't have high impedance headphones to test, but as shown in one of the photos I posted, the description on the box says they work with headphones up to 600 ohms. The two photos I posted are meant to show the secure packaging the Syba arrived in. And I have a blue pen next to the Syba to show how small the amp is. The Type-C connector also comes with my Android through a case that I have. So smartphone cases can stay on the phone. This is the most convenient plug and play headphone DAC/amp you can get. 5 stars from me. And worth the price.
