VOZA BD210 Alexa Built-in Portable Bluetooth DAC Amplifier Makes Any Headphone Wireless

The main thing why I ordered this was to enhance the sound of my mp3 files from my iphone to my sound system. It does not disappoint! The sound coming out from my system speakers are crystal clear, just like what is advertised. The volume control is redundant. It merely duplicates the volume control of my phone. Very portable, and the battery lasts at least around 8 hours per charge. You can use the unit while charging. My only dissapointment is that the gain control goes to the default mode(in-ear) everytime you turn the unit off, your preferred last setting gone. But overall a great buy at an unbelievable price. It’s sound is way better than the $100 DAC bluetooth available here at Amazon.

I really didn’t expect much from this. I had tried an Earstudio es100, FiiO btr3k and this little cheapo $30 device blows them away. It was initially a little fiddly getting it to connect via Bluetooth to my iPhone, but once I did it locks on every time now without issue. The amp and sound quality are also shockingly good. My 26ohm IEMs are plenty loud at around 25% volume, which is significantly better than the Btr3k and similar to the es100. It also instantly works as a usb dac in windows 10 without any issue which couldn’t be said for the es100. Build quality isn’t as good as the FiiO but so what, it sounds much better and is lighter weight.

Regardless of the input or headphones/earbuds, there is a constant blipping static in the background with these that ruins the listening experience. If you turn these up, it drowns it out except in quiet passages, but that’s not really a fix. On the plus side these can get ear-damagingly loud and sound good doing it. But again, that static is always there in the background reminding me I should have bought a better headphone dac.

I wouldn't either but this little Headphone AMP is the best 35 dollars I've spent they will make your headphones, small speakers sound the best ever that's all I can say about it just buy one if you don't agree send it back but I bet you won't, you will be amazed

Great quality sound,volume,portability bt connection truly HE RE sounds,needs a clip holder that’s why I’m buying it again,lose it my first one and like it,tried fiio BTR3,Boza has no distortion at full volume plus eq and gain choice ,transfer file to Flac and he re player and headphones to get the full experience of this little monster I recommend!!!!!!....

If you have decent iems, this small amp is worth every penny. Listening to hi def Amazon music right now. Outstanding. I’m surprised that this inexpensive device doesn’t get much attention.

Always looking for a great headphone amp. This little sleek amp is well done. Works like it should. Bluetooth is great. Now for the sound.. crystal clear and clean. If you have some premium (or average) wired headphones that you want to flex... give this little amp a try.

These are some of the most detailed dac/amps you can find for under $150And the chewing gum stick size make them easy to carry around.I purchased 4 and keep 1 with every pair of iems I own.
