FiiOBTR13 Bluetooth Headphone Amplifier with LDAC, aptX Adaptive, aptX HD, AAC (Dual CS43131 3.5mm Unbalanced & 4.4mm Balanced Output) (Blue)

good battery life and drives all my headphones fine including my pc38x and some earbuds. I only use it on half volume and it's plenty loud. When you first power the device it asks if you want english or chinese and you can also change that in the settings on the device. One thing I don't like is that you have to use the app on your phone to change some settings such as the audio codec, but it's not that big of a deal. Overall it's been well worth the money because now I can use any of my headphones "wireless" and when choosing a new pair of headphones I don't have to buy bluetooth headphones if I want to use them wirelessly.

This is my 2nd fav DAC and first Fiio device. I am thoroughly impressed with it's build quality and usability. Though the software update process needs to be more intuitive. It sounds great and seems to last for weeks.This little DAC led me to buy the btr17 and I'm even more of a Fiio fan

The people that are saying it's only in Chinese are wrong, the first time you turn it on it gives you a clear choice between Chinese and English

This is a good product, makes your wired headphones wireless while also providing a boost of power to headphones that may be harder to drive. Small and has a beltclip for on the go use. Would recommend especially if you wanna pay less than $100.

Love the sound, love the app, love everything but the battery! Mine is brand new and I’m getting MAYBE an hour or two nonstop. If I use it on and off, sure, it lasts. But I can’t get through a full hour plus workout after leaving it charging all night. That’s crazy!! This could be a super bargain at $70, but a portable with low battery life isn’t worth the money at any price!

So. I can honestly say, I don't use this thing. My phone battery is trash most days so I use a Mp3 player to listen to my music. And since the bluetooth works on my mp3 player I haven't had a use for this thing though I did test it and it does work, I've mainly used it as a dac for my laptop. I did use it for my phone and it sounds good. And the signal doesn't drop out when I walk out of the room or across the hall. That's the only thing I would say was wrong with my BTR15. The BTR17 tends to give me trouble too and while I haven't tested this thing extensively I can say my unit works with everything I threw at it. It also has a built in clip. It feels cheap but now I won't be afraid to drop it if I ever decide to use it outside of the house with my phone. I used it on my Mp3 player and the volume was so low on bluetooth and you can't use it wired so to tell you the truth I probably should've sent it back but I'm hoping to give it more of a purpose in the future.

Great product connects wireless to sound

Poor excuse for audiophile equipment
