FiiOBTR11 Bluetooth 5.3 Receiver LDAC 3.5mm Wireless Audio Headphone Amplifier Adapter (White)

Great little LDAC for its price! It makes a huge difference with my IEM headphones for a fraction of the high end stuff, great for daily usage. Not only it is for audio, it works well with on broad microphone and in car or out of car usages. Compact yet it delivers a punch with its adaqute bass. LOVE IT!

High quality and works really well on PC with Alternative AD2P drivers installed for specific codec selection on windows. The main drawbacks are power output on overear headphones being a little weaker than IEMs, volume steps are somewhat inconsistant in windows, the range and signal integrety being a little spotty even when near my pc (it could just be the specific codec selected but the kind of sound issues sounded more like a line of sight issue rather than just a bad connection), and the weight of the device itself means that its better suited to being wrapped and then clamped on to the cable around your neck or in a pocket. The battery life is respectable and can get through 4 or 5 hours depending on the headset used. The audio prompts could use a revision as they are oddly worded and sometimes unclear sounding, but they get the job done. At around 20 dollars it fills a very specific niche extremely well.

This is, as far as I can tell, identical to the Fiio microBTR that they discontinued a few years ago. It looks the same and works the same. They are really great. I work outside and I use these so my wired headphones aren't hooked into the phone. The battery lasts 8-9 hours, which is longer than others I've tried. I mostly listen to podcasts, and for that the sound quality is great. It works with Android and iPhone. The buttons are simple, one for on/off/pair/pause and a toggle for vol up and down. It connects quickly and it has good range, I can leave my phone on the other side of the room with no issue.

This dac from Fiio has been an excellent product for the price. I wasn't expecting how good it would sound as it supports LDAC. The bluetooth connected on the first try and I was able to update the firmware using the Fiio app. Through the app, there are not many features supported, but it handles music well and has a good range when walking away from my phone. It doesn't have any inbuilt EQ that I could find, so I just use Wavelet on my phone to handle that. If you are looking for a cheap bluetooth adapter to use for your IEM's, you cant go wrong with this one.

The BTR11 has some strong points like LDAC support, compact size, and good audio quality for music. It’s lightweight and easy to carry, and it can turn wired headphones into Bluetooth ones without much hassle.That said, there are a few downsides. The microphone quality is not great, and there’s no mute button, which makes it less practical for calls. The battery only lasts about 7 hours for me, far less than the advertised 15. Another annoying issue is the faint hissing sound when the device is idle, which can get distracting in quiet environments.Overall, it’s decent for music, but the weak mic, short battery life, and background hiss keep it from being better than average.

This is a great little source device, especially for its price of around $20. One thing to note, however, is this device does not connect to multiple devices at once, or switch between devices easily. Instead I have found I need to disconnect and forget/unpair the device before adding it to another device to switch between them. Unfortunately this needs to be done EVERY SINGLE TIME, so this should really be considered as a bluetooth output for a single device/usecase. This is a fine tradeoff considering the price, but something a potential buyer should absolutely be aware of.

Arrived more quickly than the shipping estimate. Sounds clean with no obvious issues. Paired immediately with both iPhone and Windows 11 PC and reconnects quickly when powered on. Strong signal: I've gone into the basement with my device on the first floor or two rooms over and have only had one brief reception fuzz-out so far (through two walls). Case is thin plastic, but that's expected for the price. The positive side of that is feather weight, and it probably helps reception vs. metal. Greatly pared down, cheaper alternative to the Qudelix 5k, which I can't afford right now, and fills the need well. No EQ, unlike the Qudelix, but I can parametric EQ from my PC with Equalizer APO. Feels kind of like walking around with an iPod or Rio used to, which is fun. Small enough to disappear in your pocket and leave plenty of room to avoid feeling weird with a coil of headphone wire in there too, unlike with a phone. Recommended!Edit: meant to mention also that battery life is excellent.

Excellent quality. Feels sturdy and well built. The clip is a great addition so that i can easliy clip it onto my shirt or shorts.Bluetooth connection is good and connects very quickly.Sound is phenomenal paired with a set of Tinhifi T3 Plus.
