Add New Life to Old Systems with RCA Inputs.
Bought this product to add Bluetooth connectivity to my retro CD system so that I could stream from Spotify on my phone. The stereo is over 20 years old, so the benefit of this particular item in having RCA AUX input was perfect for my needs. Connected without issue, responds to volume changes instantly and quality seems good enough through a 50w amp running through floorstanding speakers. Definitely a neat and simple solution to modern music on an old system. At an estimate, I’ve been circa 15m from the music player and it didn’t drop signal, but this was only for 30-60 seconds.

Two simultaneous outputs
It sends the audio to the RCA outputs and the 3.5mm output at the same time. So you can feed two devices simultaneously. For a teenage party, I did this to send the music to two different rooms at the same time. There was a stereo in each room. The unit was in the middle. I used long cables to feed each stereo. People could move between the rooms and the music was in synch. It worked well.There were no lost connections or interference all night. I didn’t choose it or test it for sound quality, but it sounded OK and we got good volume without distortion.The only niggle is that the user interface is unintuitive. There is only one button and an two-colour led. The instructions explain different types of button presses for each function (eg on, off, pair) and the led patterns that tell you what’s happening. On a light read, these weren’t too clear. Looking at it, it’s hard to see if it’s in or off. But these are not big points.

Awful with decent headphones.
Looks great, professional and good build quality but the charger and adaptor cables were missing.And it doesn’t have a battery so it has to be permanently powered.If that wasn’t bad enough the thing sounds like the “top end” is missing despite UGreen claiming it can go all the way to 20Khz – which is usually the -3dB point and most of us can’t get close after our 20s.But even at my age and with hearing problems like Beethoven (who knew?) I can’t hear the brighter audio. Sound from the TV was flat and uninteresting (vs. the internal speakers which produce a respectable range (Dolby Atmos my foot, Panasonic). Similar story on the Steam Deck. Paired without a problem but the audio was flat, lacked bass and high-frequency information. And this is into some BeyerDyanmic 990s (superb cans, available from Amazon which is where I got mine). The Beyers produce excellent detailed audio even with HRTF 5.1, 7.1 and 9.1 sources which is what attracted me to them.If I had the time I’d run a full sweep to see what the thing is actually capable of but I’m going to have to return it and replace it with something that does work. Low latency is great and all, but the amplifier (presumably a Class D SOC) lacks detail and sounds muddy. Sorry Amazon, this one is not what I expected.

Okay, but low volume and needs re-connecting after idle
The volume output is low requiring you to turn up the volume (usually to full) of whatever it’s connected to. If you use your amplifier/speakers for anything else, you’ll get blasted if you forget to turn the volume back down again.It’ll disconnect when idle, so you’ll need to reconnect whenever you use it again.That said, when it’s actually playing it works fine.

iPhone13でイヤホンコネクターを使っていたがしょっちゅうコネクターが壊れるので、ワイヤレスに変更。　音質も問題なく快適に使えています。

Kesinlikle mükemmel. Stereo ve net bir ses iletimi.
