Works well, battery and disconnect voice is loud, though
Took a leap of faith and decided to buy a cheaper Bluetooth transmitter, got lucky on the fact that it works well, only downside is how loud the low battery and disconnection announcements are

Works great, after a rocky start
Update: Was using the transmitter with my Airpods and the Bluetooth kept cutting in and out. One time when it came back, it came back LOUD and since then, the volume has been fine. I am not sure what made the volume raise, but I wanted to update as the device is working great now. Also changing my rating. Will update if the sound gets low again. I had purchased this to listen to my iPod Classic with my AirPods. It connected fine, but the volume is so low that I can barely even hear some songs, even with the volume on the iPod all the way turned up. I had the same issue when I plugged it into a PC as well. It seems to work better as a receiver (for instance if you are plugging it into the aux port on your car or another device). If you are looking for a transmitter, look elsewhere unless you don't mind very quiet audio.

Not for real time audio ....
This product works great for non real time audio where latency is not an issue. Sound quality is great. Pairing is flawless (at least for the Apple Ear Buds). But ... for real time audio as in a studio situation, there's at least a 50 msec delay, maybe more as I had no way to measure (and I spent little time checking further after I noticed the delay). Using to monitor an instrument or vocal in real time just does not work. There does not seem to be any way to reduce the buffer size and therefore delay. I will keep looking. My fault for this ..... for not checking so it will just go in a drawer and maybe be used for some future one-off application. Thought I'd let you know.

Works. But, lacks volume.
I charged the device as soon as I unpacked it. Charged up fairly quickly. Bluetooth connected fairly easily to my Skullcandy Grind True Wireless earbuds. Connection seems solid. I can hear a little electrical interference, especially when I put my hands on or around the device. I bought this especially for use with my Audiovox portable DVD player that I've had for many years, and it is rock solid but lacks wireless capability. So, I decided to try this route to free myself from the last vestiges of wired earbuds/headsets as I'm spoiled to wireless. I don't want to, nor do I need to replace my DVD player, it was a birthday present from my beloved wife, it works great, and has a great 10" screen, a battery, car plug, and mains power supply. Really great when sitting, as I recently had to for 4 hours, in a long line that isn't moving! Back to the device: it functions well and as advertised in a nice small, lightweight package, and includes the necessary cables, but lacks any kind of pouch or case - which I like to have for my small devices, especially multi piece. I got everything connected, and it works ok except the volume, at full volume setting on the player and device, are so low that any noise in the area, including low volume conversation, makes hearing the DVD dialogue. For some reason, the dialogue is distinctly ''layered" where you can most clearly hear the primary character(s) dialogue, then there's a distinct drop off in volume in "support/background" character(s) dialogue. If you adjust the volume downwards, at all, you hear nothing. I tried adjusting volume on the device, but it doesn't respond, and same for the Skullcandy earbuds volume control. I have another set of wireless earbuds, generic brand, and got the same results. Only time I can possibly use will be late night when other household members are sleeping. I am disappointed with this. TLDR ; Seems to be well made. Functions well. Except poor volume level.

Solid enough for my needs
Using with my PS5 to exercise. Works just find. Did need an additional adapter AUX to USB because my television didn't have a simple audio aux plug. But proceeded to connect them to my everyday Raycons without issue. Have used them three times and still no problem. The audio won't be controlled with the device, which is across the room when I use it anyway. But I can control audio with the earbuds. Sound quality is good enough and very occasionally spots out for a half a second. But it's not frequent or intrusive. And it might be the earbuds. I'm happy and the price is good.

Better than waking my wife up
My wife works third shift sometimes I like to sit in the living room and watch TV. This allows me to go through my headphones and I’m not disturbing her easy to install easy to connect. Good quality long range highly recommend.

Best Part is that the Unit is chargeable. So once it is charged - it is very portable. However, being Bluetooth, there is some lag in receiving/hearing the audio - which for playing/recording musical instruments or recording vocals, would not be suitable.

Printed manual text is so small, it really is so hard to read; but very clear instructions. Product works great ! Zero regrets !

It does the job well so far. I’ve used it for two weeks every day and I hasn’t skipped a beat. I paired it with my AirPods and worked well. Not the greatest sound quality compared to other BT devices but again, considering its price, it is not bad. It may look a bit cheap made though and it’s not prettiest device to show around.
