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.

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.

I purchased this for an elderly friend who uses wireless headphones with a television.It connected quickly to his budget headphones and has been working flawlessly for him.

This product, although it did connect easily enough to multiple Bluetooth devices (which was nice), came with a terrible distortion of the Audio. There was both crackling of the audio output with buzzing noise constantly present.This is was likely due to poor assembly, of the unit itself, as I tested the provided 3.5mm cables (as well as a higher quality cable - purchased separately), with alternative devices for both input and output functionality, and the issue was only present on this device. I also tried several different USB cables just in case.My guess is that the issue was in the 3.5mm Audio Jack (Female) on the receiver/transmitter itself, which was either poorly manufactured and not making a good connection, or was poorly soldered in the wiring.This unfortunately made all other aspects of the product moot points. With an item such as this at such a low cost, I was not expecting the greatest results, but I did not expect the simplest of aspects to be of such poor quality. This may have been due to a bad batch of components, a novice assembler, but it clearly did not receive sufficient QC testing even at a low level.Could it have been damaged in transit? Yes, but the unit was not damaged, it was extremely light, and if the soldering came loose in transit, than the soldering job was sub standard.I could have requested a replacement, it could have been a bad unit that slipped through sub-assembly, but this is literally the simplest part of the product for both assemble and testing.If you are looking for a very cheap alternative to more expensive comparable products, you can give it a try, but I would not expect much here. If you do try it and receive a unit that does not have the same issues I had upon arrival, I feel it is safe to assume the products longevity would be very limited, and failure would be more likely than not to occur especially if you are plugging and unplugging the unit into different devices.Rated a 2-star because Bluetooth connected seamlessly, which was the only plus I can provide it.PASS on this item unless the Manufacturing can resolve such a basic issue.
