It may seem obvious, but I noticed a significant difference in sound quality based on the Bluetooth volume settings. When the Bluetooth volume on the device was set low and the amp or speakers had a high gain, the audio sounded dull and fell well below the usual quality I expect. By increasing the Bluetooth volume on the TV to near its maximum—leaving some headroom for volume adjustments with the TV remote—and reducing the amp's gain to maintain the same overall volume, the sound improved dramatically. The audio became much cleaner and brighter, with the speakers delivering a quality comparable to a direct line-in connection.

Ideal if you haven't got a Bluetooth in the car works brilliant simple to fit does exactly what it's supposed to small discrete good quality probably by another one at some point if I need it.It is ideal if you don't have Bluetooth income just connect to exhilary everything that your phone play that will play

Arrived quickly and works fine

My yamagata receiver has built in Spotify but not Bluetooth, as it is an earlier model.This box has resolved all of that.Simply connect with the lead provided into a spare port, pair up to your devices, which was quick and easy. Select on your system, I connected to AV2 on mine and all done .I highly recommend to anyone who is looking to combine old school hi fi and streaming without having to spend big updating their system to do so.

I’ve tried a few Bluetooth receivers recently and this one was probably the best.It has a very honest sound with a flat frequency response and a pleasantly detailed sound with low background noise. It was also the only one that I tried that could take it’s power from an amplifiers USB socket without introducing digital noise into the amp (some Bluetooth receivers contaminate the sound of the amplifier and need their own USB power adapter). You can also re-name the Bluetooth receivers name from the bluetooth settings menu of some phones, tablets or computers.

Product is great however it does remain on for a while after being disconnected from. If it automatically turned off after being disconnected from it would be 5 stars. However, still does a good job with my old Hi-Fi system and there is no feedback noise.

It’s ok and does the job.Only seems to work and power up when connected to a power supply.Previous ones I’ve had have all been rechargeable.

Wanted to add connectivity to my hifi amp...and this works a treat..very pleased ..low price..discreet..stable and easy connection. If you disconet it will turn itself off after a while and you just need to press the big button on the top to wake it up. Also comes with all the cables you need. You just need a usb socket or plug to power it.Well worth the money
