Golvery Bluetooth Receiver for Old Speaker with Latest Bluetooth V5.4, 20-Hour Battery Life, Handsfree Calls, Dual Connection to 2 Cell Phones, Built-in Microphone, for Wired Headphones, Home Stereo

This is one of the coolest little electronic devices.This Bluetooth audio receiver can make any speaker a Bluetooth device. I have an older speaker behind a TV in my bedroom, plugged directly into the TV, to make it louder. Now I can plug this receiver into that speaker and listen to my playlist on my iPhone or iPad without connecting them using an auxiliary cord. It connects with any Bluetooth device wirelessly.For my car,I can plug the bluetooth receiver into 3.5mm Jack port,also can enable the car speaker bluetooth function,and listen to music from my iphone or ipad wirelessly.To use this it does need to be charged first. It took 2 hours to fast charge and it does comes with a USB cord to charge it. Once charged I was able to easily pair it to my iPhone and I was playing in a matter of seconds.And it works long time with 12 hours of playing time, or up to 400 hours on standby.So if you have some older speakers or TV or car kit that do not built-in bluetooth, then this audio receiver is exactly what you need. This is really a great product, very convenient and practical, value for money.

Works perfectly on my Bose wave .

Small bluetooth audio receiver, which lets you receive audio sent by bluetooth from a device such as a phone and outputs the audio to a hi-fi or computer with an AUX input. Device itself has a short lead ending in a 3.5mm stereo jack plug, and you get a short adaptor which converts this to twin RCA/Phono plugs for devices without a 3.5mm jack socket. Connected to my Android7 phone via bluetooth first time (takes a few seconds). Couldn't get the audio files to start playing from my phone at first, until I realised that the button on the receiver is a Play/Pause button which stops and starts the music on my phone - oh dear, I'd hidden the receiver and its short lead behind the PC plugged into the blue AUX IN socket so it was difficult to get at the button! A short extension lead soon sorted that. In use, the device worked well enough, with a claimed battery life of up to 8 hours, charged from a standard USB charger. A short USB A to micro-USB charger lead is supplied, but not a charger. The audio seemed a little muffled compared to other sound sources I'd plugged into the PC, I'm not sure yet if that's just the phone sending lower quality audio or the device itself. Also, when no audio is playing, there seems to be a random clicking noise (OK when music playing), again not sure if that's my phone until I get a chance to try another bluetooth audio source. The tiny but informative manual (the English is a bit weird) claims you can connect two phones at once. It remembers which phone it last paired with unless you tell it to un-pair. A very useful device for transferring audio you've recorded on your phone to a computer for editing or posterity, or to let your phone play music via Bluetooth to a hi-fi unit which does not have a Bluetooth receiver, as long as the hi-fi has an AUX input of some kind. Pretty good value for money.

I purchased this for a specific purpose in mind and if the outcome was unsuccessful, well I hadn't lost much. And if it should work, I argued I could upgrade to something more expensive, and presumably it would also be of higher audio quality. Well, the good news is it worked and did I upgrade? No, as it not only met but exceeded my expectations. BT devices are improving all the time as regards audio quality, but as the sound from this little unit is so good anyway, I'd be reluctant to spend more on the off-chance.The original purpose was to dispense with cable connections and to BT music from my laptop and Shield tablet to a portable mini-disc player/recorder, specifically my Sony MZ-B10, but also to my standalone hi-fi separate MD recorder. I found that this Golvery worked extremely well and playing back DDD recordings from CD via my Sony MDR CD1700 headphones, the sound was truly excellent for BT. This was a severe test owing to the CD1700's transparent mid-range. Playback also revealed that the Golvery was completely immune to electrical interference and didn't add any audible hiss or noise of its own. I don't know what its stated output power is as this would have been useful to know at the start as the B10 has no recording level control on its line input. Happy to report, though, that it doesn't overload the B10's input and loud signals are recorded cleanly.Out of interest I compared the same work on a mini-disc recorded directly from a CD, using my Yamaha S2700 SACD player as the source, to my Sony JB930 QS with that of the same work ripped at 320kbps to my pc and copied to my MZ-B10 via the Golvery. Using the Sony 'phones I found it nigh on impossible to tell the difference. I feel this is proof that the Golvery neither adds to nor detracts from the signal it is passing. This comparison really surprised me as I was fully expecting the direct CD recording to the much higher quality JB930 recorder to be audibly different, and superior.All in all, a great buy.

This works really well. Pairs with my phone very easily and once connected stays connected, not had any dropouts.The battery seems to last forever before it needs recharging. Sound quality is good - slightly lower volume than radio broadcast but not an issue.One slight gripe is that the Aux input lead is short, where my Aux port is makes it a little awkward to access it but not a huge problem. There is an on/off switch - most of the time I forget to turn it off when I'm getting out of car but it just seems to power down itself once the phone is out of range and the battery is fine again on next use. Sometimes need to turn to off then on again to pair the phone if I forgot to turn it to off on last use.For the money you can't go wrong - unless you need a longer Aux lead for an out of the way aux port.
