Review: Great handy device to convert wired earplugs into bluetooth range. - Good product, normal battery backup issue which is okay. It can handle many useful hours after one full charge, so it's over all good product. However, it keeps my head away from bluetooth device which all I wanted I simply plug in my wired earplugs and keep this device in my pant pockets.
Review: Worst bluetooth reciever, works but quality not usable. - Information mentioned in listing is not correct. It mentions HD codec/voice but only connectivity band is SBC, not even AAC, leave alone AptX & Lossless AptX and LDAC. So as expected after seeing the connectivity band, sound quality is awful. One should go for this product only iff you don't care about sound quality, only thing that you want to achieve is to convert something to wireless and you're too much tight on budget, else please go for some other little costlier options.
