The Diamond BTM300 Bluetooth receiver is lightweight and compact. It offers great audio quality in a hands free speaker that doesn’t have to be constantly charged. From a distance of 10 meters (33ft), the exceptional sound quality and hands free controls for both your music and your phone will surprise you with this device.
While Diamond claims it’s rechargeable 240 mAh battery lasts 10 hours, our test results indicated nearly 8 hour battery life which is still pretty decent for that battery size. Although it didn’t last quite as long as expected, the device can still be used while being plugged in to maintain a full charge. Considering the quality the receiver has to offer, for only $39.99 USD on amazon.com with a 1 year warranty, this is a cheap and great way to upgrade that old stereo into a modern media player. The Diamond BTM300 Bluetooth receiver earns the PureOverclock.com Great Value award.
