Kinovo has good range of entry level budget Bluetooth Headphones which are popular through years due to its premium quality. With continuous strive of introducing upgrades, BTH240 has 25% more music & talk time than its precedent BTH220 🙂

Even after introduction of upgrade still BTH220 going well due to lower price-point and ignoring the battery life improvements.

Basically BTH220 itself is very lightweight headset with facility of Hands-Free Calling + Music. Both these headsets are compatible with A2DP enabled handsets like iPad, iPhone, iPod touch, Android Smart Phones etc.
