Analysis

Build Aspect

CX 120BT Bluetooth earphones is a budget pair of earphone offering from the house of Sennheiser. The construction makes use of plastics and rubber string that goes around the neck. The earphones look rather decent and premium. As a result of their feather light weight the comfort levels are excellent. In ear fitting is also secure and very comfy. On the down side their battery life is rather poor at just 6 hours of playback time.

Performance Aspect

The sound signature of CX120BT is very neutral and balanced. While they do not have an excessive bass heavy sound like some other wireless earphones and headphones, it fares really well by being relatively more flatter and more natural sounding. However this could leave some of the bass heads asking for more. Furthermore the mid-range and treble have a well tailored and fabulous output, they are detailed, with lots of flair and dynamics. In brief Sennheiser CX 120BT are a decent pair of natural sounding and perhaps one of the better sounding wireless earphones in their price range in India.
