Thread: Sennheiser CX400 Headphone

Sennheiser has amped up the audio quality of the eX300 headphones, particularly in the bass frequencies with the eX400 set of noise isolating ear-canal phones. The box ships with small, medium and large earpieces, so that it fits in every ear, and a one meter extension cable. The earphones are lightweight, and since they sit right in the canal, there is no need to turn up the volume on the device to full to hear the audio. The wires are sheathed in rubber tubing to minimize damage.
