The Denon AH-C252 is a pair of in-ear headphones, released in late 2008. The AH-C252 integrates what Denon calls Acoustic Optimizer Technology, a system that maintains sounds pressure balance in front and behind the ear pieces. As a canal-type headphone, external noise is significantly reduced. This is especially useful in noisy environments, and can reduce strain on the users’ ears. These headphones have a frequency response of 20 - 23,000 Hz, a sensitivity of 100dB/mW and can handle 100mW of power. This means the C252s can produce a power mid-range and strong bass response. Expert reviews indicate that this pair is best suited for the rock, metal and hip-hop genres. Included accessories include 3 different sizes of detachable ear pieces, allowing for the most comfortable fit. A cloth carrying pouch is also included to protect the headphones.
