Teac Headsets

3. TEAC HP-7D

These headphones have all the advantages of HP-6D, being also USB Audio controller based, with the major difference that they offer a real 6 channel sound, with 6 speakers build in. As a result, these speakers definately do not feel like the sound is comming from one's head. In addition, the sound quality of these headphones is quite impressive. Dividing the energy in to six speakers means that less stress is put on each individual speaker, hence the result is crisper, clearer sound with a very deep bass. Especially the bass speaker seems that is not sweating at all, and can be further pushed by utilizing the equalizer of the driver, without major cropping and distortion. Medium and high frequencies are quite accurate as well, allowing details to be heard.

Build wise, the headphones are slightly too tight (or my head is too big) and the fluffy velvet surface of the "ear pillows" is not the best material for hot climates cause it gives a warm feeling at the ears. Other than that they are comfortable. On top of the driver features/settings that HP-6D have, this driver offers the "monster / cartoon" effect which alters the way your voice sounds in real time making it a wicked suprice for online games that support voice.

Microphone comes on a separate flexible rod, that optionally connects to the headphones via a small jack. This allows better placement of microphone when used. In addition good size foam is used for protecting the mic from air blows. As a result the mic has a very good reception, allowing the sensitivity not to be set to maximum, resulting in very good recording quality.
