Product Description The PHNC65 High Fidelity Headphones are a closed, dynamic, ear‐enclosing stereo headphone with active noise canceling functionality. Disturbing ambient noise in the low frequency range is recorded by tiny microphones and then significantly reduced as phase inverse tones. Thus, a noise canceling of more than 85% is achieved. For operation: two 1.5 V micro batteries {type AAA} are required. The PHNC65 can also be used passively (without noise canceling and without batteries). The swivel headphones come complete with a practical transport case and two audio adapters. 1. Product Overview 1) ON/OFF 2) Power indicator 3) Volume level 4) Battery cover 5) 3.5mm audio jack 2.
