Smart and quick charging
The smart and quick charge feature enables the battery to be fully recharged within a very short time span. The remaining power capacity present in the battery is determined by an internal circuit, so that the incoming voltage can be optimized for a quick recharge while at the same time maximizing the battery lifespan.
2.4 GHz digital transmission
The 2.4 GHz digital transmission prevents compression and data loss between the transmitter and the headphones. The digital signals are converted to analog signals at the end of the sound quality, with smooth acoustics and minimal data loss.
Acoustically tuned speakers
Acoustically tuned speakers produce pure, balanced precision in both the high tones and deep bass levels.
Self adjusting inner headband
The inner headband of these Philips headphones makes it easy to obtain a perfect fit for your head. The mechanism adjusts automatically for comfort.
