Audiophile Quality, Connection-Free Convenience, and Portability: PSB M4U 8 Wireless Noise-Canceling Headphones Feature 24-Bit Bluetooth aptX HD, NFC Pairing and RoomFeel Technology
Look ma, no wires! Engineered to play music with the clarity, naturalism, and aura of a live performance, PSB M4U 8 wireless noise-canceling circumaural headphones also marry audiophile quality to connection-free convenience. M4U 8 utilizes the cutting-edge 24-bit high-definition version of Bluetooth aptX HD to deliver accurate, involving sound more commonly associated with wired ‘phones. These NFC-pairing ‘phones also go a big step further with trademarked RoomFeel technology that adds layers of realism. Carefully developed to produce room gain – the energy and clarity a room emits when listening to high-quality loudspeakers, RoomFeel places the music around you and results in noticeably added warmth, richness, and balance. RoomFeel can be enjoyed in both active noise-cancelling mode and active mode.
An amplified, tri-mode, collapsible, and closed-back design, M4U 8 lasts up to 15 hours in Bluetooth or active mode and, if you run out of charge, can be switched to passive mode and continue to be used. In addition to Bluetooth connectivity, a 3.5mm wired connection and a USB connection to hook up from your computer that charges the unit while in use expand your listening options. You can even answer your phone when experiencing Active Noise Cancelation, which employs four adaptive microphones that let you listen to the outside world for as long as you need. Just press a button and the volume will reduce by 30dB.
Intended for travel as well as serious listening sessions, the lightweight M4U 8 arrives built for comfort with soft, two-way, gyro-suspended adjustable ear pads with excellent ergonomics as well as an easily adjustable, expandable headband. NFC pairing, volume/playback/monitor controls, two hands-free microphones, rechargeable AAA batteries, carrying case, airplane adapter, stereo adaptor, standard 3.5mm cable, and micro-USB cable round out a pair of headphones that will allow you to shut out the chaos around you, relax, and become one with your favorite artists. 100% Music Direct Guaranteed.
"I never found a track that these headphones couldn't handle very well. From explosions to dialogue, strings to distorted guitar, faithful reproduction was natural and effortless."

More on PSB's RoomFeel Technology
If you take a direct radiating speaker that measures flat in an anechoic chamber and put it in a room, you'll find that it will have a significantly warmer sound. This happens because as frequency gets lower, the speakers radiate more omni-directionally, and therefore, the sound's low frequency content in the room as a whole gets stronger. In headphones, of course, there is no room response in the equation, and designers have typically either attempted a flat response into the lowest notes or added a big bass hump to satisfy bass lovers. However, no real thought has gone into making a headphone response match that of the typical low-frequency boost heard in a good room. It is here that Barton's long expertise in matters of acoustics comes into play, as he has developed a very well-reasoned headphone target response curve that takes into consideration low-frequency room gain, and a number of other characteristics of a speaker's sound in a room, which we call "RoomFeel."
