Sony ULT POWER SOUND series / ULT WEAR Wireless Noise Canceling Headphones

ULT Wear key upgrades
The headphones also have some other key upgrades, including new 40mm drivers that Sony says deliver even deeper bass. The ear pads have a wider opening to accommodate bigger ears and are slightly more comfortable overall. You also get new beam-forming microphones with wind noise reduction, as well as Sony's V1 chip that improves noise-canceling performance and ear-detection sensors that pause your audio when you take the headphones off your head and resume playback when you put them back on. 
 
The headphones also have a higher battery life rating. It's now up to 30 hours with noise canceling on and 50 hours with it off. A quick charge feature gets you 90 minutes of playback with a three-minute charge or five hours with a 10-minute charge.
