Features:

Compact, truly wireless in-ear headphones with digital hybrid noise-cancelling technology
Ambience control (noise-cancelling, hear-through, talk-through) can be employed for music playback and calls
MEMS (micro-electromechanical system) mics, a high-accuracy noise-cancelling processor, and a proprietary filter work together to deliver stellar noise-cancelling performance
Hear-through function allows you to hear ambient sounds (plus your own, unmuffled voice) so you can talk to others around you without removing your earbuds
Talk-through function lets you hear voices/announcements around you by instantly lowering playback volume and capturing ambient sounds while enhancing the vocal bandwidth
5.8 mm high-resolution drivers, adopted from the ATH-TWX9, deliver an extended high-frequency range and improved sound detail
LDAC codec compatibility enables playback of 24-bit/96 kHz audio files
Includes two sets of eartips (XS/S/M/L): Soft eartips for greater comfort during long listening sessions and Standard eartips for a snugger, more secure fit
High-performance MEMS mics, beamforming technology, and two selectable call modes (Natural and Noise-Reduction) ensure crystal-clear call quality
Call test function allows you to check the tone and clarity of your voice
The microphone can be easily muted during calls via built-in controls on the earbuds
Soundscape function plays relaxing sounds of nature, a masking noise to help you concentrate, or sounds for meditation
Private Timer function provides advanced personal time management
Multipoint pairing function allows you to stay connected to two Bluetooth devices at once
Approximately 6.5 hours of continuous playback and up to 13.5 hours of extended use with the charger (for 20 hours total)
A-T Connect app gives you additional control: activate low latency mode, select Natural and Noise-Reduction call modes, adjust and save EQ to the headphones, change codecs, and more
Compact charging case with non-slip finish is easy to handle and carry with you wherever you go
