Kashimura True Wireless Stereo Earphones: High-performance Earphones with ANC (Active Noise Cancellation) and Ambient Sound Mode To Block Out

ANC/Noise Cancellation mode eliminates ambient noise to create a quiet environment. Ambient Sound Mode allows you to hear ambient sounds through the earphones. 4 hours of music playback (with ANC on), and up to 11 hours of playback with the charging case. Touch controls and an easy-to-hold design. Automatic connection function allows the earphones to pair with your smartphone after initial pairing, so either the left or right earbud will remain paired with your smartphone even while charging, making them ideal for single-ear use.
