The Anker Soundcore Liberty Air 2 True Wireless In-Ear Headphones. Black version.

Features:
- Diamond-coated driver. Earphones take advantage of the ultralight rigid structure of diamonds to create a driver dome that maintains its rigidity, even when vibrating at high frequencies. Around its exterior, there is an elastic, bass-maximizing ridge to reproduce thumping low frequencies.

- Four microphones for crystal clear calls. Each earbud is equipped with two microphones that use cVc 8.0 noise reduction technology. Your voice is optimized, and background noises are minimized so you sound louder and clearer on the other end.

- HearID technology. Take the test to create a custom set of EQ settings that are optimized for your ears. HearID maps your hearing sensitivity at multiple frequencies and intelligently analyzes the results to give you a truly personalized listening experience.

- Qualcomm aptX audio enables CD-like quality wireless audio because it solves the problem of sending the full music bandwidth over Bluetooth.

- Rechargeable battery, A single charge gives you up to seven hours of listening, while the charging case extends it up to 28 hours of playtime. And when the case needs a power boost, simply set it down on a wireless charger.

- True wireless provides a stable connection and lossless sound transfer in each earbud when streaming media from your device.
