Anker Soundcore K20i wireless semi‑in‑ear earbuds. They run on Bluetooth 5.3 and support a 10 m connection range, while offering up to 36 hours of total playtime (6 hours per charge for the earbuds themselves). A quick 10‑minute top‑up charge gives about 2 hours of listening. Each bud weighs around 3.3 g and they have an IPX5 rating for sweat and light‑rain resistance. The K20i is equipped with dual ENC microphones for clearer calls via AI noise reduction, and its sound output is driven by 13 mm drivers with BassUp enhancement.
