Smart touchscreen charging case

The NANSLS T20 in-ear earbuds arrive with a smart touchscreen charging case that lets you control music, volume, calls, EQ modes, wallpapers, timer, flashlight, camera remote and a find-earbuds function directly on the case. This reduces the need to reach for a paired phone during everyday use. Buyers who want a traditional button-only case will not find that here.

ENC microphones and dynamic drivers

Built-in ENC microphones reduce background noise during calls for clearer voice pickup in work, commuting or daily conversation. Dynamic drivers deliver rich stereo sound and deep bass for music, videos and games. The headphones do not support advanced codec selection or user-replaceable ear tips.

Bluetooth 5.4 with 48-hour case playtime

Bluetooth 5.4 provides fast pairing, stable transmission, low latency and automatic reconnection after first setup across iPhone, Android, iPad, tablets and laptops. The case delivers up to 48 hours of total playback and up to 69 hours per charge with the case, while IPX7 waterproofing resists sweat and light rain. Users needing multi-point pairing or longer single-charge duration should look elsewhere.

Questions about this item

How long do the earbuds themselves last before I need to recharge them?

Each earbud provides up to 6 hours of playback on a single charge, and the charging case extends total listening time to 48 hours before you need to plug in.

What limits continuous use the most — battery life or connection range?

Battery life is the first limit; the earbuds run for 6 hours per charge while the Bluetooth 5.4 link stays stable up to 33 feet.

Do the earbuds get hot or noisy during all-day use with the touchscreen case?

The in-ear design stays lightweight at 0.11 pounds and produces no audible fan noise; the case display adds negligible warmth during extended sessions.
