CARD20 is the world’s slimmest TWS Bluetooth headphones combining classy look, sublime comfort and unparalleled audio performance. The patented layout of the built-in antenna and the seminal cutout design of the charging case squeeze the total thickness of the earbuds and the case to a mindblowing 0.5in in striking contrast to at least 1in of others. Each component is strategically arranged based on the form of over thousands of human ears to dramatically improve its universal comfort, fit and stability.

CARD20, with its slimness and compactness that are second to none, is hands down the thinnest and smallest TWS headphones in the world. It is only 0.5 inch in thickness measured with the charging case, which is easily 40%~70% thinner and 60%~80% less bulky than others in the market.

CARD20 will always be ready to go the next time you need them. The charging case provides more than 16 hours of listening time with multiple additional charges to the headphones. They can play music continuously for up to 4 hours at full volume, or 5.5 hours at 70% full volume on one charge.

Rated IPX4, CARD20 headphones resist sustained sweats, splashes and sprays, keeping up with you during the most rigorous challenges. CARD20 employs advanced CVC algorithms by Qualcomm which cancels out echoes and suppresses ambient noises so it appears you are in a quiet indoor space when you are making a call. It also features a nylon microphone net that improves call clarity in windy situations. CARD20 will always be ready to go the next time you need them.
