Designed with four microphones, the EarFun Air Smart True Wireless Earbuds cancel noise for crystal clear calls. Additionally, they have in-ear capacitive detection technology that pauses music when you remove them and plays it when you put them back. Custom-built composite cellulose drivers provide superior sound even when you’re exercising because they’re IPX7 waterproof and use Sweatshield technology. If you’re running low on battery, they fast charge for two hours of playtime in just ten minutes. When fully charged, they offer seven hours of playtime and 28 hours of battery life in the charging case. Wirelessly charge them or plug them in via USB-C, use Google Assistant or Siri voice control, and enjoy simple touch control. Furthermore, you can use one earbud at a time if you prefer, and they offer all-in-one volume control. With a secure and ergonomic fit, they’ll be comfortable for hours.
