Many modern true-wireless earbuds come inside a charging case that can recharge wirelessly, just by laying it on a Qi charging pad. The HolyHigh EA2 true-wireless earbuds come inside a case that is, itself, a Qi charging pad! It's true: Flip it over and lay your phone on it for easy on-the-go wireless charging.
So, in a way, it feels like you're buying a portable Qi power bank that just happens to have earbuds inside. And that power bank recharges via USB-C and has a Type-A USB output as well. If you use it just to keep the earbuds powered, the 5,000-mAh battery can net you a whopping 240 hours of total playtime, according to HolyHigh.
The earbuds themselves: Pipe design, noise-isolating eartips, IPX5-rated sweatproof and waterproof. I'm listening to them right now; the sound quality is decent given the price, maybe a little flat overall, lacking in detail but definitely good enough for the gym. As with all such earbuds, getting a good inner-ear seal is key.
Oh, and speaking of price: Just $33.49 when you clip the on-page $5-off coupon and then apply promo code TYDZD2RD at checkout. That's less than what you'd pay for countless earbuds that don't have a super-versatile charging case.
