About the Klipsch S1 True Wireless

Lightweight, value-packed earbuds from Klipsch

Klipsch dove headfirst into the truly wireless trend last year with their T5 True Wireless earbuds — one of our top-selling headphones. The sweat-proof S1 True Wireless earbuds sport a lighter, streamlined design, but retain many of the performance features of that popular T5 model. For example, Bluetooth 5.0 is on board, which is the latest and greatest version of the popular wireless technology.

Lightweight, value-packed earbuds from Klipsch

Klipsch dove headfirst into the truly wireless trend last year with their T5 True Wireless earbuds — one of our top-selling headphones. The sweat-proof S1 True Wireless earbuds sport a lighter, streamlined design, but retain many of the performance features of that popular T5 model. For example, Bluetooth 5.0 is on board, which is the latest and greatest version of the popular wireless technology.

That means a stronger, more stable connection for playing music wirelessly from your phone. And there are absolutely no wires to get in your way as you listen. (These headphones are also available with a wireless Qi charging pad.)

Hefty bass and slim rechargeable case

These headphones offer about five hours of battery life, and the charging case banks about 16 hours of power for recharging. The S1's case is slimmer than than the T5's case, but doesn't have the cool Zippo® design. Still, this case might be functionally better for fitting into a gym bag.

And Klipsch designed this model for the gym crowd. 5mm drivers deliver a punchy, bass-forward sound that is tuned to keep you in rhythm while you run and workout. In fact, if you crave a lot of low-end in general, you may actually prefer the S1's sound versus the T5. That model has a well-rounded sound designed more for focused listening, while these headphones bring the bass. 

Soft oval ear tips for patented comfort

Klipsch includes two sizes of their patented oval ear tips. These soft silicone earbud covers slide in easily to keep the earbuds stable and secure while you move. I find they avoid pressure points and create one of the best seals out there — crucial for getting solid bass response.

On my recent tour of Klipsch HQ, I saw firsthand that they didn't just stumble onto this design. They showed me several tackle-boxes full of rubber-ish molds of actual people's ear canals. In these molds, they noticed an oval cross section in each mold – no matter the size.

Microphones: Each ear bud features two microphones for better voice clarity and to reduce environmental noise.
