They sit perfectly without hurting my ears

The Sennheiser CX True Wireless is a versatile, reasonably priced pair of true wireless earbuds. It doesn't excel at any one thing spectacularly, but it reliably checks most of the boxes you'd want in a low-to-mid-range product.

Thanks to the inclusion of the Ear Fins, the Sennheiser CX Sport sits extremely well and securely in the ear, while delivering clear and rich sound with no annoying after-effects. This is an excellent feature that will certainly go down well with those looking for the best in mobile use.

good design with a large selection of accessories to fit all and quickly charges but holds it charge well

Great fit, amazing sound and most importantly- people sitting next to me cant hear the music!!

I have had a few sets of Sennheis head phones over the years and have loved them all. These are perfect for working or jogging when you want to listen to your favorites and have the ability to answer phone if needed

It's hard to expect top-level audio quality while you're walking down a busy city street, or when you're jogging in the woods. And it's just as hard to design audio equipment built for those conditions. The selling point of sports headphones is their highly portable design.

They stay in your ears. And for wireless earphones, they sound incredible in every genre. I have nothing negative to say about the CX Sport. In my humble opinion, they're the best value for money wireless sports headphones on the market.

If you are a sports lover and a Sennheiser lover, then this is the wireless earphones to get. Fitness enthusiasts can enjoy the bright audio quality without settling for alternative brands for sweat resistance.
