About the Sennheiser Momentum Free
Wireless headphones with a sound pedigree
Wireless headphones with a sound pedigree
Sennheiser made this version of their popular Momentum wireless earbuds (also known as the HD 1) for those who prefer the "wrap around cord" style over a neckband. They feature the same energetic sound that's rich in musical detail. Tiny, powerful dynamic drivers dish out lively sound that's nicely balanced. Each earbud features an acoustic "tunnel" made of stainless steel that carries the sound from the driver directly into your ear canal.
Looks good on the go
These headphones are part of Sennheiser's fashion-conscious Momentum product line — so they feature some nice design touches. The cord connecting the earbuds is low-key and subtle. It's nicely balanced against the flashier, mirrored-chrome earpieces.
Stay in control
The design isn't just about good looks — there's some neat functionality, too. If you get a phone call, you can answer it through the headphones' built-in mic. There is a three-button remote for music and phone calls, so you should rarely have to fish your phone out of your bag or pocket.
Comfortable ear tips that stay in place
Soft, flexible ear tips are included. You can choose from four different sizes, so you should be able to find the right fit. They help keep the headphones securely in place while keeping external sound out.
