About the Sennheiser CX 7.00 BT

Sennheiser sound in a trendy neckband design

Neckband earbuds are popular these days — and our customers have always dug Sennheiser headphones. The CX 7.00 BT in-ear headphones feature a sturdy neckband that stabilizes the earbuds as you move around. Music plays wirelessly, and the sound is all Sennheiser. When I spoke to the company's legendary designer Axel Grell, he told me that the company uses the super-premium models (like their flagship in-ears, the IE 800 S headphones) to inform the design of all of their headphones.
