The smooth matte black finish gives it a classy, minimalist look. The flexible neckband provides a comfortable fit and stays put during activity.

The intuitive controls handle music and calls without a learning curve. Swapping between paired devices also works seamlessly. The included ear tips offer a customized noise-isolating fit. Extra points for the convenient USB charging rather than fussy battery cases.

Build Quality:

The Sennheiser CX 7.00BT Wireless In-Ear Headphone features durable plastics in the neckband and earbud housings. While not indestructible, they can withstand being tossed in a bag and the rigors of travel. The removable ear tips may wear over time.

Connectivity:

Bluetooth 4.1 ensures reliable wireless performance within range. Pairing worked seamlessly during testing. Range could be limited compared to more advanced Bluetooth versions however. The aptX codec makes music sound incredible despite the wireless connection.
