Product Description
Sennheiser CX 7.00BT — Compact Bluetooth In‑Ear with aptX
The Sennheiser CX 7.00BT blends lightweight ergonomics, reliable wireless connectivity and detailed sound for everyday listening. Designed around a comfortable neckband form factor, these in‑ear headphones deliver crisp highs, controlled mids and enhanced bass response thanks to Qualcomm aptX support and Sennheiser tuning. With Bluetooth 4.1 compatibility, NFC one‑touch pairing and support for HFP, A2DP and AVRCP profiles, the CX 7.00BT works smoothly with smartphones, tablets and computers.
Battery life is a strong selling point: a 170 mAh built‑in Li‑Po cell provides up to 10 hours of playback on a single 1.5‑hour charge. The micro‑USB port charges the headset while letting you use the USB connection as an audio device on compatible computers. A clear LED and voice prompts keep you informed about pairing, connection and remaining battery time.
Controls are simple and tactile: play/pause/phone controls, volume and track skip buttons are placed for quick access, and advanced call handling features include answer/end, reject, hold, redial and mute. The on‑board microphone supports hands‑free calling and voice dialing on HFP‑capable phones. If you prefer wired USB audio, the headset operates as a USB audio device for direct playback and charging.
Ergonomics and maintenance are practical: multiple silicone ear adapters (XS, S, L) help achieve a secure seal and passive isolation; the neckband construction keeps the headset stable during movement. The package includes a transport pouch and a micro‑USB cable. For care, avoid liquids, clean with a soft dry cloth, and store the headset in its pouch when not in use. Battery replacement and internal servicing should be handled by authorized service centers to preserve warranty.
Whether you want aptX wireless fidelity for music, reliable hands‑free calling or a convenient USB audio option, the CX 7.00BT offers versatile features in a compact, travel‑friendly design.
