Wireless in-ear headphones for daily use

The Sennheiser CX 150BT White uses Bluetooth 5.0 for a stable wireless link to phones and tablets. Canal-type ear tips seal the ear canal for passive isolation in noisy environments. At 13 g the neckband sits lightly during commutes or desk work. Four ear adapter sizes (XS/S/M/L) let each listener find a secure fit.

Ten-hour battery with USB-C charging

A single charge delivers up to 10 hours of playback when streaming over the SBC codec. The USB-C port replenishes the cell without a proprietary cable. SBC and AAC codecs cover the majority of mobile sources. Frequency response spans 17 Hz to 20 kHz at -10 dB with 0.5 % THD measured at 1 kHz and 100 dB SPL. The 28 ohm impedance suits portable device output stages.

Multi-point pairing and inline controls

Bluetooth 5.0 supports simultaneous connection to two devices so calls on one source pause media on the other. A three-button remote on the cable handles volume, track skip and voice-assistant activation without touching the phone. Supported profiles include A2DP, AVRCP, HSP and HFP for audio and telephony. The package supplies the earphones, ear adapters, a USB-C charging cable, a quick guide and a safety guide.

Questions about this item

Will the Bluetooth 5.0 connection stay stable if I pair these with a laptop that only has Bluetooth 5.0?

Yes, Bluetooth 5.0 is backward-compatible with earlier versions, so the CX 150BT will pair and maintain a stable link with any laptop that supports Bluetooth 5.0 or older.

How can I confirm the CX 150BT is delivering the specified 17Hz-20KHz frequency response and 0.5% THD after pairing?

Play a high-resolution test track covering the full 17Hz-20KHz range; clean bass down to 17 Hz and clear treble to 20 kHz without audible distortion indicates the drivers are performing within the 0.5% THD spec.

Which items come in the box with the CX 150BT White, and what must I purchase separately to start using them?

The box includes the earphones, four ear-tip sizes (XS/S/M/L), a USB-C charging cable, a quick guide and a safety guide; only a USB power source (charger or powered port) is needed separately to charge the battery.
