Sennheiser CX 150BT Wireless Earbuds

The Sennheiser CX 150BT are lightweight in-ear wireless earbuds weighing 13g. They connect via Bluetooth 5.0 and support SBC and AAC codecs for audio streaming. A three-button remote handles playback, volume and calls. The package includes four ear adapter sizes (XS/S/M/L) and a USB-C charging cable.

Commuters and casual listeners wanting

These suit users who value simple controls, a secure canal fit and the ability to stay paired with two devices at once. Buyers who need active noise cancellation or aptX codec support should look elsewhere. The 10-hour battery life covers a workday but not multi-day trips without recharging. No water-resistance rating is specified for sports use.

10-hour battery with USB-C charging

The battery delivers up to 10 hours of playback using the SBC codec at moderate volumes. A full charge restores capacity quickly over the USB-C port. At high output levels the 28-ohm drivers may reach their 0.5% THD limit earlier. The 17Hz-20KHz frequency response covers the audible range for music and podcasts.

Questions about this item

Does the USB-C charging cable in the box require a separate power adapter to recharge the earbuds?

Yes, the included USB-C cable connects to any standard USB power source you already own, such as a phone charger or computer port, to deliver the 10-hour operating time.

Will Bluetooth 5.0 multi-connectivity let me stay paired to my older phone and laptop at the same time?

The earbuds support simultaneous pairing with two devices, so an older phone and laptop can both stay connected and you switch between them without re-pairing.

How do I confirm the three-button remote is communicating properly after the first pairing?

Use the remote to play music, adjust volume and answer a test call; correct responses show the HSP, HFP and AVRCP profiles are active.
