Sennheiser HD 250BT Bluetooth Headphones (Black)

The Sennheiser HD 250BT is a wireless on-ear headphone in black, built around 32 mm dynamic drivers in a closed-back, supra-aural design. It is the straightforward end of the Sennheiser range: Bluetooth listening with a long battery life, a built-in microphone for calls, and sound tuning handled by the same transducer approach used across the company’s headphones. A 25-hour battery, USB-C charging and support for the Sennheiser Smart Control app round out a specification aimed at everyday listening rather than feature checklists.

Sound and codecs

The closed-back 32 mm drivers deliver a rated frequency response of 20 Hz to 22,000 Hz, with sound pressure level of 110 dB and total harmonic distortion below 0.3 percent at 1 kHz. Codec support is broader than most headphones at this level: alongside SBC and AAC, the HD 250BT supports aptX and aptX Low Latency, the latter reducing audio delay when watching video on compatible devices so dialogue stays in step with the picture. The Smart Control app for iOS and Android adds an equaliser for adjusting the balance to taste, along with settings management and firmware updates.

Battery, calls and controls

The built-in lithium-polymer battery is rated at 190 mAh and gives up to 25 hours of music playback via SBC, which covers a working week of commuting for most listeners between charges. Charging is over USB-C and takes up to 3 hours for a full charge. A single built-in ECM microphone with an omnidirectional pickup pattern and a 100 Hz to 10,000 Hz response handles calls and voice assistants, and on-ear controls manage playback, volume and calls without reaching for the phone. Bluetooth 5.0 provides the wireless link to phones, tablets and computers.

Fit and everyday use

Supra-aural earcups sit on the ear rather than around it, which keeps the HD 250BT compact and light at 125 g and makes it easy to carry for travel, the office or the commute. The closed-back construction gives a degree of passive isolation from surrounding noise, useful on trains and in shared workspaces, though this is not an active noise cancelling model and should not be bought as one. The black finish and simple headband design keep the styling understated. In the box are the headphones, a USB-C charging cable and the quick and safety guides.

For listeners who want Sennheiser sound, proper aptX support and a battery that lasts the week in a light on-ear frame, the HD 250BT covers the essentials without complication.
