PSB M4U TWM Headphones

Most earbuds use dynamic drivers, but the M4U TWM uses a dual-driver system combining a magneto-static high-frequency driver with a planar dynamic mid/bass driver. This design provides significantly lower distortion and a more precise, natural soundstage that mimics the experience of listening to high-end speakers.

Yes, these earbuds integrate Audiodo™ technology, which allows you to perform a hearing test through the companion app. It then creates a personalized audio profile that compensates for your specific hearing sensitivities, ensuring you hear every detail in your music.

Absolutely. They carry an IP65 rating, which means they are fully protected against dust ingress and can withstand low-pressure water jets, such as sweat or rain. They are built to handle active lifestyles without issue.

RoomFeel™ is PSB's proprietary technology designed to emulate the open, natural sound of a high-quality listening room. It prevents the 'in-your-head' feeling common with many in-ear monitors, making the audio sound more spacious and less fatiguing during long listening sessions.

Yes, they support aptX™ Adaptive Bluetooth streaming. This codec dynamically adjusts the bitrate to provide high-resolution audio quality while maintaining a stable connection, provided your source device also supports the aptX Adaptive standard.

The M4U TWM uses physical buttons rather than touch-sensitive surfaces. This is a deliberate choice to prevent accidental inputs when adjusting the fit or wiping away sweat, offering more reliable and tactile control during exercise or movement.
