Sound signature and driver

Sennheiser Sport True Wireless Earbuds are built around a 7 mm TrueResponse dynamic driver that delivers the brand's signature sound with full bass. The frequency response reaches from 5 Hz to 21 kHz, covering deep lows and detailed highs for music and calls alike.

Fit-sensitive listeners and cable-free users

The in-ear design includes multiple tip sizes so wearers can secure a proper seal; without that seal, sound quality and call clarity drop noticeably. Buyers who dislike inserting tips into the ear canal or who need over-ear stability for vigorous exercise should look at a different style.

TrueResponse 7 mm driver

The single specification that decides suitability is the 7 mm TrueResponse transducer, which defines the earbuds' bass depth, clarity and overall tonal balance. If that driver profile matches the listener's preference, the buds fit the purpose; if a different driver character is required, another model is needed.
