Overall Sound ProfileFrom the very first listen, the sound is immediately striking: clear, detailed, and well-balanced. The earbuds manage to deliver a natural sound signature that doesn’t overly emphasize any one frequency range, making them incredibly versatile across genres.
When I tested them with acoustic tracks, I was impressed by the clarity and warmth of the vocals and strings. The soundstage felt expansive and the separation between instruments was crisp, which made the listening experience incredibly engaging.For pop and electronic music, the bass was deep but not overpowering.
Sennheiser’s tuning here strikes a good balance between punchy low-end and detailed mids and highs. While the bass wasn’t as thumping as what you might get from a bass-heavy pair of earbuds, it was precise and enjoyable without muddying the rest of the sound.Buy the Sennheiser Momentum 4 TWS here:Dynamic Sound RangeWhat really stood out to me was the dynamic range of these earbuds.

There was no distortion, even at higher volumes, which speaks volumes about the quality of the drivers used in the Momentum True Wireless 4.In a test of high-resolution audio files, I found the sound to be noticeably fuller. Thanks to the Qualcomm S5 Sound Gen 2 processor and aptX Lossless support, I was able to stream lossless 16-bit/44kHz and even 24-bit/48kHz audio (after a chip update) with clarity that rivalled wired options.Noise Cancelling & Sound QualityWhen Noise Cancelling (ANC) is turned on, the sound quality becomes better.
