MOMENTUM 4 remains an older, discounted option for long battery life and sound value. It is not the current flagship: MOMENTUM 5 exists. The discount is useful only if the fit, noise reduction and call performance meet your needs; a long battery specification does not compensate for a poor seal with your glasses.

Independent evidence
What reviewers and owners actually found.
RTINGS found roughly 62 hours of battery life but weaker deep-rumble attenuation and microphone handling than stronger peers; glasses can also change the seal. SoundGuys’ review, first published in 2023 and updated in 2025, likewise favored sound and battery over top-tier ANC. Its quoted prices are historical. A long-term Reddit discussion includes favorable fit, sound and touch-control experiences, but those self-selected opinions do not establish superiority or reliability. MOMENTUM 5 is the successor, so M4 is a discount decision rather than the latest-model choice.
