Sound quality is the headline strength — owners repeatedly call it the best-sounding wireless headphone in its price bracket, often preferring it over Sony WH-1000XM4/XM5, Bose QuietComfort, and even AirPods Max for clarity, bass, and soundstage
Battery life holds up for years of daily use with minimal degradation, charges fast, and the user-replaceable battery is praised as a rare feature at this price
Great value for the price, especially now that it's discounted since the Momentum 5 launched — described as unbeatable price-to-performance and a steal around $150-200
Owners complain about
ANC is consistently rated weaker than Sony (WH-1000XM3/4/5/6) and Bose competitors — usable for daily commuting but inadequate on planes for some owners

Software/app bugs and Bluetooth connectivity issues — dropped connections, multipoint pairing problems, and headphones randomly turning on/off or losing pairing

Anyone sensitive to strong headphone clamp force

Skip it if
Frequent flyers who need best-in-class ANC, since Sony and Bose noticeably outperform it

What Momentum 4 Wireless owners think
Owners overwhelmingly praise the Momentum 4 Wireless for sound quality, calling it the best-sounding headphone in its price range and frequently preferring it to Sony's XM4/XM5, Bose QuietComfort, and AirPods Max, backed by strong multi-year battery life, comfortable long-session fit, and standout value now that the Momentum 5 has arrived. A meaningful minority pushes back hard, though: ANC is consistently rated behind Sony and Bose, and a recurring cluster of owners report durability failures — fraying headband fabric, cracking parts, buggy firmware, unreliable touch controls, and units that stop working after exposure to sweat or rain, sometimes prompting warranty repairs or returns. The net consensus is a headphone bought primarily for its audio quality that some owners find undermined by build-quality and software reliability issues over time.
