Momentum 4 Wireless

45%of 469 owners recommend
45% recommend · 27% neutral · 28% don't
Owners praise
  • 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
  • Build quality and durability complaints, the fabric headband covering comes loose or peels within months, glue fails after about a year, and units crack or break under normal use
  • Software/app bugs and Bluetooth connectivity issues, dropped connections, multipoint pairing problems, and headphones randomly turning on/off or losing pairing

What Sennheiser HD 620S owners say

“Just got my 620s yesterday, I like it, which is saying a lot for a closed back. I think it’s easily one of the best closed back headphones not only in the price range, just in general.”
— MoonWun_ on Reddit
“Crazy enough, the HD800s and the HD620s share the top spot in my endgame headphones. And the price difference is over €1,000. I just can’t believe what the HD620s deliver for €279.”
— No-Desk-1808 on Reddit
“I think technically the 620s but the design of the ear cups means they have this bit that protrudes into the ear cups (I think the anchor for the headband) and it’s quite uncomfortable (at least for me).”
