Sennheiser MOMENTUM 5 Wireless vs onn Wireless On-Ear Headphones

The Sennheiser MOMENTUM 5 is the better headphone by a wide margin: adaptive ANC with 8 mics, aptX Lossless and Dolby Atmos spatial audio, a replaceable battery rated up to 57 hours, and a 42 mm driver tuned in Germany. The onn is a basic on-ear with passive isolation only, Bluetooth 5.0, 24 hours of playtime and bass-heavy tuning. Buy the Sennheiser if sound quality, noise canceling and long-term durability matter; buy the onn if you want a light, foldable pair for casual listening and calls and don't need ANC.

  • Choose the Sennheiser MOMENTUM 5 if you want strong adaptive noise canceling, hi-res codecs and a battery you can replace years from now.
  • Choose the onn Wireless On-Ear if you want a light, collapsible pair for podcasts, calls and everyday listening without active noise canceling.

Questions and answers

Which is better for commuting?
The Sennheiser MOMENTUM 5. Its adaptive ANC with 8 mics and automatic wind-noise suppression handle trains, buses and street noise that the onn's passive isolation lets through.
Which lasts longer?
The Sennheiser. It is rated up to 57 hours with ANC on versus 24 hours for the onn, and its battery is replaceable, so it can keep going after the cell wears out.
Is the Sennheiser worth stepping up to?
Yes if you care about sound quality, quiet and call clarity. The onn covers basic wireless listening; the Sennheiser adds ANC, lossless codecs, spatial audio and a far longer-lasting battery.
Which is better for calls?
The Sennheiser. Beamforming mics with Own Voice Detection and call externalization make you sound clearer; the onn has a single built-in mic with no noise handling.
Can I use either wired?
The onn has a 3.5 mm AUX port for wired listening. The Sennheiser MOMENTUM 5 is Bluetooth only, with no wired input listed.
Which is more comfortable for long wear?
The Sennheiser's over-ear cups and low headband pressure suit long sessions better. The onn is lighter at 150 g but presses on the ear, which can ache after a couple of hours.
