If headphones are intrinsically a vogue merchandise, the HD 450SE are a staple you’ll be able to put on with something. Recognisably Sennheiser, they provide the identical uncluttered profile and construct high quality because the model’s cheaper HD 350BT. The earcups are fairly padded, and the scarf sufficiently cushioned.

Manual controls on Sennheiser HD 450SE

I’m in two minds about this. There aren’t any secret swipes and wipes to be taught, however the ensuing button fest is a bit inelegant.

The much less apparent characteristic attraction is Sennheiser’s Sensible Management app, required to entry particular audio presets or the customisable EQ. The app additionally reveals present battery standing.

Battery life is spectacular, at 30 hours. I discovered I may simply handle a few days between prices.

Sound High quality

  • Easy and refined
  • Some lack of treble element
  • Sound Examine EQ mode

If there’s one phrase that sums up the HD 450SE, it’s stability. With no EQ utilized, these Sennheisers current every thing with a fair hand. They don’t draw back from deep bass, however they by no means sound overly booming. Dialogue readability is nice, with zero sibilance.

The languid piano, vocals and harmonies of Tears for Fears’ Rivers of Mercy ebb and circulation, exhibiting air and rhythm, whereas Explosions within the Sky’s Wilderness drops deep, confirming an honest bass extension, all with out comprising some sharp, synthy jangles.

If there’s a difficulty, it’s that this sense of equilibrium can lead to tracks congealing, and an absence of dynamics and scale. Nonetheless, given these headphone’s higher finances price ticket, we’ll reduce them some slack, and there’s loads of scope to tweak.

The Sennheiser Sensible Management app has presets for Rock, Pop, Dance, Hip Hop, Classical and Film selectable underneath an Equalizer banner. There’s additionally a devoted Podcast mode.

Utilizing Sennheiser’s Sound Examine mode, you’ll be able to even create a personalised listening expertise, successfully producing a library of EQ presets on your favorite genres.

The HD 450SE do a very good job with small-screen video catch-up. I by no means felt I used to be lacking out on the cinematic motion of Picard (Prime Video, Collection 2). When the Borg got down to assimilate the Stargazer, there’s a deep ominous rumble, and the soundtrack has tangible widescreen width.

I’ve some reservations in regards to the high quality of the noise cancellation right here, although. It really works effectively sufficient in terms of combating normal background banter, nevertheless it isn’t as sonically isolating as the very best ANC, as skilled on the higher Sony or Bose headphones. However then Sennheiser is working to a extra reasonably priced worth.
