Moving on to Bon Iver’s iMi, we had the chance to hear how lush and rich these headphones can sound, with sonorous bass frequencies swelling around verdant vocal harmonies, as industrial beats clatter and fall around the open wide soundstage.On the latter, you can drag a pointer around an equalisation map to adjust the balance towards more bass or treble. There’s no harm in favouring either to get a bit more low-end domination or top-end sparkle although, predictably, going extreme either way makes them pretty unlistenable. At first glance, the Sennheiser Momentum 3 Wireless’ 17-hour battery life sounds rather good, but compare it to the 30 hours offered by Sony's WH-1000XM3 noise-cancelling headphones, and it doesn't seem quite so impressive – especially when you’re paying more for the Sennheiser model.

Bluetooth is complete with aptX Low Latency support for syncing up audio and video (with less than 40 milliseconds of latency) when you’re watching a video or playing a game on your connected device. With ANC switched on and the headphones connected via Bluetooth, battery life is up to an impressive 50 hours. Enough to keep you going for days without a charge, the long-lasting battery life makes all the difference in convenience. Overall, the wide soundstage and detailed sound provided by the Sennheiser Momentum 3 Wireless headphone makes them very adept at voicing your music, no matter how complex. That is mostly the case with performance, too, the HD 450BTs producing a smooth, rich balance that’s enjoyable, not to mention easy to listen to. Whether you’re listening to Frahm’s virtuosic piano playing or satisfying some electro funk impulse, their full-bodied and rounded, yet still plenty lively, delivery will amiably present warm piano keys and sizzling synths alike. Sennheiser are one of the world’s leading headphone manufacturers, making it little wonder that the ACCENTUM headphones sound so impressive. Using in-house speaker drivers, Sennheiser are able to tune the sound to its precise specifications. The 37mm drivers deliver a strong bass and smooth balance that suits a wide variety of music genres.With 42mm transducers, these headphones are made to replicate the "balanced depth and precision of a studio recording". Perhaps the most striking design feature of these noise-canceling headphones is their adjustable headband, crafted from pearl-blasted stainless steel sliders that are held in place by a shiny logo-adorned button. An equalizer within the app means that you can adjust the sound settings, whether you favor a bassier mix or the more natural sound of treble-heavy audio. It’s a nice touch for those who want the ability to truly customize their headphones, but we found that the default EQ setting was the best option for us.

It’s a useful feature, and one that works pretty well – too well, in fact. Sometimes just slightly adjusting the headphones or moving our head was enough to abruptly stop our music. The Sennheiser HD 450BTs aren’t the best sounding noise-cancelling headphones out there for the money. Nor are they the easiest to control on your head.With signature Sennheiser sound, wireless comfort and class-leading battery life, the Sennheiser ACCENTUM are your long-lasting music companion. The headphones come in a bulky, yet attractive fabric carrying case; inside you’ll find a UBS-C charging cable, a USB-C to USB-A adaptor, and a 3.5mm audio cable for when you want to listen with a wired connection.
