Sennheiser HD 350BT Wireless Foldable Headphone, White

Product Information

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. 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. With 42mm transducers, these headphones are made to replicate the "balanced depth and precision of a studio recording".

The 37mm drivers deliver a strong bass and smooth balance that suits a wide variety of music genres.

The accompanying vocal and trebly synths, which sit just on the peripherary of the Sennheiser’s centre-stage spotlight, carry decent detail and as much impetus too. By comparison, though, the AKGs and similarly priced Philips PH805s do greater justice to the production by surfacing greater texture and dynamic variation. Verdict 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. Their tonality is a little skewed towards the bottom end, sacrificing the midrange clarity that more neutral rivals, such as the AKG N60NCs, are capable of. That may not play into the hands of every music fan, but those who like electric guitars to sound weighty and basslines beefy will find favour in the Sennheiser’s modest bias.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. 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. 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.
