Sound Quality

With a brand name like this you'd expect great-sounding audio, and we're not disappointed

Audio fidelity can be an extremely subjective subject, and even well-trained ears can disagree on a system's merits. But after spending a few weeks listening to all variety of music, media, and even making calls with the Monitor Bluetooth headphones, we feel pretty confident saying that these sound exceptionally nice.

Bass notes are rich and satisfying without overwhelming or causing distortion, while treble is clear and precise without sounding tinny or artificially emphasized. Mids might benefit from a little greater presence, but we're still very happy with the overall balance here.

On phone calls, remote parties sounded just fine, and if anything the high quality of these headphones only called more attention to the lossy compression of regular voice calls – but that's hardly something we're going to hold against Marshall Headphones. The microphone on the headphones works about as well as we'd expect, but it's clear that it's trading unobtrusive placement for quality – we were told we sounded a bit dark and harsh, but didn't have any problems coming through intelligibly.

Battery Life

Even with infrequent charges, battery life should never be a bit issue

Big ear-covering headphones have plenty of benefits over tiny little earbuds, and high on that list is room sufficient to fit in a good-sized battery. During our testing period, recharging the Monitor Bluetooth headphones after every few listening sessions, we never ran into danger of running out of juice.

According to the manufacturer, the headphones should be capable of more than 30 hours of usage, but that's probably under ideal conditions with limited volume levels. Still, you should have no problems going north of 20, thanks to the straightforward nature of this hardware, without battery-draining extras like active noise cancellation.


The Marshall Headphones Monitor Bluetooth succeeds in part because of knowing exactly what it wants to be: a no-nonsense, straightforward pair of really high quality wireless headphones. Audio sounds clean and precise, but more than that the headphones look pretty cool, feel nice and solid, and are quite comfortable to wear.

What problems we have with the pair are relatively minor: the control knob can be a little finicky to push in the right direction, but it still feels responsive and well made. And while we're less than totally convinced as to the long-term durability of the exposed wire coils, it's hard to deny that they look pretty neat.

No, you don't get a ton of extra features here, but we're not sure we'd need them all in the first place. And even things we really like, such as active noise cancellation, are adequately addressed thanks to a snug-fitting design that helps keep ambient noise out.

Maybe the biggest obstacle to overcome in deciding to pick up the Monitor Bluetooth headphones is the price, and at $250, these are definitely on the steeper side of things. Part of that is paying for style, but if you like this classic rock-and-roll look, and you've got the money to spare, you should be seriously satisfied with what these headphones have to offer.
