    Overview

    The quintessential Marshall headphone, the Monitor, delivers studio quality Hi-Fi sound all while sporting a vintage look. While the look of Marshall headphones may not have evolved drastically over the years, their sound has only gotten better. Custom-made low-distortion 40 millimetre drivers reproduce the sounds and feel of live performances. Embrace truly clear, detailed, and balanced audio, sounding all the better thanks to the over-ear design.

    Embrace the freedom of wireless audio with Bluetooth aptX, granting you over 30 hours of playback. For times when you cannot use Bluetooth, a provided 3.5 millimetre cable keeps your music flowing. A brass, multidirectional control knob on the headphones allows you to not only control your audio but to also answer, end or reject calls. And for easy travel and storage, these Monitor headphones make use of a foldable design, allowing them to collapse inwards.
    Bluetooth Connectivity

    Wires are out, wireless is in. The simple Bluetooth connectivity in this unit makes it easy to enjoy your favourite music wirelessly.

    Passive Noise-Cancelling

    Passive noise cancelling is achieved purely through the design of these headphones. A cushioned ear piece blocks outside noise; so that you can spend more time listening to music and less time listening to noise.

    Extra 3.5mm Socket

    Music tends to bring people together, and with an extra 3.5mm socket on this unit, you can share your favourite songs with friends, watch something together or audibly prank them.

    Over-Ear Design

    The over-ear design of these headphones blocks external noise and allows you to immerse yourself in your music. Over-ear headphones have more physical space for the drivers that power your music, which generally gives you more natural sounds and greater bass.

    Great headset
    Bought my headset at an airport and thought it was the perfect gear for traveling. Which it is. But the hinges although said to be heavy duty, doesn't survive minor accidents as being left unfolded and left in seat. Came back to find one of the hinges loose and jumped off the hinges which are just two tiny screws that I could put the headsetclock back into but remaind loose as hell and with no way to fix it I have to say im about disappointed by the durability

    Monitor Bluetooth
    Negative: A little bit tight on my ears, it gets uncomfortable after long continuous use (about 2 hours) on the head. Positive: Very long battery time Good sound quality Very good Marshall service. My headphone broke - could not be charged anymore - after more than two years continuous use. Marshal replaced the headphone for a new one for free in about a week. Excellent service!

    Good sound quality, uncomfortable to wear
    Great customer service. Good sound quality. The device underperformed on the volume. These should be advertised as on-ear not over-ear headphones. Tried to test the spl with cardboard and a mic only received 77db. Uncomfortable to wear after 30 minutes. I ended up returning.
