Customer Ratings & Reviews

The Marshall Monitor III packs quality, convenience, and aesthetic all into these ready-for-travel sound-rich headphones. Unboxing Opening up the package is an experience all its own. The box opens up to reveal a beautiful shell case, soft, textured, yet sturdy, and encased within, surrounded by a red, velvety fabric, are the headphones neatly folded. A magnetic pocket reveals the included cables, one for charging, the other a USB-C to audio jack converter. Construction The headphones themselves are extremely lightweight, made with high quality plastic and ultrasoft ear cushions. Despite their lack of weight and remarkable flexibility, they feel sturdy and rugged. The cushions feel like clouds, they are so soft that I forget I am wearing them, and they create such a good seal around the ear that they play a strong role in the noise-cancelling factor, as well as the spatial soundstage effect. They also work to keep the noise contained –when the headphones are on the ear those around me could not hear what I was listening to, but upon removing them, everyone could hear it quite loudly. One thing I will note about the cushions is that they cause me to sweat in the area that they sit when I wear them for extended periods on warm days. Buttons There are three buttons on the headphones, two of which Marshalls cleverly disguised to blend into the design. The main button is the gold control knob, which functions to turn them on/off, pause/play, answer calls, and more, plus moves directionally to control the volume and skip songs. It is strategically placed on the right back side where the thumb can easily find it. The other two buttons are also in the back, one is the ANC toggle and the other is the customizable M-button. Automatic Pause/Play The headphones come with a feature that allows them to sense when you remove them and when you put them back on. They will pause within a few seconds of them coming off and restart once they’re back on your head. I do wish the pause had less delay, it takes several seconds before the sound stops, but most headphones I have had don’t have this feature, so I am still grateful for it. Battery Life The battery life lives up to its promise of 70 hours. I have not come close to draining it yet and it would take me weeks at my current rate before my next charge. It also charges incredibly fast for that amount of longevity. Bluetooth The Bluetooth LE connects in a snap and features a 30-foot range that lives up to that promise and somewhat surpasses it. The low energy advanced Bluetooth technology is part of what helps the Monitor III have such a long battery life. The Sound The sound is absolutely phenomenal! I listen to a variety of genres and these headphones blew me away with each and every genre. It has been a while since I have had headphones with such richness and depth coupled with clarity and crispness. Each note comes through beautifully and undiluted presenting the original intended harmony. It is truly the euphonious experience that audiophiles look for. *ANC* The active noise cancellation mode does a great job at reducing ambient noise. The three levels actually do what is expected, with the lowest ANC level still allowing ambient sound at a reduced volume and the highest level almost completely removing it. Sometimes I wore the headphones without playing anything on them just to concentrate on my work with my kids around. I could still hear them faintly, which helped keep me from worrying what they were up to. When music is playing though, I could not hear any ambient sound with ANC on at 100%. *Transparency* The transparency mode, which also comes in three levels, is just as effective. It allows ambient sound in, and I can clearly hear everything going on around me. It works well with podcasts and streaming, but with music it is not always effective. It depends on the song as some just overshadow any ambient sound and I cannot hear my surroundings whatsoever. *Soundstage* I found the Soundstage feature delightful. It gives the option to choose a room size and a percentage. It accurately gives a spatial experience as if sound were bouncing off walls and creating an echo-like reverberation. It also adds depth to the sound and helps when with podcasts as it brings the voice out more clearly. Mic The microphone works perfectly well. I tested it during a phone call and recipient said they heard me loud and crystal clear. I also tried voice recording, and it was also good as long as I did not talk too low. When I spoke in a low volume the sound cut in and out. The Marshall App The app by Marshall is sweet and simple. It has everything necessary in an intuitive layout. The EQ has the option to have the second preset set to one of 5 options or a personally customized one. Besides that, there is the soundstage, noise control, and a few customizations one can choose, including battery conservation customization. Storing It Storing it back in the case neatly took me some practice, but I finally got it down. I was initially extra careful because I was afraid to bend them the wrong way, but they can really take the maneuvering without issue. The best thing to do is to take a photo of the way they came initially to avoid unnecessary fumbling (I had a picture and did not think to try this until days of struggling). I will advise to be wary around the joints as I have pinched my finger and skin on several occasions, both while storing and opening, and it is quite painful. Overall I am thoroughly impressed with Marshalls Monitor III. I can get lost immersed in my music for days with these. The construction, the quality, the features all serve to elevate the experience and besides the pinching and slow pause, I really have found nothing to detract for these headphones. I highly recommend it for the music lovers and audiophiles out there.

The Marshall Monitor III have an appearance that is unmistakably Marshall, even if you somehow missed the gold script “Marshall” adorning each ear cup and the hard-side, velvet lined carrying case. Don’t let its vintage look fool you. The Marshall Monitor III are thoroughly modern with amenities one expects from premium headphones. Some of these are: Superb sound quality at any volume. With ANC activated, there’s no need to crank the volume to enjoy the subtle nuances of what you’re listening to. There is also an “Adaptive Loudness” toggle that varies volume and “tonal balance” based on ambient noise. Convenient controls. The control knob delivers access to control of your headphones, including power, play/pause/skip and volume control. I have no intention of using the Marshall Monitor III for phone calls and did not test that functionality. Great battery life. 70 hrs with ANC, 100 without. The battery is charged via USB-C and took a little more than an hour to achieve full charge out of the box. With a rated 70 hrs while using ANC, the Marshall Monitor III are still going strong even after a few days of use. Good noise cancellation. It’s not like I’m in an isolation booth, but the Marshall Monitor III do a good job tuning out the world around me at home, the office, or working around the house. In-app 5-band EQ with six selectable sound profiles including one customizable slot. Two profiles can be designated for use with the “M” button. No app required. The app has a battery preservation setting that limits maximum charge to extend battery lifespan. I’ve been using similar settings in my notebook computers for years with excellent results. There is an included USB-C to 3.5mm audio cord that allows corded connection to your audio sources. It’s a welcome inclusion that brings sound from my non-Bluetooth devices within reach. Folding the Marshall Monitor III and storing them in the included hard-side case is proof that engineering matters. The hinges move freely, feel durable, and nothing is mechanically stressed when folded for storage and transport. There has to be a negative comment, right? While working outdoors in sunlight, I learned that these headphones trap heat and moisture. In the right environment, the Marshall Monitor III are comfortable for hours at a time. Mine will be for use indoors only. Conclusion: The Marshall Monitor III sound great, are comfortable, and definitely worth a look if you’re in the market for quality premium headphones that tick all the boxes.

Marathon battery life, vintage design, excellent sound quality. The only downside is that the headphone cups trap heat and sweat.

Marshall has done it again. I am familiar with Marshall products as I have a pair of the in the ear type Bluetooth earbuds and I have the small Emberton Bluetooth speaker, both of which I enjoy and use frequently. The app has been updated and has a little more customization to it. I really like that you can set your own custom EQ now or bypass it and use either the Bluetooth device or a third party app. First, the headphones are top notch quality. The zip around case has the leather texture we have come to know on Marshall products. Inside has a velvet like material that cups and cushions the headphones. The headphones also have the leather material and the cushions are plush and super comfy. They do get hot if you are moving around, however. The band is also very comfy but I was worried at first they would be stiff. Pairing is easy, the gold solid button puts into pairing mode, open your Bluetooth, select Monitor III and the app picks the product right up. It will do a firmware update and you are off and running. I set up a custom rock EQ and starting streaming from iHeart. Again, like previous reviews, if you don't have the paid setting, the quality is not as loud and good but these still sound amazing. I moved on to stored music and they really start to shine. I had to turn them down one notch as the quality of the stream improved. Now, here is where these headphones almost became my favorite. I used a third party EQ/amp and the sound I was looking for came right through and the fullness/loudness came full circle. I now played my music at 75% volume and these things just crunch and sound awesome! Bass is a little (very little) lacking but then again, I wasn't looking for rap style bass. These are super light to wear, you won't get fatigued wearing them and they stay on pretty good when you are headbanging LOL. I love the old school look (wires showing), quality is top notch and the sound is pure Marshall! Almost forgot, the ANC is right up there with the best. I would not say perfect but you do not get that sucked out feeling. I had to test them because I did not think it was working, but I was wrong. Finally, the other button on the right side can be customized to your liking. I used it to switch EQ settings and they are built right into the hinge of the can portion. Like I said, very high quality and I highly recommend!
