Monitor III A.N.C.

"The sound is amazing even though there is no other codecs apart from SBS and AAc."

Users overwhelmingly praise the sound quality as exceptionally clear, detailed, and natural, often deeming it superior to other high-end brands.

"Add to that how beautiful they are and how comfortable they feel, the Marshall Monitor 3 are the best purchase I made in a long time."

The headphones are frequently described as comfortable for extended wear.

"I only tried them in public transport once (got them for like a week now) and with using AAC I already notice a faulty BT connection 3 times where is loses connection and crackles."

The battery life is highlighted as a significant positive, with one user mentioning an impressive 70 hours.

"I'm getting a refund as the button broke thru normal use after only 3 months and the mechanical joystick/button was one of the reasons I was drawn to them."

While the overall aesthetic and build are praised, a critical failure of the button mechanism in one instance significantly lowers the score.

"But then I've seen that aptx is the default for android in 2025 and SBC is way outdated."

The limited codec support (SBC/AAC only) and instances of faulty Bluetooth connections with crackling are major drawbacks for users, especially Android users.

"The Marshall Monitor III headphones are tuned very tastefully for their target audience, again, focusing primarily on the Rock music genre above all else."

The sound quality is generally praised as great and pleasing, particularly for rock music, with good clarity and instrument separation, though some find the high mids a bit much without EQ.

"The earpad cushions feel soft like pillows, and I feel virtually zero pressure from the clamping force."

Users consistently praise the comfort, highlighting soft earcups, lightweight design, and lack of pressure points, making them suitable for extended wear.

"They offer an incredible 70 hours of listening with ANC on or up to 100 hours with ANC off."

The battery life is universally lauded as exceptional and class-leading, with users reporting incredibly long playback times that significantly outperform competitors.

"Build quality is amazing, earcups can fully articulate, and it’s got metal headbands which should put to rest any concerns about the headband breaking."

The build quality is frequently described as durable, rugged, and premium, with the use of metal and thoughtful design elements contributing to a long-lasting feel.

"In terms of mic pickup, The Monitor III is one of the better performing ones."

Microphone quality is considered decent, performing well in blocking background noise and wind, though clarity can be an issue and it's not recommended for critical calls.

"The headphones include support for Bluetooth LE Audio and Auracast, which futureproofs them to a small degree."

The headphones offer modern features like Auracast and a customizable M button, but lack high-res audio codecs and some advanced features found in competitors, with a USB-C only port being a minor inconvenience.

"Marshall headphones have better sound quality and a wider soundstage. When listening to the same songs, Bose flattens the soundstage and sometimes makes the bass overly powerful."

Opinions are divided, with some praising the design and solid feel, while others criticize the build as cheap, flimsy plastic, especially given the price point.

"Works so good!! I also have installed Viper4android equalizer. Its sick. Also its sick microphone. Crisp sound."

A few users mention the microphone quality positively, describing it as crisp and good for calls, but it's not a frequently discussed aspect.

"Monitor III's multi-connectivity is not that seamless. The app loads a lot too."

While praised for physical buttons and multipoint connectivity, issues with the app, lack of advanced codecs, and the absence of a native 3.5mm jack are noted drawbacks.
