Marshall Minor IV

Name: Marshall Minor IV
Brand: Marshall
SKU: 32138

Manufacturer: Marshall

The Marshall Minor IV are true wireless earbuds that combine the brand's recognizable aesthetic with a practical, cable-free design. Weighing just 14.78 g, they sit as standard earbud-style units without neckband or wingtips, and the included travel bag adds a degree of everyday convenience. A rechargeable charging case extends total listening time well beyond what the earbuds hold on their own, and wireless charging support means topping up requires no cable at all.

On the connectivity side, the Minor IV runs on Bluetooth 5.3 with LE Audio support and a maximum wireless range of 10 m, while multipoint pairing allows simultaneous connection to two devices. The 12 mm drivers cover a frequency range of 20 Hz to 20,000 Hz at 32 Ohms impedance. For calls and voice use, two microphones handle input with noise-canceling mic processing, and features such as mute, voice prompts, fast charging, and a find-device function round out the practical side of the package.

Pros

Wireless charging support means the case can be topped up without needing to find a cable
Multipoint connectivity allows simultaneous pairing with two devices at once
A find device feature helps locate misplaced earbuds
Fast charging reduces downtime when the battery runs low
The charging case extends total listening time to 30 hours combined, well beyond the earbuds alone
A travel bag is included, adding a practical carrying option out of the box

Cons

No active noise cancellation or passive noise isolation, leaving the listener fully exposed to ambient sound
Bluetooth range is limited to 10 m, which restricts movement from the paired source device
No support for AAC, LDAC, aptX, or any other high-quality audio codec beyond the standard SBC baseline
In/on-ear detection is absent, so playback does not pause automatically when the earbuds are removed
NFC pairing and fast pairing are not supported, requiring manual Bluetooth setup each time with a new device

Who is this for?

The Marshall Minor IV suits users who prioritize all-day wireless listening with the flexibility of wireless charging and a combined 30-hour battery window. The lightweight earbud fit and IPX4 sweat resistance make them a practical option for casual workouts or commutes, while two-device multipoint pairing appeals to anyone who regularly switches between a phone and a laptop. The built-in noise-canceling microphones and mute function also make them a workable choice for remote workers handling frequent voice calls.

Who is this NOT for?

Users who rely on active noise cancellation to block out loud or distracting environments — such as open offices, flights, or busy commutes — will find the Minor IV lacking, as neither ANC nor passive noise isolation is present. Audiophiles or those who prioritize high-resolution audio transmission will also be disappointed, given the absence of LDAC, aptX, AAC, or any other advanced codec beyond the standard baseline. Similarly, anyone who values spatial audio or immersive sound formats like Dolby Atmos will need to look elsewhere, as none of these are supported.

Final Verdict

The Marshall Minor IV is a straightforward set of true wireless earbuds that delivers where it counts for everyday listeners — a combined 30-hour battery window, wireless charging, fast charging, and reliable two-device multipoint connectivity make it a capable daily companion. Its lightweight build and sweat resistance add a degree of versatility across casual use cases, and the noise-canceling microphones hold up adequately for voice calls. That said, the absence of advanced audio codecs and any form of noise isolation means it is best understood as a practical, feature-complete option for general use rather than a specialist tool for audiophiles or commuters in demanding acoustic environments. For users whose needs align with what it offers, the wireless charging and extended battery life alone make the Marshall Minor IV a well-rounded and dependable choice in its category.
