Marshall Minor III True Wireless Earbuds – Black

Marshall Minor III True Wireless Earbuds (Black)

The Marshall Minor III in Black brings the brand’s stage-amp identity to true wireless earbuds: an open-fit design with custom-tuned 12 mm drivers, the Marshall script logo on a textured charging case, and a control scheme kept deliberately simple. There is no noise cancelling and no silicone tip sealing your ear canal. Instead, Minor III aims at listeners who want Marshall’s loud, crisp signature sound, an earbud that sits comfortably for hours, and the freedom to hear what is happening around them.

Key features

• 12 mm custom-tuned dynamic drivers with Marshall signature sound
• 25 hours of total wireless playtime: 5 hours in the earbuds, 20 more in the case
• Bluetooth 5.2 with aptX, AAC and SBC codec support
• Mirrored touch controls on both earbuds, with auto-pause and auto-play
• IPX4 water resistance on the earbuds
• Wireless charging case, also chargeable over USB-C
• Quick charge: 15 minutes gives 1.5 hours of playtime
• Marshall Bluetooth app with equaliser presets and firmware updates

Custom-tuned 12 mm drivers

Each earbud carries a 12 mm dynamic driver, large by true wireless standards, tuned to Marshall’s specification. The published figures are a frequency response of 20 Hz to 20 kHz, driver sensitivity of 93 dB SPL (179 mV at 1 kHz) and 32 ohm impedance. In listening terms that translates to the house Marshall character: strong, punchy lows, clear mids for guitars and vocals, and crisp top end, at volumes that leave headroom to spare. Support for the aptX codec alongside AAC and SBC keeps wireless quality high on compatible Android and Apple devices.

Open fit and mirrored touch controls

Minor III uses an open, tip-free fit: the earbud rests in the ear without a silicone seal pushing into the canal. Many listeners find this more comfortable over long sessions and it keeps outside sound audible, which suits commuting and office wear. The trade-off is less passive isolation than sealed designs, which is a deliberate part of this model’s brief. Controls are touch-sensitive and mirrored on both buds, so either earbud can play and pause, skip tracks, adjust volume or handle calls. Removing an earbud pauses playback automatically and putting it back resumes, and each bud carries its own microphone for calls and voice assistant access.

25 hours of playtime and wireless charging

The earbuds hold 5 hours of playtime per charge, and the charging case carries four additional full charges for 25 hours in total. A 15 minute quick charge returns about 1.5 hours of listening. Recharging takes about 1.5 hours for the earbuds and 2 hours for the case over USB-C, and the case also charges wirelessly on any Qi charging pad. An eco charging option in the app can limit charging behaviour to help extend battery lifespan. At 4.0 grams per earbud and 40 grams for the case, the whole package disappears into a pocket.

Connection and everyday use

Bluetooth 5.2 provides the wireless link with a 10 metre range, and pairing is a simple open-the-case-and-connect routine. The IPX4 rating on the earbuds covers sweat and rain splashes for workouts and wet-weather commutes, though the case itself is not water resistant. The Marshall Bluetooth app adds equaliser presets so you can shape the sound, customisation options and over-the-air updates that keep the earbuds current. There is no active noise cancellation, multipoint is not part of the specification, and that honesty is the point: Minor III concentrates its budget on drivers, battery and build.

For Marshall fans who want the signature sound in their pocket, the Minor III in Black delivers it plainly: big custom-tuned drivers, 25 hours of total playtime, wireless charging and an open fit that stays comfortable all day.
