How to connect Marshall headphones to Xiaomi Redmi phone: all ways + error solving

Marshall headphones are not just a gadget, but a stylish accessory with a branded sound that you want to use with any device. But owners of Xiaomi Redmi smartphones often face problems when trying to connect them: Bluetooth does not find the device, then the sound is interrupted, then there are delays. In this article, we will analyze all possible ways of connecting, from classic Bluetooth to wired connection via an adapter, and also tell you how to fix the typical errors that prevent you from enjoying music.

Marshall’s headphones often require specific customizations on Android devices, especially when it comes to models that support aptX codec or multipoint connectivity. And Redmi smartphones (whether Note 12 Pro+, Redmi 10C or older models) sometimes get cranky because of the optimized MIUI firmware. We tested all the methods on current versions of the software and collected working solutions from basic to advanced.

1. Marshall Bluetooth Connection: Step-by-step instruction

The most common way is wireless, and even if you've never connected a headphone to a phone before, the next algorithm will help you do it in 2-3 minutes.

2. On the Xiaomi Redmi phone, open Settings → Bluetooth.
3. Turn on Bluetooth and wait for the headphone name to appear on the list (for example, Marshall Major IV).
4. Stick to the name and confirm the pairing.

If the headphones don’t show up, try:

• 🔄 Reboot the Bluetooth module on your phone (disable/enable in settings).
• 📱 Remove all previously saved Marshall devices from the list of conjugates (sometimes old connections interfere with new ones).
• 🔋 Remove and re-insert the headphones into the case (for models with a case, for example, Marshall Mode). II).

3.Wired Connection: How to Connect Marshall to Redmi without Bluetooth

Not all Marshall models support wired connectivity, but if your headphones have a 3.5mm or USB-C connector, you can use them with Xiaomi Redmi even without Bluetooth.

For headphones with 3.5 mm:

• 🎧 Connect the headphones to the phone through the adapter USB-C → 3.5mm (e.g., original from Xiaomi or third-party with chip) DAC).
• 📱 In sound settings (Settings) → Sound) select Wired Headphones as the output device.

MIUI settings:

• 🎮 Turn off Game Mode (Settings) → Special facilities → Turbo-playing mode).
• 🔋 Add an app that plays the sound (such as YouTube) to Settings → Battery → Optimizing the battery → All applications → No restrictions.

Hardware restrictions:

• 📡 If the lag only appears more than 3 meters from the phone, the problem is with Redmi's weak Bluetooth module.

7. Alternative ways of connecting: adapters and auxiliary devices

If neither Bluetooth nor wired connectivity is stable, consider alternatives:

Bluetooth transmitter:

• 📡 Buy an external Bluetooth adapter (for example, 1Mii B06 Plus or Avantek. APTX) And plug it in. USB-C-port.
• 🎧 Connect Marshall headphones to the adapter, not directly to the phone.

2. AUX-cable DAC:
