Marshall Headphones Wireless Charging Support Explained
Yes, some Marshall headphones support wireless charging, but not all of them. Specifically, the Marshall Monitor II A.N.C. and the Marshall Major IV are the two models that include built-in wireless charging capability, allowing you to recharge them by placing them on any Qi-compatible charging pad. Other Marshall headphone models, such as the Major III and Monitor, do not have this feature and require a wired connection via their included USB or micro-USB cable.
Which Marshall Headphones Have Wireless Charging
Marshall has released a handful of over-ear and on-ear headphones, and wireless charging is a relatively recent addition to their lineup. Here is a clear breakdown of the models that support it:
- Marshall Major IV – On-ear headphones with wireless charging built into the right ear cup. They work with any standard Qi charging pad.
- Marshall Monitor II A.N.C. – Over-ear active noise cancelling headphones that also support Qi wireless charging, with the charging coil located in the right ear cup.
Older models like the Major III, Major II, and the original Monitor do not have wireless charging. If you own one of those, you will need to use the included charging cable. The Major IV and Monitor II A.N.C. also include a USB-C charging cable for times when a wireless pad is not available, so you are never locked into one method.
How Wireless Charging Works on These Headphones
Wireless charging uses a technology called electromagnetic induction. A Qi charging pad contains a copper coil that generates an alternating magnetic field. The headphone has a matching receiver coil, usually placed in the ear cup, that converts that magnetic field back into electrical current to charge the battery.
On the Major IV and Monitor II A.N.C., the receiver coil is located in the right ear cup. To charge, you simply lay the headphones on their side with the right ear cup facing down on the center of the charging pad. The headphones do not need to be perfectly aligned, but they do need to be reasonably centered for the charging to start. Most Qi pads have a small indicator light that turns on when a device is being charged, which helps confirm proper placement.
Because the coil is in the ear cup, you cannot charge the headphones while wearing them. You also cannot use a charging pad that is too small, like a watch charger, because the coil in the headphone is larger than the pad’s charging area.
Charging Speed and Battery Life
Wireless charging on these Marshall headphones is slower than wired charging. The Major IV supports up to 5W wireless charging, which is the standard for most Qi pads. A full charge from empty takes roughly 3 to 4 hours wirelessly, compared to about 2 hours with a USB-C cable. The Monitor II A.N.C. behaves similarly.
Battery life remains the same regardless of how you charge. The Major IV offers up to 80 hours of playback on a full charge, which is exceptional for an on-ear headphone. The Monitor II A.N.C. provides about 30 hours with active noise cancelling turned on, and up to 45 hours with ANC off. These figures are from Marshall’s official specifications and are based on moderate volume levels.
A useful feature on both models is quick charging. A 15-minute wired charge gives you about 15 hours of playback on the Major IV, and about 5 hours on the Monitor II A.N.C. Wireless charging does not offer the same fast top-up, so if you are in a hurry, plugging in the cable is the better option.
What Qi Charging Pad Should You Use
Any Qi-certified charging pad will work with these Marshall headphones. Qi is the universal standard used by most smartphones, earbuds, and smartwatches, so you likely already own a compatible pad. There are a few things to consider when choosing one:
- Size: A pad designed for phones (about 70–80 mm in diameter) works well. Smaller watch-style pucks may not cover the headphone’s coil properly.
- Output: A 5W or 10W pad is fine. The headphones will only draw 5W, so a higher-wattage pad does not charge them faster.
- Stand vs. flat pad: Flat pads are best because you need to lay the headphone flat on its side. Vertical stands are not suitable.
- Metal objects: Keep keys, coins, or other metal items off the pad while charging, as they can overheat.
If you do not have a Qi pad, you can buy one from any electronics retailer. They are widely available and relatively inexpensive. Just make sure it says “Qi-certified” on the packaging to ensure compatibility and safety.
Common Problems and How to Fix Them
Wireless charging can occasionally be finicky. Here are the most common issues and what to do:
- Headphones not charging: First, check that the right ear cup is centered on the pad. Move the headphones slightly until the pad’s indicator light turns on. Also make sure the pad is plugged into a power source.
- Charging stops after a few minutes: This is often caused by overheating. Remove any case or cover on the headphones, and move the pad to a cooler surface. Also ensure the ear cushion is not too thick or worn, which can increase the distance between the coils.
- Slow charging: Wireless charging is inherently slower than wired. If it seems excessively slow, try a different Qi pad or remove any phone case from the headphones (though they do not come with cases).
- Pad works with phone but not headphones: Some pads have a feature that only activates when they detect a device with a certain size or shape. Try placing the headphone more precisely on the center of the pad, or use a different pad.
If none of these steps work, check that the headphone’s firmware is up to date through the Marshall Bluetooth app. Occasionally, a firmware update improves charging behavior.
Comparing Wired vs. Wireless Charging
When you have a choice, it helps to know the trade-offs. Wired charging via USB-C is faster, more reliable, and allows you to use the headphones while they charge (though you cannot wear them while plugged in easily). Wireless charging offers convenience—no cable to plug in, just drop the headphones on a pad—but it is slower and requires precise placement.
For daily top-ups, wireless is ideal. You can keep a pad on your desk or nightstand and simply set the headphones down when you take them off. For a full charge from empty, wired is better if you are in a hurry. Most users end up using both: wireless for routine charging, wired for quick boosts before heading out.
One important note: wireless charging generates more heat than wired charging. Heat degrades lithium-ion batteries over time. To maximize battery lifespan, avoid leaving the headphones on a charging pad all day every day. Once they reach 100%, unplug or remove them from the pad.
Frequently Asked Questions
Can I use my phone’s wireless charger for my Marshall headphones?
Yes, as long as the charger is Qi-certified and is a flat pad. Most phone chargers meet this requirement. Just place the right ear cup on the center of the pad. If your phone charger is a magnetic one (like MagSafe), it will still work, but the magnets may not align perfectly with the headphone’s coil, so you may need to adjust the position.
Do Marshall Major IV come with a wireless charging pad?
No, Marshall does not include a charging pad in the box. You only get a USB-C cable. You need to provide your own Qi wireless charger, which is sold separately.
Can I charge my Marshall headphones wirelessly with a power bank?
Only if the power bank has a built-in wireless charging pad. Many modern power banks include a Qi pad on top, so you can place the headphones on the power bank to charge. If your power bank only has USB ports, you will need to use the cable.
Is wireless charging bad for the battery?
Wireless charging is not inherently bad, but it does generate more heat than wired charging. High temperatures are the main enemy of lithium-ion batteries. To keep your battery healthy, avoid charging in direct sunlight or on hot surfaces, and do not leave the headphones on the pad for days. Occasional wireless charging is perfectly fine.
Why is my Marshall headphone not charging wirelessly even though it’s on the pad?
First, confirm the right ear cup is facing down and centered on the pad. Check that the pad is plugged in and that its indicator light is on. If the pad has a foreign object detection feature, it may be triggered by the metal in the headphone hinge. Try placing the headphone slightly off-center, or use a different pad. Also, make sure the headphone battery is not completely dead—some devices need a small initial charge via cable before they can accept wireless charging.
