Can you use Bluetooth headphones on a plane?
Yes. UK airlines allow Bluetooth headphones once the crew permit devices, with the phone in flight mode and Bluetooth switched back on; the UK Civil Aviation Authority says some airlines allow devices for the whole flight, including take-off and landing.
The harder question is battery. London to Sydney via Perth takes up to 21 hours 15 minutes of scheduled flying, and the Sennheiser Momentum 4 Wireless, rated at 60 hours, covers the return trip on one charge for £179.99 on Amazon UK at the time of writing (October 2026). The ranked shortlist is in Best wireless headphones UK 2026.
| Situation | Answer | Basis |
|---|---|---|
| Cruise | Yes, with the phone in flight mode and Bluetooth on | CAA cabin safety guidance |
| Taxi, take-off and landing | Depends on the airline; crew instructions apply | CAA: some UK airlines allow devices throughout |
| Safety briefing | Pause the audio and listen | CAA: pay close attention to the briefing |
| Seatback screen | Use a 3.5 mm cable or a Bluetooth transmitter | Seat sockets are wired |
| Packing | Cabin bag only, never the hold | CAA: lithium devices never in hold luggage |
Are Bluetooth headphones allowed on UK flights?
Yes. The UK Civil Aviation Authority's cabin safety guidance says some UK airlines permit smartphones, tablets and e-readers throughout the flight, including take-off and landing, and that these devices must be in flight mode unless the crew instruct otherwise. Headphones follow the device they connect to, and the CAA says passengers should always follow crew instructions on device use.
Flight mode switches off the mobile signal, not the headphones. Phones let passengers turn Bluetooth back on after enabling flight mode, and the headphones reconnect as normal. Airlines set their own rules for taxi, take-off and landing, so a passenger who flies a different carrier each trip should check the airline's website or ask the crew. The CAA also asks passengers to pay close attention to the safety briefing, which means pausing the audio while it plays.
How do you use wireless headphones with a seatback screen?
With a cable. Seatback entertainment screens use a wired headphone socket, so Bluetooth headphones connect to them through a 3.5 mm audio cable, or through a small Bluetooth transmitter that plugs into the socket and pairs with the headphones.
The Sennheiser Momentum 4 Wireless ships with a 3.5 mm audio cable and an airplane adapter, according to its Amazon UK listing. Sony lists a 3.5 mm stereo mini jack input on the Sony WH-1000XM6, and RTINGS notes that its noise cancelling keeps working while the cable is plugged in. RTINGS also notes that the Soundcore Space Q45 can be used wired. Earbuds have no socket, so earbud owners who want the seatback film need a transmitter.
Will your headphones last a long-haul flight?
Every flagship over-ear in this guide lasts London to Sydney one way on a single charge, but only the 60-hour and 50-hour pairs cover the return. Compare Electronic's table divides each maker's rated battery with noise cancelling on by the longest scheduled flying time from London Heathrow on each route.
- Paris (Charles de Gaulle): up to 1 h 25 min
- New York (JFK): up to 8 h 35 min
- Tokyo (Haneda): up to 14 h 15 min
- Sydney via Perth: up to 21 h 15 min of flying (16 h 50 min plus 4 h 25 min)
| Headphones | Rated ANC battery | Paris | New York | Tokyo | Sydney | Sydney return (42 h 30 min) on one charge |
|---|---|---|---|---|---|---|
| Sennheiser Momentum 4 Wireless | 60 h | 42 | 6 | 4 | 2 | Yes, 17 h 30 min spare |
| Soundcore Space Q45 | 50 h | 35 | 5 | 3 | 2 | Yes, 7 h 30 min spare |
| Sony WH-1000XM6 | 30 h | 21 | 3 | 2 | 1 | No, recharge in Sydney |
| Sony WH-1000XM5 | 30 h | 21 | 3 | 2 | 1 | No, recharge in Sydney |
| Apple AirPods Pro 3 (earbuds) | 8 h per charge | 5 | 0 | 0 | 0 | No, case top-ups needed |
Measured figures tell the same story. RTINGS measured 62 hours from the Momentum 4 Wireless, 31.75 hours from the Sony WH-1000XM6 and 27 hours from the Sony WH-1000XM5, which still leaves 5 hours 45 minutes after the Sydney legs. Connection time on the ground adds to the total, so passengers on a two-leg trip should charge in the transit lounge where they can. Lithium-powered devices belong in the cabin bag: the CAA says they should never go in hold luggage, and it recommends carrying devices with batteries under 100 Wh in the cabin. The power bank rules are in Can you take a power bank on a plane?, and the over-ear against earbud choice in Should I get headphones or earbuds?.
Which headphones are best for flying?
The Sennheiser Momentum 4 Wireless is the best headphone for flying on battery and kit, at £179.99 on Amazon UK at the time of writing (October 2026). Sennheiser rates it at 60 hours per charge, and the box includes a 3.5 mm cable and an airplane adapter for seatback screens.

Frequently asked questions
Can you use Bluetooth headphones during take-off and landing?
It depends on the airline. The UK Civil Aviation Authority says some UK airlines permit smartphones, tablets and e-readers throughout the flight, including take-off and landing, in flight mode unless the crew instruct otherwise. Other airlines ask passengers to stop using devices for those phases. Crew instructions always apply, so passengers should check the airline's rules and listen to the briefing.
Do you need flight mode to use Bluetooth headphones on a plane?
Yes. The UK Civil Aviation Authority says devices must be in flight mode unless the crew instruct otherwise. Flight mode switches off the phone's mobile signal, and phones let passengers turn Bluetooth back on afterwards, so wireless headphones such as the Sony WH-1000XM6 keep working. Passengers should follow the airline's own rules and the crew's instructions.
Can you connect wireless headphones to in-flight entertainment?
Usually by cable. Seatback screens normally have a 3.5 mm headphone socket, so headphones with a wired input work directly. The Sennheiser Momentum 4 Wireless ships with a 3.5 mm audio cable and an airplane adapter, according to its Amazon UK listing. A small Bluetooth transmitter that plugs into the socket lets earbuds without a cable connect to the screen.
Will headphone battery last a flight to Australia?
Yes, on one charge, for most flagships. London to Sydney via Perth takes up to 21 hours 15 minutes of scheduled flying. Sony rates the WH-1000XM6 at 30 hours with noise cancelling, and Sennheiser rates the Momentum 4 Wireless at 60 hours, enough for the return journey as well. Earbuds rated at 8 hours per charge need several top-ups from the case.
Can you put wireless headphones in checked luggage?
Pack them in the cabin bag. The UK Civil Aviation Authority says devices powered by lithium batteries should never be packed in hold luggage, because the batteries can overheat and cause a fire. If a cabin bag is taken for the hold at the gate, the CAA advises removing lithium-powered devices first. The same rules cover power banks and phones.
Are noise cancelling headphones worth it for flying?
Yes. Noise cancelling works best on steady low-frequency noise such as engine drone. RTINGS says the Sony WH-1000XM6 easily reduces noise from airplane engines, and that the Soundcore Space Q45 can easily cut down the hum of a bus or plane engine. The Soundcore Space Q45 costs £109.99 on Amazon UK at the time of writing (October 2026).
