How to choose wireless headphones

1. The type

• True wireless earbuds: small, with a case that charges them. Easy to carry everywhere.
• Headband (over-ear or on-ear): more comfortable for long hours and usually more battery; over-ear models, which cover the whole ear, isolate well. Bulkier.
• Sports: with ear hooks or a band so they don't fall out when you run.

2. Noise cancelling

Active noise cancelling reduces constant noise, like a plane or train engine. It's useful if you travel or work somewhere noisy, and it uses a little more battery. "Ambient" or "transparency" mode lets you hear what's around you without taking them off.

3. Battery

For earbuds, look at two figures: how long they last in your ears and how much extra the case adds. Fast charging helps if you forget to charge them.

4. Calls

If you make a lot of calls, pay attention to the microphone: outdoors or in the wind, the difference between models shows.

5. Compatibility with your phone

Almost all use Bluetooth, but some features depend on your phone: app settings, automatic switching between your devices or some audio formats (codecs such as AAC, aptX or LDAC). "Multipoint" lets them stay connected to two devices at once.

6. Water and sweat

Check the IP rating: for example, IPX4 resists splashes (and, in practice, sweat); the higher the number, the more protection. For sport, make sure they at least resist sweat.

7. Comfort

Look for several sizes of ear tips and a light weight. If you can, try them first.
