How to choose wireless earbuds

Battery life: check both numbers

Listings usually give the battery life of the earbuds on their own, then add the extra charges stored in the case. Look for both figures. Real-world battery life depends on volume and on features such as noise cancelling, so expect it to land a little below the headline number.

Fit and comfort

Earbuds that don't sit securely sound thin and fall out. In-ear designs with swappable tips let you find a proper seal. Open-fit designs rest in the ear, feel lighter and let in more outside sound. If comfort matters to you, read the returns information before you buy.

Bluetooth and sound

Bluetooth is how the earbuds connect to your phone. Newer versions generally improve connection stability and power use, but a higher version number does not guarantee better sound. Audio codecs are the formats used to send sound: SBC works with everything, AAC is common on iPhones, and options such as aptX need support on both your phone and your earbuds. For everyday listening, SBC or AAC is perfectly fine.

Calls and noise

If you take calls, check that the listing mentions microphones. Active noise cancelling uses microphones and electronics to reduce background noise, while passive isolation relies on how well the earbuds fit. Both are useful. Active noise cancelling usually costs more and uses extra battery.

Water and sweat resistance

A rating such as IPX4 means the earbuds are protected against splashes, which suits workouts and light rain. Higher ratings, such as IPX7, mean they can handle brief immersion in water. Ratings usually apply to the earbuds and not always to the charging case, and they are not a reason to swim or shower with them unless the manufacturer says so. If a listing doesn't state a rating, don't assume there is one.

Charging and the case

USB-C is the most common charging connector today and is easy to share with your other devices. Some cases also charge wirelessly. Claims that state how much playback you get from a short charge can be handy if you are often in a hurry.

Before you buy: a quick checklist

• Compare battery life for the earbuds alone and with the case.
• Check what is included, such as a cable, spare ear tips and a manual.
• Confirm the earbuds work with your phone or other devices.
• Look for a water-resistance rating if you will use them for exercise.
• Find the delivery details, returns information and a way to contact the seller.
• Be cautious of very high claims with no detail behind them.
