Choosing wireless earbuds: specifications and pitfalls to look out for

Wireless earbuds are handy for listening to music, making phone calls, travelling, working and exercising. But a long list of features doesn’t automatically mean a model is right for you. A low price might look appealing, for example, but a short battery life, poor fit or unclear water-resistance rating could lead to disappointment later.

In this buying guide from the Joybuy Product Recommendation Officer, we compare the key specifications of Bluetooth earbuds. You’ll find out what to look for in noise-cancelling earbuds, sports earbuds, earbuds with a microphone and open-ear models.

Three common pitfalls when buying wireless earbuds

1. Misinterpreting a high IP rating

An IPX4 or IPX5 rating doesn’t mean you can submerge the earbuds. IPX4 generally indicates protection against splashes, while IPX5 indicates protection against water jets. The charging case often has a different rating, or may not be water-resistant at all.

Always check:

  • Whether the rating applies only to the earbuds.
  • Whether the charging case is protected against moisture.
  • Whether the manufacturer advises against swimming or submersion.
  • Whether the USB-C port needs to be dry before you charge the earbuds.

An IPX5-rated model may be suitable for rain and sweat, but not for swimming.

2. Comparing battery claims without checking how they were measured

A claimed long battery life often refers to the total with the charging case, and sometimes applies only with active noise cancellation switched off. Battery life may be shorter with ANC on, at high volumes or when making lots of phone calls.

Look out for the difference between:

  • Playback time per charge: how long the earbuds themselves last.
  • Total playback time: the earbuds plus the charging case.
  • Fast charging: how much playback time you get after, for example, ten minutes of charging.
  • Talk time: usually shorter than music playback time.

A model offering 7 hours per charge may be enough for your commute. For long journeys, a case with a total capacity of 36 to 55 hours may be more practical.

3. Mistaking feature names for guaranteed performance

Terms such as “AI noise reduction”, “3D audio” and “real-time translation” sound impressive, but how well they work depends on the software, phone, app and surroundings. Some brands’ product information states that AI translation may work only through a compatible app and internet connection. So check which features are actually supported by your smartphone.

Which specifications matter?

Bluetooth version and connection

Bluetooth 5.3, 5.4 and 6.0 can offer a stable connection and lower power consumption, but your experience also depends on your phone and the codecs it uses. SBC and AAC are common codecs for everyday listening. If you mainly watch videos or play games, look for a stated low-latency mode.

Multipoint or dual-device connectivity is handy if you regularly switch between a laptop and smartphone. Just check whether both devices can stay connected at the same time.

Sound, drivers and fit

A larger driver, such as 10 mm or 14.2 mm, doesn’t tell you everything about sound quality. Tuning, fit and the seal in your ear have at least as much influence.

Choose according to how you’ll use them:

  • In-ear earbuds: block out more ambient noise and often offer a secure fit.
  • Semi-in-ear models: feel less closed off, but may fit less securely in some ears.
  • Open-ear earbuds: let you hear more of your surroundings and are practical for walking or cycling. They usually offer less isolation on busy trains.
  • Ear-clip or ear-hook models: can stay secure during exercise without sitting deep in your ear.

Noise cancelling and microphones

Active noise cancellation, or ANC, uses microphones and electronics to reduce ambient noise. The results vary from person to person and between environments. Low, constant sounds such as train or aircraft engines are often easier to reduce than voices.

For calls, the number of microphones and the noise-cancellation technology used are relevant. A product page might, for example, list six microphones and AI noise reduction. These are product specifications, not a guarantee that every caller will hear your voice perfectly in every situation.

Frequently asked questions about wireless earbuds

How do I connect Bluetooth earbuds to my phone?

Open your smartphone’s Bluetooth settings, charge the earbuds and take them out of the case. Select the product name from the list of available devices. If they won’t pair, remove any previous connection, put the earbuds back in the case and try again. For models with translation, also check the accompanying app and its permissions.

How long do wireless earbuds last?

Battery capacity gradually decreases with charging cycles and operating temperature. Don’t leave the case for long periods in extreme heat or cold, and use certified charging accessories. A model with fast charging can be handy if you often forget to charge your earbuds. You usually only need to replace them when the playback time or connection no longer meets your needs.

Are noise-cancelling earbuds suitable for cycling?

Take care. ANC can reduce ambient noise and warning signals. When cycling or in traffic, it’s best to use transparency mode or open-ear earbuds, and keep the volume low. No model is a substitute for paying attention to traffic.
