Buying a wireless Bluetooth speaker: how to choose the right model for you

A wireless Bluetooth speaker may seem easy to choose: connect your phone, press play and you’re ready to go. However, models vary considerably in size, sound quality, battery life, and protection against water and dust. A small speaker can be useful on a bike, while a heavier model may be better suited to a party or a permanent spot at home.

Pay particular attention to these common pitfalls:

  • A high wattage does not tell you everything about sound quality. The stated power may be peak power rather than RMS power. The drivers, cabinet and tuning also affect the sound.
  • “Water-resistant” does not mean unlimited protection. An IP rating indicates the conditions against which a product has been tested. Salt water, chlorine, high pressure and prolonged immersion may fall outside the specification.
  • The stated battery life is a maximum. Volume, lighting, bass reproduction and the functions you use will reduce playback time. A speaker with long battery life should therefore not be judged solely by the highest number of hours.
  • Bluetooth is not the same as Wi-Fi. A Bluetooth speaker works directly with a smartphone or tablet. A Wi-Fi speaker can offer extra features, such as multi-room or streaming over a home network, but is less flexible without a network connection.

Which specifications are important?

1. Power, drivers and listening space

For a bedroom, kitchen or desk, a compact portable speaker is often sufficient. As well as the power, look at the number of drivers and the design. A tweeter mainly handles high frequencies, while a woofer or passive bass radiator can contribute to lower frequencies.

A model with multiple drivers and a higher RMS output is more suitable for a living room, garden or gathering. However, pay attention to the dimensions and weight: a powerful Bluetooth speaker is not automatically practical to carry around.

For films, a soundbar with subwoofer is generally more suitable than a standalone portable Bluetooth speaker. A soundbar is designed for use with a TV and may offer connections such as HDMI eARC or optical audio. Check beforehand that your television supports the relevant connection.

2. Battery life and charging options

Battery life is usually stated at a particular volume and sometimes with the lighting switched off. For a day at the beach, camping or cycling, a stated playback time of 12 to 20 hours is practical, but remember that conditions will affect it.

Also check:

  • whether charging uses USB-C;
  • how long a full charge takes;
  • whether the speaker can play while charging;
  • whether the battery status is visible;
  • whether lighting and extra bass affect playback time.

A compact model with six hours of battery life may be perfectly suitable for short trips. For a party or a long day outdoors, a larger speaker with a higher capacity is the more logical choice.

3. IP rating and outdoor use

For a Bluetooth speaker for outdoor use, the IP rating is important. The first digit indicates protection against solid particles, such as dust. The second digit relates to water.

  • IP67 generally means complete protection against dust and protection against temporary immersion under specified conditions.
  • IP66 indicates protection against dust and powerful water jets, but not automatically against immersion.
  • IPX6 indicates protection against water, but says nothing about dust protection because the first digit has not been specified.

According to the safety information for the Sony SRS-XB100, the IP67 rating applies to immersion in fresh water up to one metre deep for a maximum of 30 minutes. The manufacturer advises against exposure to salt water, chlorine and high-pressure jets. Use a waterproof Bluetooth speaker within the limits of its stated rating, and allow the connections to dry thoroughly before charging.

Bluetooth features that make a practical difference

Bluetooth 5.3 or 5.4 can provide up-to-date connectivity, but range and stability also depend on obstacles, your phone and the surroundings. Dual-device or multipoint pairing is useful when two people want to play music without repeatedly reconnecting.

With stereo pairing, you can connect two compatible speakers. Always check that both units support the same pairing protocol. TWS or stereo pairing also does not mean that every speaker will automatically work with every brand.

A built-in microphone is useful for phone calls. For controlling the speaker while out and about, physical buttons are easier than relying solely on an app. An app, on the other hand, may offer additional equaliser settings, lighting modes or multi-room functions.

Frequently asked questions about wireless Bluetooth speakers

How do I connect a Bluetooth speaker to my phone?

Switch on the speaker and activate pairing mode. Then open the Bluetooth settings on your smartphone, select the speaker’s name and confirm the connection. If the model does not appear in the list, briefly switch Bluetooth off and back on again, or remove an old pairing. For specific button combinations, consult the supplied manual.

How long does a portable speaker’s battery last?

That depends on the volume, lighting, temperature and functions in use. The stated battery life is usually a maximum measured under specific conditions. For everyday use, it is sensible to allow some leeway. If you need 10 hours of music, for example, choose a model whose manufacturer states more than 10 hours.

Does a Bluetooth speaker use a lot of power?

During use, a speaker draws power from its internal battery. Energy consumption mainly depends on the volume, amplifier power and lighting. Charging via USB-C is convenient, but use a suitable adapter in accordance with the manufacturer’s instructions. A Wi-Fi speaker may also remain connected to the network in standby, whereas a Bluetooth speaker is generally only active when connected to a device.
