Output power

The total power of all channels of the speaker system. The higher the power, the larger the size of the room in which the audio system can be used, however, more powerful portable speakers usually have larger dimensions and weight.

Frequency range

The range of audio frequencies reproduced by the audio system. The wider the range, the richer the sound, the more details the speakers can convey, especially in the low and high frequencies. At the same time, we note that the average human ear is able to hear sounds in the range of about 16 – 20,000 Hz, and it makes no sense to provide a wider range in speakers — a person simply will not hear it. Also note that a wide frequency range alone does not guarantee good sound quality.

More features

LCD display. This screen makes device control more visual: it can display the operating mode, equalizer settings, battery charge level, etc.

— Handle/strap. The presence of a handle or strap makes wearing the speaker more comfortable. So the handle is used mainly in large stereo speakers and makes them similar to boomboxes ( cassette recorders) of yesteryear. The strap can be used both for large speakers and for miniature ones, which allows you to hang them on your hand, on elements of a backpack, etc.

- Flashlight. This feature likely won't replace a high-end, dedicated flashlight. The power of the built-in flashlight is usually enough to illuminate at least a distance of 2 - 3 meters, and models with a bicycle mount (see above) can even play the role of a headlight (although, again, they are inferior to specialized bicycle lights).

Carabiner/suspension A device in the form of a latch that allows you to attach the speaker to items of clothing, backpack straps, etc.

Bicycle mount. A special device designed to mount the speaker on a bicycle, usually on the handlebars, at the user’s fingertips. Such models are often complemented by a hands-free function, which allows you to communicate on the phone without taking your hands off the...steering wheel.

Battery capacity

Theoretically, a higher capacity allows to achieve greater battery life, but in fact, the operating time also depends on the power consumption of acoustics — and it can be very different, depending on the characteristics and design features. So this parameter is secondary, and when choosing it is worth paying attention not so much to the battery capacity, but to the directly claimed operating time (see below).

Battery life

Operating time of a portable audio system without connecting to an external power source (network or USB port, depending on the capabilities). Note that manufacturers tend to indicate battery life in their specifications under optimal conditions for energy saving: at low volume, without using additional functions, etc. Therefore, in fact, this indicator may be noticeably lower than the claimed one, and speakers with a long operating time will not sound at full volume for the specified hours.
