JBL GO 2 review: specs and price

Volume is the quantity of three-dimensional space enclosed by the product's chassis or, in simpler terms, the space the product occupies.

There is a control panel on the device body, so you can easily access the volume control or remote without having to interact with a cable or another device it's connected to.

The device is protected with extra seals to prevent failures caused by dust, raindrops, and water splashes.

The device is dustproof and water-resistant. Water-resistant devices can resist the penetration of water, such as powerful water jets, but not being submerged into water.

Devices with neodymium magnets are lighter and more powerful than those which use ferrite magnets. They also have more bass and clear high notes.

When covered under the manufacturer’s warranty it is possible to get a replacement in the case of a malfunction.

We consider a lower weight better because lighter devices are more comfortable to carry. A lower weight is also an advantage for home appliances, as it makes transportation easier, and for many other types of products.

With a detachable cable you can use alternative cables, and if the cable is pulled it will pop out instead of breaking.

A remote control allows you to control the device remotely. The remote control can be included or optional.

Devices with stereo speakers deliver sound from independent channels on both left and right sides, creating a richer sound and a better experience.

The lowest frequency at which the device produces audio. The lower the low-frequency response, the stronger and juicier the bass.

Devices with a subwoofer have a higher quality, deeper bass.

A passive radiator is a type of driver (speaker) that doesn't have a voice coil and a magnet. The sound vibrations produced by a passive radiator depend on its mass and the size of its enclosure. It is usually used in combination with a woofer to produce deep bass tones.

The highest frequency at which device produces audio. The higher the high-frequency response, the clearer and crispier the treble.

These microphones are designed to filter out background noise from the desired sound. Especially useful in noisy environments.

Signal-to-noise ratio is a measure that compares the level of a desired signal (meaningful information) to the level of background noise (unwanted signal), the bigger the less perceived noise.

More microphones result in better sound quality and enable the device to filter out background noise.

A magnetic shielding limits the coupling of a magnetic field between two devices. The purpose is to prevent magnetic fields from interfering with electrical devices and avoid distortion (of TV, monitors, hard drives etc.).

The battery can be recharged and used over again.

An indicator shows you when the device has low battery.

Battery power, or battery capacity, represents the amount of electrical energy that a battery can store. More battery power can be an indication of longer battery life.

The device's battery life (when in use) as given by the manufacturer. With a longer battery life you have to charge the device less often.

The time it takes to fully charge the battery.

The manufacturer offers a branded wireless charging kit. To charge the device, you simply put it down on its charging base.

Bluetooth is a wireless technology standard that allows data transfers between devices placed in close proximity, using short-wavelength, ultra-high frequency radio waves. Newer versions provide faster data transfers.

The device can connect to Wi-Fi.

With a standard mini jack socket, you can use the device with most headphones.

Device supports fast Bluetooth pairing using NFC so it can communicate with other devices over Bluetooth. You can fastly pair devices without entering a code by simply holding one device next to the device with which it is to be paired.

Wi-Fi 4 (802.11n) is a wireless standard released in 2009. It has faster transfer rates and improved security compared to its predecessors – a, b, and g.

802.11ac wireless works on the 5GHz frequency range. It offers higher transfer rates, improved reliability, and improved power consumption. It provides advantages for gaming and HD video streaming.

A standard 3.5mm male connector is suitable for use with all MP3 players and computer sound cards.

AirPlay allows wireless connection of Apple devices with external screens or speakers. You may stream computer screen, video and music from iOS devices, play games like on consoles or present your slideshows easily on your TV.

Wireless devices allow users more freedom of movement.

This technology allows the users to use their smartphone as a remote control for the device.

A built-in FM radio tuner allows you to listen to most of the live-broadcasted FM radio stations without using the internet.

The device has an option to mute/unmute a conversation directly from the device.

You can use your voice to control key functions of the device and you can easily access your device without pushing any button.

A sleep timer is a function that shuts off the power after a preset amount of time.

With voice prompts, you will automatically receive information via audio messages – for instance, you may find out that the battery is running low, and it's time to recharge the device.
