JLab Go Air review: specs and price

Resistance to sweat makes it ideal for use while doing sports.

The Ingress Protection (IP) rating classifies the degree of protection against dust and water. Higher ratings are better. For example, a device rated IP68 can resist immersion into water for a certain time, specified by the manufacturer.

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

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.

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

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.

This type of device allows you to listen at lower volume levels, causing less ear fatigue as you don't have to crank up the volume to overcome background noise. Ideal for plane rides and morning commutes.

The device sits tightly in place, creating an acoustic seal which reduces background noise and prevents your music from leaking out.

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

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

The driver unit is the component that produces sound in the device. Bigger drivers are more powerful and can produce better bass.

Devices with a higher sound pressure level are generally louder when supplied with any given audio source.

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

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

It's the 'loudness' of the sound that the microphone can pick up.

The time it takes to fully charge the battery.

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 battery can be recharged and used over again.

The battery life of the charging case as given by the manufacturer. A charging case with a longer battery life allows you to recharge your headphones on the go multiple times before having to recharge the case itself.

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.

An indicator shows you when the device has low battery.

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.

Wireless devices allow users more freedom of movement.

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.

Bluetooth aptX is an audio codec used for transmitting hi-resolution audio wirelessly from Bluetooth-enabled devices. Developed by Qualcomm, the aptX audio technology includes variations such as aptX HD, aptX Low Latency, and aptX Adaptive.

The device can connect at a greater distance via Bluetooth or infrared to another device.

The USB Type-C features reversible plug orientation and cable direction.

A headset is one headphone or pair with a built-in microphone. Headsets can be used for apps that require communication i.e. Skype, games with voice chat, mobile phones, etc.

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

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

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.

The device comes with its own special case or pouch, which is useful for safe transportation.

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

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.

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.

The device is designed in a way that allows sound to go out through the back of the ear cups, which usually have vents or perforations. This design provides very natural and accurate sound.

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

A wind noise reduction microphone is designed to reduce wind interference, providing sharper audio in windy situations.

The audio signal is coded and encrypted digitally, allowing for highly secure conversations.
