Oontz Angle 3 Ultra (4th Gen) 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.

A speaker driver is an individual transducer that converts electrical energy to sound waves. More drivers may result in better sound quality.

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.

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

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.

Audio output power is based on the number of speakers and their power in watts. High audio output power results in loud, clear sounds.

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.

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.

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.

You can use the device with standard batteries instead of a power supply.

The battery is removable and can be replaced by the user if broken.

An auxiliary input allows you to play other audio sources by connecting them through a simple audio connection like a 3.5mm jack, i.e for MP3 or portable DVD/CD player.

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.

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

With more USB ports, you are able to connect more devices.

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.

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

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.
