Design

1.has stereo speakers
Optoma NuForce BE Free5
Devices with stereo speakers deliver sound from independent channels on both left and right sides, creating a richer sound and a better experience.
2.has a detachable cable
Optoma NuForce BE Free5
With a detachable cable you can use alternative cables, and if the cable is pulled it will pop out instead of breaking.
3.sweat-resistant
Optoma NuForce BE Free5
Resistance to sweat makes it ideal for use while doing sports.
4.weight

12.6g

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.
5.weather-sealed (splashproof)
Optoma NuForce BE Free5
The device is protected with extra seals to prevent failures caused by dust, raindrops, and water splashes.
6.can be folded
Optoma NuForce BE Free5
Foldable devices are easier to transport and take up less storage space.

Sound quality

1.highest frequency

20000Hz

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

20Hz

The lowest frequency at which the device produces audio. The lower the low-frequency response, the stronger and juicier the bass.
3.has passive noise reduction
Optoma NuForce BE Free5
The device sits tightly in place, creating an acoustic seal which reduces background noise and prevents your music from leaking out.
4.sound pressure level

95dB/mW

Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
5.has active noise-canceling (noise control)
Optoma NuForce BE Free5
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.
6.impedance

16 Ohms

Impedance is the device’s electrical resistance to the current being pushed through it. The lower the impedance, the easier it is to get higher volume and requires less power.

Power

1.Battery life

4h

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.
2.has a rechargeable battery
Optoma NuForce BE Free5
The battery can be recharged and used over again.
3.charge time

1.5h

The time it takes to fully charge the battery.
4.has a battery level indicator
Optoma NuForce BE Free5
An indicator shows you when the device has low battery.
5.battery power

55mAh

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.
6.has a removable battery
Optoma NuForce BE Free5
The battery is removable and can be replaced by the user if broken.

Connectivity

1.Can be used wirelessly
Optoma NuForce BE Free5
Wireless devices allow users more freedom of movement.
2.Bluetooth version

4.2

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.
3.has a 3.5mm male connector
Optoma NuForce BE Free5
A standard 3.5mm male connector is suitable for use with all MP3 players and computer sound cards.
4.maximum Bluetooth range

10m

The device can connect at a greater distance via Bluetooth or infrared to another device.
5.supports Wi-Fi 5 (802.11ac)
Optoma NuForce BE Free5
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.
6.supports Wi-Fi 4 (802.11n)
Optoma NuForce BE Free5
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.

Optoma NuForce BE Free5
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.
2.number of microphones

1

More microphones result in better sound quality and enable the device to filter out background noise.
3.has a noise-canceling microphone
Optoma NuForce BE Free5
These microphones are designed to filter out background noise from the desired sound. Especially useful in noisy environments.
4.control panel placed on a device
Optoma NuForce BE Free5
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.
5.Has an in-line control panel
Optoma NuForce BE Free5
There is a control panel on the cable, so you can easily operate the device without having to interact with it.
6.warranty period
