Devices with stereo speakers deliver sound from independent channels on both left and right sides, creating a richer sound and a better experience.
Resistance to sweat makes it ideal for use while doing sports.
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.
The device is protected with extra seals to prevent failures caused by dust, raindrops, and water splashes.
5.travel bag is included
The device comes with its own special case or pouch, which is useful for safe transportation.
6.has an in-ear form
The in-ear device is ultracompact and lightweight, with little or no interference with earrings, spectacles, hats, or hairstyles. It is inserted in the ear canal itself and blocks out a lot of environmental noise. It has stronger bass tones and is unlikely to fall out of the ear.
The lowest frequency at which the device produces audio. The lower the low-frequency response, the stronger and juicier the bass.
The highest frequency at which device produces audio. The higher the high-frequency response, the clearer and crispier the treble.
3.has passive noise reduction
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
Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
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.
1.Can be used wirelessly
Wireless devices allow users more freedom of movement.
2.has a 3.5mm male connector
A standard 3.5mm male connector is suitable for use with all MP3 players and computer sound cards.
1.can be used as a headset
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
More microphones result in better sound quality and enable the device to filter out background noise.
3.Has an in-line control panel
There is a control panel on the cable, so you can easily operate the device without having to interact with it.
