The e40bt review is a wireless headset that has Bluetooth technology that allows you to play music and take calls without the need for a wire. It also has a built-in rechargeable lithium-ion battery that offers up to 16 hours of listening time. You can use the included aux cable to listen to your music if the battery dies.
The headphones have 40 mm drivers that deliver JBL’s PureBass performance, which gives the music you listen to rich bass tones. The on-ear headphones rest comfortably around your ears, with ear cushions that cradle your head while keeping noise out. The lightweight, ergonomically designed headband is adjustable and features a soft polymer of high tensile strength. The 3D aluminum swivel hinges allow the ear cups to perfectly align with your ears.
You can control your audio with the buttons on the left ear cup. There are volume up and down, as well as a multi-function button that lets you skip tracks or take hands-free calls. The headphones have a built-in microphone and feature echo-cancelation, so your voice sounds clear to people on the other end of your call.
The e40bt is an excellent option for Bluetooth headphones under $100. It is not heavy on the bass, but it has a great balance of highs and lows. It is comfortable to wear for long periods of time and the battery life is good. It is available in a variety of colors to suit your style.
