They include the ability to connect to two Bluetooth devices simultaneously, volume equalization technology, along with an acoustic shock protection that protects the ear from sudden loud noises.
But probably the most interesting feature is that it is also the first mono Bluetooth headset we know of that actually supports A2DP for wireless music streaming (Most current A2DP devices are either stereo headsets or speakers).
So I thought well maybe a remnant or a program I couldn't see still running, or a lib goof.
A small dimpled circle in the middle acts as the multifunction call button, while two raised slivers on the top left and right act as the volume controls.
We found the multifunction button easy to press, even when the headset is worn.
Wrapped in matte black with streaks of silver, the BT8040's look has a tinge of high art combined with a touch of corporate sensibility.
Measuring 2.54 inches long by 0.71 inches wide by 0.47 inches deep, the BT8040 has smooth tapered sides and slightly curved edges on the top and bottom.
Though we're normally not fans of the ear tip design because of fit issues, the BT8040 comes with three different-size ear tip covers for different-size ears.
However, the headset still requires a bit of an adjustment period when we were first putting it on--it's not the sort of headset we could just put in our ear and go.
The volume controls felt a bit stiffer, but they are easy to press as well.
A small LED indicator sits on top of the volume controls.
Flip the headset over and you'll find an ear tip made up of a gel-like substance.
Jabra calls this the comfort Ear Gel tip, and it's designed to fit comfortably in the ear without the need for an ear hook or ear loop.
Unlike most other headsets, the BT8040 really shines when it comes to features.
