I first used a pair of blue tooth headphones about a year ago and I was delighted with them, even though they weighed in at 260g and made me look like a Cyberman; the mere freedom of being wireless was a joy.
I am familiar with Jabra after using their first 'Jawbone' Bluetooth set for mobile and an artful design it was. That simple ergonomic style has translated across to the Halo. The unit is lightweight (96g), has smooth lines and hinged wings that switch the unit on when unfurled to form a semi circular (halo) headset.
The earpieces sit lightly on the ear and the music quality is superlative. They fold to a reasonably compact size and fit inside a supplied, padded pouch for storage.
Once unfolded for the first time, the headphones automatically start to try to pair up with Bluetooth devices. I didn't pair straight away but I found it was a simple process to complete subsequently (press a button on the headphones until a blue light comes on, activate Bluetooth on the required device and everything then happens automatically).
The headphones need to be charged for around two hours before they are first used. The manual states that they can be used whilst charging, but I found this rather impractical. The absence of an on off switch means that you need to fold them up to retain the charge.
A slight reservation is that I wonder how robust the 'snap hinge' is in daily use. A small component within the Jawbone unit I had previously broke off after about 18 months and I am hoping that Jabra have made sure that the hinge on the halo will not prove to be a point of weakness.
I didn't seem able to turn up the volume using the control on the Halo but this may have been due to the volume already being limited or because the Ipad volume control overrode it. However, volume levels were fine for normal use.
A cable is supplied to enable the Halo to be used with items that do not support a Bluetooth connection (although this would seem to defeat the object).
As with all these remote devices, it is worthwhile checking that the technology is supported by your MP3 player. For example, the remote control functions of the Halo are not supported by Apple version 3 and only to a limited extent (no forward or backtrack) in 3.1.
The halo has ousted my 'Cyberman' headset for regular use and I will be delighted with this unit as long as the hinge stands the test of time.
