It is delivered in a somewhat awkward package and next to the headset includes two stereo plug adapter (from 3.5mm to 2.5mm and 3.5mm with other pole-occupancy), 1 porch and 3 alternative ear-pieces with different shapes , The manual and the booklet with instructions not actually need, because the operation is very simple: plug in the adapter into the phone purely and get started. The knob on the cable used to answer / hang up and a long push button to trigger an action, such as voice dialing. All connectors are 4-pin, thus you can hear + speak with appropriate devices + trigger actions. The voice quality is great - clear, clear, loud enough but not too loud, not dull, and on both sides.
The headset is comfortably light - much lighter than Bluetooth headset with its battery. It sits comfortably (typical of Jabra's design "around the ear") and will slow uncomfortable for me only after 1-2 hours, then I switch to the other ear. One of the various supplied ear parts is certainly suitable for everyone. The temple is for the ear made of very soft plastic but made from top to partially robust (much softer than my older Jabra Bluetooth headset) and the rest is hard plastic. By the clamp on the cable, the cable weight may vary depending on the collar, or similar helmet instead of pulling on the ear. The cable acts processed sensible + clean with all transitions, ie tensile strength and the headset connector and the clip easy to loosen + to clamp back inside. Meanwhile, I have involuntarily tried some breaking points and find it made sense because I was always stuck together and had to use the headset only one place very thin little liquid adhesive. The only shortcoming is the windscreen; he does not keep it from falling very easily, so I have my long since lost. Therefore, the headset on the bike, with an open car window and so hardly used is very unfortunate.
I've tried the headset successfully
* Mobile Phone Sony Ericsson Xperia Pro (Android smartphone), with the adapter to 3.5 mm jack for other pole assignment
* Nokia 2600c (simple cell phone) with the adapter to 2.5 mm jack (4-pin) as pure headphones (micro is inactive)
* Nokia E75 (older business phone) with the adapter to 3.5 mm jack for other pole assignment
* DECT phone Gigaset C610 IP to the adapter to 2.5 mm jack (4-pole)
* Laptop Lenovo T410 (has 1 jack socket which combines loudspeaker + microphone)
I would buy it immediately.
