I run the headset to my iPhone 4 and my Siemens Gigaset SL400. Previously I had the very popular Jabra BT250v in use and have liked it worn / used! But since you can only connect a device that, I've decided to buy the Jabra Wave. While there are good etlich Jabra headsets of various types, but I love this Desgin Jabra Waves. The Jabra BT200 then, BT250v etc. have exactly the same style, but are not nearly as powerful and comfortable as the WAVE! The pre-series was eigtl. Also good to wear, etc., but compared to this one, you realize it gets even better!
Jabra has learned from the "weaknesses" of the pre-series and replies with this headset!
Thanks to Multiuse finally used simultaneously with 2 devices! Whether a call on the cell phone or landline is received, the Jabra Wave is immediately noticeable! Absolute buy recommendation!
