I was looking for a robust wired kit, rain-resistant and holds well at sports sessions, which can use it to listen to music from my phone but also to answer the phone with a remote control for music. Not many products met the specifications. The Jabra kit responds across with some nuances. Indeed I tested the headset with three Sony-Ericsson W810i phones (very old), Nokia E5-00 still marketed and iPhone 4. The helmet has good audio quality and fits comfortably in the ear. In addition, it comes with several adapters for the ears. A reminder of the volume on the remote control is convenient and a multi-function unit is present. However, be careful because this multi-function box does not work on all phones: - Sony Ericsson W810i and Nokia E5: the housing is used only for voice commands no opportunity to skip, pause or rewind, damage. On iPhone 4 everything is ok with one or more pressure everything works. Conclusion: good quality helmet that holds up well to the ear, delivered with extension and tips for compatibility majority of phones + storage box. Remains a high price but it fits in the period seems related benefits.
