Rating: Summary: Not bad, but mic sound quality could be better Review: This is the same headset as comes in the box with the Q105. The sound you hear through the earbud is quite good. The mic picks up your voice quite well no matter which way you head is turned, which is not bad considering it just hangs off the earbud next to your neck. The only thing I can fault it on is the mic's sounds quality: your voice will sound rather tinny to people on the other end. (The mic in the Q105 itself provides much better sound than this.) Still, people on the other end could understand me well enough and this headset is certainly light and small enough to easily carry around. So overall I'd say it's worth 3 stars.
Rating: Summary: Headset is not "Hands Free" Review: Unfortunately this is the ONLY headset that will work with this phone. Samsung support told me this was a deliberate design choice on their part and that they put a "special ring" around the headset socket to ensure other headsets would not work well (I've tried other headsets and the volume comes through so low as to be unusable). What this means is that if this set doesn't fit your ear very well (mine falls out all the time unless I duct tape it on) you will have to hold it in by hand which is very annoying when driving or your hands aren't free (e.g., in airports while pulling luggage). I would not buy another phone that did not take alternate headsets (and there are many good ones out there).
