"Today we are looking at the iMetal iP-HS2 Isolation Headset for iPhone that is designed to work specifically with the iPhone. The headset is very attractive and works well. The other day we reviewed teh iP-HS1 model from the same company.

I found that the ear tips are rather small in their sizes; I typically use medium ear tips on most isolation style headsets. On the iMetal iP-HS2 Isolation Headset for iPhone, I had to move up to the large to get the same seal and fit I normally see with medium tips. If you have large ears, this could be an issue for you."
