Wanted to thank the OP for his review. I tried a pair of ER4P recently and they were good, but just not right for me. So I sold them and was checking around and when I saw that an experienced member touted these phones, I got interested. Amazon was selling them for $159 plus I had a coupon for $25, so why not try them? Well, they are great in my view. For $134, a true bargain. As someone else noted, while the latest low budget phones, the MH1C, sound very good for the money, the BA-200s are much better to me. Having both is nice too. Now, I am going to check into a BT option so I can use these with my smartphone. I am thinking the Samsung HS3000.
I can only use them over the ear, though. Don't see the point in wearing them down.
