Hi, I am a classical musician. I would like to buy a not to big and clumsy headset (it tends to look ridiculas on me) with real sound, in short-I want it to sound like i am sitting in the concert hall. I want to hear every instrument clearly yet not with a thin sound. I prefer the headset to be half sound proof, meaning that i still can hear if someone is calling me, but that's not necessary. the budget is around 50 bucks but it's flexible if you have something very recommeded. Since i am from Israel, It has to be available on ebay with free/low cost shipping to Israel. Thank you very much!
