I have several iGrados, needed two of them, because I use this in different places and my son had a revered. The Grados with the 3.5mm jack are so good that you better listener is my humble experience only in at least 3-digit euro range. The sound is crystal clear and I hear out details that I have been part of many Senheiser- or Beyerdynamik- or Sony or Panasonic or, or, or never. Moreover, the neutrality of votes is better than many other phones. Mach also needed something forth. The only weak point is that the small transducers are easily broken when you drop provided from the handset. However, this only comes after years ago, because until the adhesive becomes brittle then. With normal treatment without "torture" - I call the just anyway - is unlikely to happen that. If it happens, you can bring the technical expertise with a little fine, then they drown as ever. :)
