Tekfusion was a horrible night mare for me. They were damn heavy for ears and extremely harsh highs made me return the product within 2 weeks. JBL's INR 500 earphone sounded better, at least for my ears.
@pran.kumar, brother you made a big mistake. Tekfusion iem's are supposed to be used only after proper burn-in cycles.Burn-in process can be done by using the software on the company's website.I am a happy user of M edition iem for the past eight months. Rocking it with a Cowon J3. Hell it sounds familiar to headphones worth 5k
I've had a couple of friends who liked the earbuds, but then they had problems, and trying to get the warranty honoured was an even bigger deal, so they just gave up
