Sadly, my E30 died yesterday only after using for one and half months. Problem is: no sound coming off my the right earbud.
I'm located in Kolkata.
If anybody knows the RMA procedure & the location of their office (or service center etc) Please let me know.
Update: Today, I've submitted E30 to Acro Engineering, Kolkata. They have told me that I'll get replacement, and as it was not in stock with them at that time, I'll get it after the puja session is over (ie.e after 10 days). And they will call me when the replacement is ready.
Update: They have asked me to contact them after Durga puja, and when I contacted them, they have said it is ready. Got new E30 from them.
Good RMA experience.
