This is my first review here.
What I want to say is this is the best headphones I have ever owned. ( I know they are in budget range,still they are the best I could afford)
So I took care of them like my babies, never let them tangle or anything. I go on buses and trains a lot and most of the time I wear them are as latter mentioned places.
I bought these from ebay with original Dunu warranty for 1 year.
After 8 months the left earpiece stopped working, contacted Dunu and got a replacement.
But after 4 more months, the cable seems to break from the corner of the metal earpiece.
really disappointing with their cable quality.
other than that sound quality is great.
I have own the Dunu tridents for about 4-5 months, and about a week about, the left ear suddenly stopped working. I left them on my desk for the weekend, no spills, or anything touching them. Now i did dunk them in water about 2 months ago by accident (tl;dr hung on my neck and fell into my cup or water), but they worked fine after that until now. I tried drying them by putting them near a heater but that did nothing. I bought them from ebay, so maybe that plays a factor. Overall, i would recommend them if they lasted a bit longer, but they were pretty cheap, so, i don't know.
