I was very happy with these the first 2-3 years: very nice sound and very good isolation.
Then the connection on the right earbud became loose, and it doesn't play unless it is kept at the exact right angle.
I tried everything to fix it: cleaning with a rubber q-tip, blowing it with canned air, replacing the cable, but none of these fixed the problem.
The only option now it to completely replace the right earbud, which is 60% of the cost of the new product.
For an item of this cost, I would expect it to last longer, or at least be repairable.
