I have owned 3 pairs Boss QC noise-cancellation headphones (QC15, QC25 and QC35). While they are generally considered to be a reputable brand, and their software/firmware might be the best, their hardware design is NOT. I noticed that their QC15/25 has a major flaws on the battery compartment design cause its wiring prone to wire fatigue and as a result it will inevitably end up with a broken side. This is very well known in the community.[1][2][3] And after warranty expires(usually 1-2 years), Boss charges you $100 for a refurbished replacement (required that you sent your broken headphone back to Boss before you get your replacement) instead of just fixing yours (which should be much cheaper).
