I was concerned about these being a low quality copy of another brand, but I was delighted by how well they held up. The ANC does a decent job doing what it?s built for. My previous generation Minnetonkas lasted me three years of intensive usage. Soundwise, they are fantastic, though durability has to be proven. I am reasonably handy. Sound is nice. Consider me a convert. Theyre amazing. Don?t ever buy! Quality just isnt good enough for what Im paying for!
