I know Razor is notorious for a lack of durability. I am really loving the orange switches and they suit me the best. I?m a Certified Jazzercise Instructor and Ryka nailed it with this design. For the record Ive been driving them with a Schiit stack and also an xDuoo Link. The adhesive is sticky, but definitely not the same category as true 3M adhesive for similar products. Depending on your needs, getting these little guys for the great price seems worth it. Im on my 5th pair of these and I absolutely LOVE them. Now I dont have to worry about losing this teeny weeny headset! It sounds better than my cars speakers. The fit is a little tight on my head and my MacBook Air has trouble switching them on, but once on, theyre fine.
