Durable, Sweatproof Over-Ear Headphones for Intense Gym Workouts

Many existing headphones, even premium ones, are not designed for the specific rigors of heavy gym use (sweat, intense movement, potential impacts). The user explicitly states a need for 'solid headphones that are sweatproof and don't fall off,' having experienced failures with Bose and Beats. There is a clear market for over-ear headphones that combine excellent sound quality with extreme durability, comprehensive sweatproofing, and a secure fit specifically engineered to stay in place during active workouts. The user's consideration of 'old sturdy stereo headphones and wear earbuds inside of them' highlights the significant unmet need for truly robust gym audio.
