TechElec SP-X Sweatproof Bluetooth Headphones are well made. The construction is sturdy. The headset is comparable to my more expensive major brand headset. I like the silicone ear piece that allows the earpieces to stay in place even in vigorous workouts.  The sound is good.  Great for the price.  The range of the headphones is 45 feet, which is great because you don't have to have a phone in a pocket while working out. As far as being a set of buds for the gym they are great!
