Best pair of ear buds I've had yet! Great bass sound is what stands out to me along with superb for in to ears. Great over all sound for music in gym while working out. Can't find a better sounding pair for the price.


These are incredibly comfortable! Not to mention convenient! I'm so happy to have them for working out! It's wonderful to not have cords while I'm running or working with weights


The headphones have great ear inserts that are flexible and stay in the ear without any worry of them falling out. The sound quality is very good and I have used them while working in the yard and working out at the gym and I have been pleased.
