Review on TREBLAB XR500 Bluetooth Headphones: Ultimate Wireless Earbuds for Sports, Running, and Gym Workout. IPX7 Waterproof, Sweatproof, Secure-Fit Headset. Noise Cancelling Earphones with Mic by Brad Cao

Have been using this Treblab xr500 every day for the past 5 months. After that I am now confident that I can give a proper review. I'm an avid CrossFit fan who hates the music that plays during workouts. Despite sweat, dirt and heavy traffic, they sit very comfortably in my ears. In terms of sound, you get what you pay for. The base is low but seems to suppress the mids and highs. The mids and highs are a bit muffled, and I feel like the stock Samsung headphones that came with my Galaxy S5 are better balanced. I'm passing them on to my wife and will be upgrading to something else from Treblab.
