The others are weak and wont hold up to any serious off-road walking, or will be uncomfortable. These are no AKG certified earphones but they get the job done. Im going to try to return it and see what happens. Not made for anti-slip. Manageable with normal socks on, but thicker "winter" socks will make the shoe more snug (with my feet at least). Then once I began assembly, I noticed the hinges for the doors dont align properly, the holes that are pre-drilled for the hinges dont line up correctly with the opposite door. Design:Sleek, cool look; matte-black finish looks awesome. I have had no problems with this shaver. This doesn?t work. Sad to see the quality of a brand I have been loyal to so diminished.
