Id say I have a flatter arch than most so I might have misunderstood when it said that it provided arch support. I want to say first that this speaker rocks! Aún así no se siente que falten las demás frecuencias y el sonido está muy detallado. Assembled by a single (inspired) person in 30 minutes. After opening, I was like, "these feel pretty cool! Woke up at 2 am and checked, the speaker software was updated. I never expected I would like the mousepad the most. I normally love FitFlops but this pair I do not. - This dresser was SUPER easy to assemble. Beautiful love it!
