Very sturdy product. EDIT: Just wanted to add as of Oct 2020 this unit is still going strong. O fone também possuí a opção de som ambiente, no qual amplifica o som ao seu redor possibilitando escutar música e escutar o som ambiente ao mesmo tempo. Another review said he had to wield and so forth due to cutting it and I dont know what he did wrong but theres no need to wield anything. Pervious review:Comfortable to wear and Is high quality, not so bulky. Great little shoes for my tiny feet Yes I followed directions. If youre a college student looking for a speaker for bumping, this is for you. The magnet wouldnt charge at all so thats a down fall you dont know when its charged. PROS: Tested on transpacific crossings - over 28 hours of flying in a 787.
