I used this speaker for a week before this review. Most of my use was during skiing, in the pocket of my snow pants, right next to my phone. It may have been the way that the speaker was placed in my pocket, but by the third day the cable had already begun to fray.The sound is fantastic and very loud, even without the bass resonator open.You will not regret buying this speaker, nothing else sounds this good for 20 bucks. I removed one star for the cheap cabling and lack of a usb to wall adapter to charge the product. 

Question: What happend whit the sound?
Answer: The sound is fantastic and very loud ,
