I dont lift much over 200 lbs. This works perfectly. Bought these for $20 and they are great for the price. I find myself kicking them off without even thinking. Not only are these going to be functional for what I need but they are so darn cute! ✅ Tienen sensores que paran la música cuando te los quitas en ambos drivers y funciona de escándalo. They were NOT the same. Im also an instrument builder - ok theyre cigar-box and whiskey box guitars and ukuleles, but theyre fun! I was convinced by other reviews that the AD1000x was worth the $100-$150 increase in price. I also LOVE the fact it’s so long compared to the original!
