Definitely do what the title says! once you put these in you cannot hear anything, which is great at the gym! would highly recommend to anyone who likes listening to their music without outside distractions.
When I go for headphones I go for loud and clear and that's what these gave me couldn't even hear my boyfriend ;) they were also fairly priced. I would with out a doubt recommend these to anyone who when they listen to music they listen loudly!
These are perfect and they cancel out noise well. They're a good price for the quality and aren't too big for your ears. I bought them in an airport and they're better than most earbuds I've used. I like in ear headphones and I definitely recommend.
I love how once I place these earphones in my ear, they stay there and don't budge until I intentionally pull it out. I love the clarity and quality of the music and the way it can cancel out any outside noises.
