Pros: Crisp highs, deep bass, bass impact, accurate mids, looks amazing, price,
Cons: fragile, bass can kinda be boomy
These IEMs have an MRSP of $40. For that price they are not worth it. However, in many discount places, especially in Canada, you may find these @ $15 or less. If you find them for this price, grab them. I personally paid $10.
Sound is great for the price. They look very rugged and feel solid, I believe they are made from aluminum. The cord is also tangle free and feels very nice. Despite this they aren't the most hardy, they started falling apart and then stopped working a few months into use. And I was not harsh with them. The comfort is average, isolation is great. They include a small carrying case.
Overall, they're great budget IEMs for using in the gym or while being active. Just don't expect em to last forever.
