Easy to install and pay attention to how the end go on and pointing the right direction. And still have to pay extra to sent back a return . I have to hold my phone in my hand when I run. I have tried several solvents to remove the stick and cant. My only complaint is that the product is not as sturday as I assumed it to be, but I do realize it is great quality for the price although it is not gym quality. My only concern is if the loop is strong enough. The buds themselves were new as well, so there wasnt any dirt or anything on them. I can wear them all day and feel supported around the arch. this sound Quality is incredible for headphones costing this price. My first pair held up for many, many years leading me to consider their price point very reasonable.
