Pros: good isolation, warm, friendly mids, bargains can be had
Cons: Shure cables. God I hate you Shure for your cables.
I like this phone so much I am onto my second pair. Are they perfect? No. Are they the best IEM for the price? Unless you get them at $79 like I did the second time, no. Do they have a good soundstage? Not really. Are they durable? Like a boat made of paper.
But...Do they isolate well? With the Shure olives, hell yes. Do they have delicous, buttery mids that I could and have listened to for hours on end? Yes. Are they comfortable and easy to insert/remove? Definitely.
If you like those things, consider these.
