1.yes in my opinion
2.Bass- Has huge impact and decent texture/speed without bleeding in to mids
Treble- One of the weaker points of the turbine, but thats not to say its bad just not great.
Mids- They are present even with the booming bass. Slightly forward to my ears but no where near what Shures can put out.
Soundstage- Don't expect a huge soundstage its a little above average.
For $35 dollars they are a steal and I recommend you pick them up. These are probably one of my favorite pair of entry level iem's and the first decent pair I owned. If you love bass and don't want to sacrifice mids these are perfect. I am however comparing these to the more expensive iem's I've tried and own now including the Heir 4ai, UE900, and Westone 4, but when you compare them to any $35 dollar iem they will destroy the competition.
