I plan to buy new earphones soon and I just plan for portability so I was thinking of IEMs. The earphones I currently use are Kingston HyperX Cloud IIs and Cheap Apple Earphones. I plan to bring it along and I don't really mind the sound isolation. I want a good upgrade under $100 I was looking at the Ostry KC06A and the Shure SE215. I plan for portability and even other solutions like getting a cheaper set of earphones and buying a good DAC or AMP. I have a flexible budget and im using a Zenfone 2 for music. I also want a more or less large soundstage and a balanced sound which can lean a bit to bass. Thank You! If you can suggest anything else please do even Over Ears or on ears as long as they're portable
