trying to start making the transition to wireless (got a new iPhone 7). I'm looking for suggestions for some bluetooth portable (read: something that can be stowed into a messenger bag) over-the-ears (preferable, though I have big ears) or on-ears cans to use with my iPhone. Right now I have Sennheiser HD598se for home use and VSONIC GR01 IEMs (a TWFK IEM) for portable use. I'm getting my old (shorted-out) Fischer Audio DBA-02 (another TWFK IEM) modded to MMCX, so that I can use them with a MMCX bluetooth cable (I bought the BT cable used on the Advances Sound Model 3).
I listen to a lot of classical music (classical, romantic and modern) and then a variety of other stuff, incl. electronic and ambient, but also some folk and pop.
I gravitate toward detailed/transparent, energetic, aggressive IEMs with tight (but never bloated) bass; I don't like when the range is muddied in order to give the sense of "better" bass. I love (and am used to the) the clarity, analyticity, transparency, and crispness of the TWFK IEMs; they have sparkle without sibilance; great-instrument separation; the bass is always tight, controlled, quick, detailed, and well-extended. I also like the wide and open sound of my Senns.
My worry: Given that I'm used to this sort of detailed IEM sound, I'm worried about getting a headphone that will drop an unbearable veil over everything. I recognize I probably won't be able to find anything within my budget ($50-$150) that can compete with those IEMs, and, in fact, maybe something slightly bassier than what I'm accustomed to might be good in public/louder places? But anyway, that's the sound signature I'm used to. Any suggestions?
