I previously posted this in the B&O H9 thread but realized I was too focused on the B&O and am coming to a more general thread to ask for an advice (and some extra details about what I'm looking for).
First of all, I have long been a basshead. Never to the extend of losing the general feeling of what the music was meant to be, but I do love deep and controlled bass. Heck, I even build an IB subwoofer with 4 sub of 15" with dual 1000w voice coil for my 5.1 sound system in the living room as I can't afford a home theater room.
Lately, headphone wise, I've been using some PSB M4U2 and appreciate them even if from the moment I had them, they had some trouble. They were gifted to me by a generous member here that didn't want them anymore as 1 side wasn't working. I managed to fix the wire inside the left driver that was broken, but they also kept sounding slightly recessed on that side compared to the right side.
I've now grown able to offer me some luxury and even thought I liked the sound of the M4U2 and self amp feature for when I use them only with my S7 edge, I wanted to go wireless. So last monday, I ordered some H5 thinking the small IEM would be great for various situation and maybe even some training. Sadly after trying them for under 15 minutes, I couldn't bear them at all.
I have very small ear canal (kid sized from what the audiologist told me). I have trouble wearing the H5 even with the small sized tip. The mids and high seemed great, but the bass was also almost unheard, something I can't accept. They also had something annoying: the wire between the 2 iem transmit some strong signal to the driver as soon as you rub it and during the 15 minutes I was trying them, I had constant quick but annoying stutter, kinda of micro disconnect a fraction of a second, at least once per minute.
Considering I knew I have never felt right with IEM (but wanted to give it a try) I wasn't surprised about the trouble I just faced and will be getting rid of them next week.
But I'm here again, looking for something with the best sound quality I can get while being wireless and was wondering how you'd compare some of the headphone in the list with the M4U2 and H5 I experienced. The ANC isn't an absolute must but a good positive. I'm looking for something that would offer the equivalent or better as the M4U2 in term of sound quality. Price is not a major factor atm as if one truly beats all the others I'm ready to spend a nice amount to get them, but if there's not much reason I won't throw money away like there's no tomorrow.
Thanks all for the help!
