I use AKG K550 Headphones in the office, with which I am very happy.
I have Phonak Audeo 111 IEMs for portable use but they have developed a loose wire.
I've been really struggling to find portable closed headphones that are comfortable for big heads, with good isolation, low leakage and a fairly neutral presentation.
After lots of research I tried Sennheiser HD25-1 II, I was delighted with the sound but find them extremely uncomfortable after a short period of time so I gave them to my girlfriend.
I then switched to my IEMs before recently buying Beyerdynamic T51p headphones which are significantly more comfortable, beautifully made but they have a boost in the upper bass which I don't like and lack some detail compared to the HD25-1 II.
I'm now going to sell the T51P and am wondering whether to persist with headphones and maybe try the Philips Fidelio M1 or try other IEMs.
As comfortable as the Phonaks are I seem to get fed up with having something in my ear canal after a while when on long trips so I'm unsure about this.
Thanks in advance.
