Philips Fidelio L2 - Main listening headphones, I really enjoy them. I put a small pad on the headband because they were hurting the top of my head and replaced the earpads with sheepskin ones from Taobao. I used to have Brainwavz pads but I found them to be too large for the mid-sized over-ear form factor of the L2s. I tried EQing them using the standard correction files but I actually find I prefer them without any EQ. On the other hand, I prefer EQ on the ES10s, which are a little heavy on the mids without any EQ which makes them sound a bit muddled to me.
Beyerdynamic DT1350 - I bought these to replace Audio-Technica ATH-ES770Hs that I lost a few years back, as portable headphones. I really liked those ES770, and the DT1350 sound great (maybe better?) but I don't like the fit as much. They really sit directly on the ear and protrude a lot, which I find a bit uncomfortable, especially when moving my head around a lot.
Audio-Technica ATH-ES10 - Bought these after the DT1350s because I really wanted the ES770H style and I managed to nab these for around 70 USD shipped on Amazon Japan. Cleaned them up and replaced the super worn out headband and earpads (again with sheepskin ones on Taobao, amazing what you can find there) and they are better than new. I think I may actually prefer the sound of the ES770H but I really love the comfort of these for a portable. They sit on but also around the ear, are super compact, isolate reasonably well, and sound great to me.
Massdrop x Nuforce EDC3 - I used these for about a year for portable listening. I have always had trouble finding IEMs that fit me well, that don't slowly fall out over time or irritate my ears. Sadly these ended up irritating my ears as well. I ended up developing a chronic ear infection. After talking to an ear specialist about it and getting my ears checked out over a few weeks' time, the doctor recommended I don't use IEMs anymore as the skin inside my ear happens to be particularly sensitive and prone to abrasion. So I use the ES10s as my portable headphone of choice nowadays. Well, actually, since Covid-19, my girlfriend uses them for telecommuting
. She also prefers them to the DT1350 for the fit.
