-My previous can of choice. Excellent isolation, sound great, sould survive a nuclear holocaust, reasonably cheap.

-Get the velour pads - the pleather standard ones fall apart in a few months of heavy use, and the velour ones are more comfy.

-If the V6 are cheaper, get them - they're identical to the 7506's (except the plug's plastic on the V6, metal on the 7506).

+#### Sennheiser HD25
75
+My current headphone.
76
+Excellent isolation, excellent sound, easy to drive, largely bombproof, replaceable parts, available everywhere.
77
+Only had these a few of years, so I can't comment on their long-term use, but mine look brand-new.
78
+Might be a personal preference, but they sound genuinely excellent. There's a spike in the response around 9KHz, but it's not apparent to me - I can't stand bright sounding headphones (I binned a pair of Grado SR-80s because they were too bright) so it probably won't bother you either.
79
+I like these so much I own 3 pairs.

82
+My previous can of choice.
83
+Excellent isolation, sound great, will survive a nuclear holocaust, good value, available everywhere.
84
+My pair lasted about 15 years of genuinely shocking abuse - if you need a headphone that will absolutely definitely work no matter what, get a pair of these. They sound genuinely good, but the bass response is a bit lumpy and loose in places - if you're listening to anything except house/techno/DnB, though, you probably won't notice it.
85
+Get the velour pads - the pleather standard ones fall apart in a few months of heavy use, and the velour ones are more comfy. You'll lose a bit of isolation, but they improve the lumpy bass response slightly.
86
+If the V6 are cheaper, get them - they're identical to the 7506's. (Well, the 3.5mm plug body's plastic on the V6, metal on the 7506. If you manage to break the V6 plug without the aid of a vice and sledgehammer, I'll buy you a pair of 7506's myself).

89
+#### Beyerdynamic Byron
90
+The best sounding in-ear 'phones I've heard that I'd be willing to subject to the abuse of every-day travel.
91
+Reasonably flat response, lightweight, non-microphonic cable. Can't fault them at all.

93
+#### Soundmagic E10
94
+My backup in-ear 'phones.
95
+Sound great most of the time, but the bass response is can be overblown. Dirt cheap, though, and depending on what you're listening to the bass response might not be an issue.

+#### Sennheiser HD650
99
+Incredible sounding headphones. Very well balanced, airy, comfortable. Very expensive, though.
100
+These are very high impedance, so they **really** need decent amplification to make them work properly.

+### Headphones: Amplification
103
+My goto is Objective2 / ODAC stuff - JDS Labs and the now-defunct Epiphany Audio. I hear the Topping gear is also very good.
104
+There's a lot of snake oil in headphone amps, so be careful. Look for actual measurements in reviews.
105
+And if your headphone amp has valves in it, then you need to have a word with yourself. Seriously.
