I've never used headphones before.
only i used IEMs, then, i'd like to buy headphones.
but, i don't have any knowledge for it.
so plz feel free to recommend.
and i liked UE triple.fi 10 pro.
I've had meny different set ups over the last 20 years. The one I have now is by far the best I've owned.
Schiit Valhalla = $300.(bStock)
Schiit Bifrost = $300.(bStock)
Sennheiser HD650 = $400.
Does it matter if the headphones are open or closed?
What source(s) are you getting audio from?
Is this for music? movies? gaming?
Might I suggest you can spend less then $1,000 and still get some good audio.
Asus Xonar Essence STX sound card (Dolby Headphone surround sound), $175
Beyerdynamic T70 250-Ohm headphones, used $371, sold on Amazon.
Foobar2000 (free) for playing audio files.
Media Player Classic (free) for playing video files (at Codecguide).
I really know nothing about the Beyer T5 (or T5p) or how they compare to the T70.
Apple products come with decent audio support, but a separate dedicated DAC and headphone amplifier might have made the T5ps sound better (guessing).
I own 6 Beyer headphones and I find them all comfortable.
Currently I'm using my Essence STX with my T70s, using foobar and listening to Christopher Cross Sail Away, sounds sweet.
Another option is getting a (used $50) Xonar DX or D1 sound card and a Audio GD NFB-12.1 (dual DACs), connect them using S/PDIF Toslink optical.
The DX/D1 provide Dolby Headphone surround sound and using an external DAC can provide protection from a computer's internal electrical noise.
