These headphones will be used with my iMac and my audio interface (30 ohm output) for both home recording (guitar) and general listening. Since I will use them also for tracking isolation and lack of leakage when recording with a condenser mic is important. I have idenified a number of candidates based on an evaluation of the flatnness of frequency response, whether they were closed or semi-open, acoustic isolation specs, weight/comfort and qualitative comments from the internet. These were the candidates that I evaluated:
AKG: K 701, K 702, K 550, K 271 MK II, K 240 MK II
Audio Technica: ATH-ESW9A, ATH-A900, ATH-M50
Beyerdynamic: DT 880, DT 1350, DT 770
Sennheiser: HD 25-1 II
Shure: SRH940, SRH840
The flattest in terms response seem to be the K550, DT 880, AH-D200 and the SH940s...
In terms of acoustic isolation the Shures and the AKGs provide more but the Beyerdynamics and Denons attenuate somewhat.
I was surprised that many of the AKG Studio Professional audio headphones did not appear as flat as the k 550s. The K 550s are in teh consumer line and are not marketed for audio engineering. So the fact that they appeared flatter surprised me a bit.
I would your input in recommending a pair forr my listening application. I also would appreciate advice as to whether or not I will need an amp to achieve volumes considering the impedence of my computer and my audio interface? What I can't really tell from online reviews is the quality of construction, fit, sound stage and wearing comfort. So any distinctions here would be welcome. Lastly, if there is a pair that I should consider that are not listed (no open models please) I would love to hear your suggestion.
Explaining "why" is always welcome!
