Question: Are the ear cups large? I like the ATH-M50 from AudioTechinca, but they press down on my earlobes and I'd like something that lets my ears "open up."
Document: I was looking forward to these headphones after reading rave reviews from audio magazines online. I've always been a fan of AKG sound equipment so getting a pair of their high(er) end headphones was something I aspired to.I received the item and it arrived in a well made heavy cardboard box, very substantial. After unboxing, I noticed that the headphones were very well built. With the sizable drivers for each ear, the cups were larger than I was used to but fit well over my ears.
Don't expect them to settle properly from just the clamping force.The 50mm drivers give big, deep, round ear cups with room for large ears without pinching or folding. The cushions are covered in extra-soft synth leather and breathe well. Combined with the overall reasonably light weight, these are very comfortable to wear even for hours at a time.Materials and construction quality are excellent, and the design is sharp but understated and attractive.
This may explain why i like these headphones for acoustic music at low volumes.Sound stage is open - instruments are playing on both sides of my head and slightly in front of me. I hate when headphones beam sound into the center of my head.AKG 550 are VERY comfortable: ear clamp force can be adjusted by bending the steel headband.Ear pads are soft and fit over glasses without any problems.These are large headphones, but they fit nicely in my regular sized backpack.
Though I've never had a pair of in-ears that sounded this good (I have some really nice Etymotic and Klipsch in-ears).Also, I guess that wasn't the last thing. I'd like to note that a few other non &#34;open&#34; sets I've owned (mainly the Sennheiser HD280 and Bose AE2) have this ... pressure from being _too_ tight (and dead) in their sound.
I'm an average sized man, 5'9 1/2&#34; 155 lbs, hat size 6 7/8 to 7 and I cant get a reasonable fit. The headphones are too big. Without a firm fit on the ears there is no bass. With the headphones on and my fingers pressing the ear cups into my head, the phones sound terrific. But no one can listen to headphones that way. If you are my size or less, do not buy these headphones!
ATH M50 by audio technica is one of the most highly regarded sealed, low-impedance cans, along with the Senns HD25s, but i wanted a set of cans that rivaled the sound stage of an open-back set of headphones. So these cans deliver the sound stage? sort of. The sound stage is good, really good. In fact, they're the best I've ever heard from a closed-back headphone.
It's not overpowering, but I'd call it natural throughout a wide range of styles. Some bass-heavy electric (not electronic, just amplified) music sounded incredible. You can sort of feel the shockwave, but the bass is rumbly, it's very crisp and authentic.One thing I like about these versus my 702's, is that the closed-back design really lets me get close to my music.
nice to have over ear headphones that have large ear areas and do not require batteries yet seem to protect from outside noise and not leak noise for those around me. Not too hot with time like another pair I have (that requires batteries for noise canceling). Yeah! a home run!
I enjoy these as much as my Sennheiser 598s and Shure 500 PTH in ear monitors. For a closed head set, they have a large sound system and pretty good sound isolation.I like the large comfortable cushions. Almost as Bose QuietComfort cushions but much larger. Feels better than the velour cushions of my Sennheiser 555 and 598.For my listening preference, I like my Shure 500s the best for their balanced overall sound from bass to treble. Sort of my reference for comparing all other headphones.
I'll update this with a real review later, but suffice it to say that I love everything about these headphones besides the extra long cord.I think I'll be getting something like the large black cable turtle (http://www.amazon.com/Cable-Turtle-Organizer-Large-Color/dp/B0021JMV4Q) to better manage the cord when walking around.Besides that, though, the fit is excellent, the comfort is great, the sound is incredible. Well made and stylish.
Answer: I measure a 4 3/8" wide Can, and the inner cup being 2 1/4" wide and almost nearly an inch deep. My ears are not small, but they feel like they each have their own rooms with these on. Cups are amazingly comfortable, with a softer-than-soft feel. My only complaint is that the piece that sits over the top of your head feels heavy and relatively unforgiving....but nothing your average baseball cap can't cure. Hope that helps, and good luck!
