I recieved the Sony XB700's today and have played with them for a while. Wow, these are really great already out of box with my Sennheiser HD 212 Pro EQ profile I could hear these are in a totally different league. I'll try to compare them with my experiences from Sennheiser HD 212 Pro (deep boomy bass, bright "skinny" sounding highs, recessed mids), AKG K 518 DJ (aka K81 DJ) (VERY PUNCHY upper bass, dark/warm sounding, smooth highs, decent mids, typical closed headphone sound), ATH-M50 (controlled midbass extension, great soundstage, clear/sharp highs and great smooth mids) and DT770 Pro (somewhat controlled deep bass, lacking midbass, decent mids & highs).
Bass
These headphones have the bass I'm looking for. It's there between being punchy upper bass / boomy lower bass compared to AKG K 518 DJ (most punchy, 90~150Hz bass focus) and Sennheiser HD 212 Pro (most boomy, 40 ~ 70Hz focus) while quantity being about same (ie, among the bassiest you can find, more than ATH-M50 and a bit more than stock DT770 Pro). It's a bit more "soft" than punchy tho, a bit more focused towards the below 90Hz or so bass and it extends deeper than any other headphone most likely and it did play very deep bass say around 30Hz a bit more clear and loudly than the HD 212 Pro but those do suprisingly well for deep bass too. There's relatively small emphasize on the very outmost upper bass around 120~150Hz. An easy recommendation IMO for bassheads because they can handle a bit of both types of bass depending how you EQ them and btw these responds very well to EQing (unlike DT770 Pro) but more on that later.
Mids & Highs
This is where I thought HD 212 Pro lacked the most, recessed mids and very bright and "thin" sounding highs and where I was looking for the improvement while keeping the bass of HD 212 Pro. I liked both ATH-M50's mids and highs and AKG K 518 DJ as well but M50 lacked bass quantity and K518 DJs lacking deep bass. Sony XB700 handles the bass perfectly but also handles mids and especially highs extremely well. The highs are very "full" sounding and suitable bright IMO, far from HD 212 Pro levels and not quite as sharp as M50, just about right IMO to not cause any ear fatigue and still stand out from the deep bass output. The cans have only a slight emphasize in the lower mid range 150 ~ 500Hz or so, but 1kHz - 4kHz sounds very nice and "full" still, unlike HD 212 Pro, giving them a quite smooth transition from bass to mids without drowning them too much (depending on how much you've EQd low frequencies).
Soundstage
These are better than the average closed headphone in soundstage but not quite in the league of M50 so something between average to best. They do however have a very "spacious" sound signature, most likely to the big drivers (50mm) and the rather big airchamber the soft cushions create, this makes them sound a lot more towards open headphones than especially small "on-ear" closed headphones. Playing a round of Unreal Tournament 3 I could more easily distinquish the different sounds from each other as overall it sounded way more dynamic, (weapon noise or running over a guy etc noise effects etc just popped out more clearly). Sound positioning was also decent, not the very best but still better than most closed headphones I'd say and it was possible to hear from which directions the sounds came from.
Comfort
I thought the big size and 295 g weight would be a problem, but it seems the way it's designed, it really doesn't feel any heavy at all, in fact it feels like it would be lighter than both M50 and DT770 Pro to me. The clamping force out of box is just perfect. The soft pads are so huge they're like the size of CDs and there's plenty of room for your ears inside and like many others already have said they are prolly among the most comfortable headphones to wear. I thought sweat would be a problem but I was positively suprised, despite I got 28C in my room, they only got a bit warm after 1hr+ of use and only very slightly wet/soaky altough the pads are so big they easily absorb up the sweat, leaving your ears dry.
EQing
I've never heard a headphone that responds this well to the equalizer I'm using with kX Audio drivers. If I listen closely at some frequency settings and certain values, I was able to notice a slight difference even from a 0.1 step change! O_o (yeah, kX Audio driver's 10-band EQ let's me adjust in 0.1 increments). Usually I use a gently shaped V-curve but with these headphones the V-curve became far more closer to a flat line apart from being a spoilt basshead I ofc boost the low frequencies a bit more. Due to the well sounding mids and highs I want to hear these a bit louder than what I wanted to with the HD 212 Pros as the XB700 responds so well to tweaking especially lower midrange (250 - 500Hz) and 1 - 4kHz range.
To Summarize:
The good:
- Tasteful BASS, can be both boomy or punchy depending on how you EQ it. Non-EQd it's in-between.
- Very good full sounding mids and highs for the price (mind the recent pricedrop, now you can find it for ~$75 / ~65 EUR! at popular etailers)
- Very sensitive to EQing, makes it easy to get the sound YOU prefer
- Comfortable
The bad:
- Short cord
- Pads can get a little warm
- Not perfect ambient noise cancellation and leaks a bit sound
The only problem for me with these headphones is the short cord, I'm gonna buy an extension prolly tomorrow. Well possibly it would be good if it had slightly better ambient noise cancellation. But I'm very happy with them, it's like I got what I was looking for, I got Sennheiser HD 212 Pro's deep bass with AKG K 518 DJs "fullier" mids and highs. The Sennheiser HD 212 Pro I paid 43 EUR for and AKG K 518 DJ I paid 49 EUR for, the XB700 I paid
66,60
EUR for, getting the best of both worlds.
IMO this is a very easily recommended headphone for any basshead, I prefer them even over DT770 Pro/80 and I think it has mids and highs that reminds me slightly that of M50 making them really an awesome bang-for-buck ratio pick for any bass lover out there.
