Quick Impression: Sony MDR-7550

I like them but not my favorite.  To me the 7550 are more neutral than the W4 but lacks the instrument separation the W4 possess.  W4 also has better/more forward mids.  I really liked the FX700's but the bulky housing ruined the fit for me.  The 7550's are way more mellow and less sparkly and bass hits softer going from memory.  My favorite universals have been the JVC FXD series since they've come out.  The FXD80's are something else.  It's more colored then the 7550 but does it in a good way.  Plenty of detail but adds a fun factor I can't resist.  

 
The FXD80 and the 7550 both seem very typical of their respective categories; consumer and professional monitor. They both have their appeal :3 I'm sure that eventually JVC will put out a reference version of the carbon nanotube design though, which might be the best of both worlds.

What I really want JVC to do is fix the FX700 and bring out a new flagship. The bass needs to be more controlled, treble should be further refined. The cable also needs to be extended, possibly made detachable for its price range. The mid range needs to also be more upfront and not recessed  behind the treble and bass.

That would be pretty awesome.  Also a circumaural version would be nice too.

So DannyBai how are you enjoying both the UHA6MKII and the Miracles? Do you roll Op-Amps? I find it very beneficial for different sound-signatures and synergy/mood preferences. Really enjoying my 1Plus2s though :)..

circumaural version of 7550? isnt that the cd900st?

I meant for the carbon nanotubes.  They only have the iem's and supra-aural version currently.

I just ordered the UHA with the with the standard op-amp.  I was close to getting the 627 but after reading a little that's out there, decided against it.  I'd get the 627 but what's all involved when switching out the op-amps.  I do not have any soldering gear and don't trust myself digging too far deep into messing around with gear.  Really looking forward to it and comparing it to the Dragonfly and RX MKIII.

lol DannyBai they are pins so you don't solder anything. You just use a pair of tweezers or a pin extractor to easily switch out Op-Amps. Just make sure to put them in correctly or you could risk damaging the chip. There is a marking on each chip that will indicate the appropriate method to put it into the board. I actually switched out my Op-Amps yesterday. It took only 2 minutes to do and is very easy. Just don't be reckless and its a breeze. I ordered a pair of Op Amp 627AP from Mouser on Nicks recommendation (owner of Leckerton Audio). It seems to be the cheapest option available and is a direct fit.

Just insert them into the pin holes without bending the pins into the UHA6 board and you are good. For Op-Amp 627AP you will have to slightly bend the pins inward to make them point straight down as they are just slightly curved outward ^. I did opt to buy a pair of 8610 from Nick (was a $10.00 upgrade) and bought a pair of Op-Amp 209 from him for $20.00. All worth the money IMO and offers great versatility. No soldering whatsoever :). Looking forward to your impressions against the MKIII. I heard this amp shoots rather close in comparison with that amp. Kinda scary considering the MKIII is more than double its price-point.

Thanks lee.  I went and ordered the 627 from mouser and sent Nick a message to order the 8610 also.  I appreciate it dude.

No problem, just be sure to at least use a pair of tweezers when extracting the chips. I'm actually preferring the tweezers even to my DIP extractor. Seems I can just slip the tweezers under the chip and gradually wiggle it out of the board without bending the pins at all.

Well I do have a pair of tweezers so hopefully I won't mess it up when I try.  Thanks for the tips.  This shall be fun.

Well I got my MDR-7550s earlier on and I must say I really like them. I even fell asleep with them in and my ears were just fine. Very soothing and good even at low volumes. I definitely feel this is an improvement over the EX1000 in the usability and enjoyment factor. I know people have made comments regarding the EX1000 being romantic. I know what they mean now. Although I thought the EX1000 was more along the lines of Cruella, bitter and cold as ice :wink:. Glad I wasn't so stubborn to not give these a chance. I had really liked certain aspects about the EX1000s and these IEMs manage to do it without the flaws. A nice upgrade over  both the EX1000 and FX700 :).

Glad you like it Lee :)

They are very relaxing and I used mine falling asleep alot as well. Signature wise they were close to perfect for me, I just wanted a smidge more treble.

So then you may want the EX1000s? Not sure if I'd call it a smidge more of treble though :p.

What Lee? Given your hatred of the EX1000 I'd have never guessed you'd start dating her sister, who's nearly the same yet tends to be more laid back. LOL. Glad you're enjoying them.
