I've been using Sony in-ear phones for a little over a decade now and there's been quite a worrying pattern to my experience, where the XB90EX comes in as one of the "awesomely great" generations.

Let me quickly go through my history of experiences with Sony in-ear phones (it started with the white MDR EX-70) so you might understand what I'm getting at:

MDR-EX70: awesomely great, first in-ear phones I've ever had.
MDR-EX71: about as good as the EX70, including the white cables that turn an ugly yellow-ish colour after 2 years.
MDR-EX85: were not as good as I expected them to be, but a decent improvement over the previous.
MDR-EX500: GREAT! These things blew me away totally. Whole new sound experience.
MDR-EX510: HUGE disappointment (meager bass) at a ridiculously higher price point. The most ridiculously-priced of all!
MDR-XB90EX: ABSOLUTELY AMAZING and yet almost half the price off of what I paid for the EX510!

See the pattern? It seems that the quality jumps up every other generation or so. Thank God my 510s held up (until I lost them just two days ago.. hence I got the XB90s) and I skipped the ridiculously overpriced XBA line. The XBA line does NOT sound worlds better than the meager 510s I had (In fact, the XBA-2 was the most decent sounding of the XBA line, on par with my 500s).

WHAT a HUGE improvement these XB90EXs are over ANY of the in-ear models I've ever had (or tested)!! Even the Sony Store salesperson recommended these over the ridiculously-overpriced XBA line. The drivers in the xb90s are 16mm -- larger than any of the others (typically at 13.5mm). It makes for a world of difference. The price point is an absolute treat as well. Cheaper than my 510s (MUCH cheaper!!) and just a little more than what my 500s cost me.

After reading a review on Head-Fi.org that these had the best bass for IEMs (in-ear monitors), even better than Shure's SE846 (which costed me ~$1k), I decided I had no choice but to purchase these, if for no other reason than to compare to the more expensive in-ear monitors (IEMs) I own.

Without going into a long, drawn out review...

In short, I will say the Sony MDR-X90EX was the clear winner in the Bass category (with a lots of clarity to boot), when compared head-to-head against my Westone UM3x RC, my Shure SE846, and my Westone UMPro 30 (to name a few).

I compared all the monitors through my Fiio E17 K Alpen 2 Amplifier/DAC, listening to 'Mirror Maru' by Cashmere Cat (an excellent track) via Spotify's highest Bitrate sampling, followed by various Deep House tracks on the Monika Kruse station on Spotify.

Before owning the Sony MDR-XB90EX, my favorite IEMs were my Shure SE846s. However, after listening for hours with my Sony MDR-XB90EX, I'm having a hard time deciding which set truly sounds better.

I've decided although Shure's SE846 falls short of the amount of bass the Sony MDR-XB90EX provides, Shure's sound signature is tighter, more flexible, and overall less artificial (to me). They are also less fatiguing and more comfortable to wear for longer stretches of time.
(Now whether or not they are 10x better for ~10x the price is debatable.)

That brings me to my next point...

Although Sony's MDR-XB90EX earbuds are undoutedly worth every penny, they are not perfect.

Here are some noetable cons (in my opinion):

1. They are not as volume sensitive as any of the 'higher-end' IEMs in my repotoire; I had to raise the volume ~20-25% higher than my other IEMs to 'make the beat drop'.

I've been using the Monster Carbine and Beats Tour before I decided to purchase this earbud.
My beats decided to give up on me so I was looking for a good replacement, and after spending weeks on many different review sites, amazon, and other site including head-fi.org
After a VERY long extensive search, I decided to purchase a Sony earbud.
These XB90EX are imports from Japan so it is very difficult to find a legitimate review of an audiophile online, but I stumbled upon a forum post in head-fi.org which talked about these which definitely helped me make up my mind.
Now, I've been using them for a little over a month and I cant ever go back to my Turbines.
The Sub Bass of the buds are very booming, which feels like a subwoofer in the buds. Note that I said sub bass.
It's a booming sound which I haven't heard in any other previous earbuds I've used before.
The ones from monster, and my older Radius DDM 2 (HP TWF21) which all promises superior bass sounds like nothing after using these. They are a bit big and sticks out of your ears, but the sound is very premium for an IEM.
the cables are also flat designed and definitely feels like high quality materials, but they are a little thinner than the tours.
So that was a short review from a non audiophile, I can promise you that these blow every other earbuds away that are in a higher price range, including the monster carbines, beats tour and the DDM2.

Definitely recommended if your into EDM, Trance, Hiphop, Dubstep music... You wont be disappointed esp if your previous earphone is a generic one like Apple earbuds.
