Pros: Style, sound, soundstage, detachable cables
Cons: No carrying pouch
The WS-99 are Audio-Technica's top of the line headphones in the Solid Bass line- and rightfully so.
These headphones are among the best that I've heard.

Build - The WS-99 shares a lot of its overall design with the the mid-level WS-77. However, the parts and quality of the WS-99's build are much, much above that of the 77's.
The outer circles of the cups are much more high-quality. The ridges are more deep and give the headphones an even better look when hit by light at any angle. The ridges are actually quite sharp. They're able to cut through a shirt if rubbed on it. Learned that the hard way. They're made out of a high quality what I believe to be aluminum. You can easily see Audio-Technica's Dual Chamber technology with the way that these are designed. Really impressive to me.
Under the pads is mostly aluminum, contrary to the WS-77's plastic.
The headband is almost identical to the WS-77 in terms of shape. It feels a little more sturdy, though. The padding on it is very soft and plush.
The pads are a bit more soft than the pads on the WS77, which contributes to both comfort, and, for me, a higher feeling of elegance.
Comfort - Simply excellent. The WS99 is easily one of those headphones that you can sometimes forget that you're wearing.

Sound - The WS99 has a bass heavy (obviously) sound signature with a slightly sparkly lower treble. The WS-99 shows to be a headphone that can be used with whatever genre the user throws at it; from electronic, to jazz, to classical and beyond.
Bass - As with all of the Solid Bass headphones from Audio-Technica, the WS99 delivers controlled, impactful, and punchy bass. While it does not have as emphasised of bass as the V-Moda M100, the WS-99 is still a good bass-heavy headphone that I think anyone can enjoy. I prefer to use these headphones with EDM and jazz due to their excellent bass response.
Mids - There's a little bit of recession going on here. It kind of reminds me of the midrange recession in the M50, but just not as severe. Much less recession than the M100 also. Vocals do sound quite natural still. Female vocals seem to have a little more energy when compared to male vocals with these.
Treble - The WS99 has a well-extended, detailed treble response. Lower treble is much more sparkly than the WS-77, which gives it a more natural and powerful sound in comparison.
Soundstage - As with the WS-77, the soundstage is very good for a portable headphone. Positioning and space is excellent for a portable. In comparison to larger headphones, like the DT770, though, it obviously won't compare well.
Overall - The WS-99 has style, build, and a powerful sound. While it has a less warm sound than the WS-77, both consumers and audiophiles alike should find these headphones to perform exceptionally well.
