If these models didn't both bill themselves as gaming ear gear, they could never be easily compared. The Moray+ is a thin and unassuming pair of earbuds (available in either black or white), and the Audio Specialist is a set of supra-aural cup-style headphones clad in black with brushed-aluminum accents (though, as of this writing, blue-, green-, and red-tinged "limited edition" versions are also available).
The Moray+ is very similar to the original Moray In-Ear Gaming Headphones, and so definitely positions itself as a go-anywhere pair. In addition to the small size of its zippered carrying case (1.4 by 4.9 by 3.1 inches, HWD), it comes with three adapters: one headphone-microphone Y-cable for PC use, and one each for the Nintendo DS and the Sony PSP. From ear to plug, the Moray+ measures about 4.5 feet, which will be sufficient for most applications (including talking on your cell phone, which Razer suggests as another way to multitask with the Moray+).
On the other hand, the Audio Specialist is less completely portable, though if you do want to take it somewhere, it folds up easily to fit in its 2-by-7.7-by-6.3-inch case. Its standard cable is an inch or two longer than that of the Moray+, but unlike that pair's configuration, the Audio Specialist's cable is not permanently attached. In fact, it's a micro USB cable (which terminates in a 3.5mm plug) that you can plug in or remove as you see fit. The PC Y-cable adds another 14 inches to the cable length—you'll really have to try to find an inconvenient arrangement for the Audio Specialist. Unlike the Moray+, if you want to use the Audio Specialist with other gaming devices, you'll need to pay extra (about $200 for the appropriate adapters or get the headphones as part of the $100 Negotiator bundle that includes the adapters).
The two pairs' gaming proclivities make microphones necessary, but each has a very different style. The omnidirectional microphone on the Moray+ is uniquely unobtrusive in that it's built about five inches down the right ear cable, and so subtle you can easily miss it if you're not looking for it. On the Audio Specialist, the microphone can also be hidden by coiling it within the left cup; just turn the dial in the center of the earpiece to extend or retract the mic boom. Nox has hidden the volume control for the Audio Specialist in exactly the same position on the right cup—an incredibly convenient place, and easy to adjust at any time. (The microphone mute switch is also there, located just where the USB cable plugs in, but wouldn't it make more sense to have it on the same side as the mic itself?) Razer hasn't hidden the volume control on the Moray+—rather, it hasn't included one at all. So if you're planning on using the headset, also make sure you have some way to adjust the volume.
