V-MODA's CrossFade M-100 is more than just a stereo noise isolating headphones, these are for the serious audiophile that owns a headphone amp and knows what OP-AMPs are. They will should just fine on your mobile device or plugged into a PC but to really hear the dual-diaphragm 50mm drivers at their best you need a powerful source. Even the cabling is impressive with a built in mic and the ability to share your audio by splitting the signal into another set of headphones. If you are looking for high end audio and are willing to pay the price you should check out the article at Benchmark Reviews.
"To get the most out of the CrossFade M-100 Headphones you will be wise to also invest in a headphone amplifier. The sound output from today’s smartphones might be enough to crap out your average best buy $10 headphones, but it just isn’t enough to get a truly satisfactory experience on a higher quality set of headphones let alone the CrossFade M100's. A lot of attention has quite rightly been given to sound quality and performance with equal attention also given to build quality and style. Don’t get me wrong, the experience is not disappointing by any means, I just need to point out that the dual-diaphragm 50mm drivers inside the CrossFade M-100 Headphones are so much more capable than you may think."

Update (June 22-2013, 4:43pm EDT): I was contacted by Noctua about the TDP ratings... quoting from their email:
As for the question regarding the TDP rating of the original NH-D14, I'd like to stress that the cooler can *easily* handle any 130W CPU! Our D14 is renowned to be among the best performing heatsinks for overclocking on the market and and many users have pushed their CPUs well beyond 250W using this cooler.
Noctua apparently does not like including TDP values for their coolers because it varies heavily on the conditions (such as, of course, room and case temperature). It makes sense, of course, because then customers would go looking at reviews and see what overclocks were achieved with the system.
Yes, I know Computex is long over, but I missed something that I want to cover.
Noctua has been teasing active noise cancellation (ANC) for their CPU coolers for quite some time now; Tim published his brief thoughts, 13 months ago, on their press release leading up to Computex 2012. The prototype, this year, is a full unit rather than the fan from last year.
This design is a modified NH-D14 cooler with added technology from RotoSub AB to sample its own noise and destructively interfere. According to Noctua, this will be the first ANC cooling unit for a CPU. The plan, as their press release suggests, is to release a cooler with the model named "R-ANC" after its (R)otoSub (A)ctive (N)oise (C)ancellation (R-ANC) technology. To me, this seems like a confusing choice in name as it breaks away from their existing standard and limits choice in name for future models based on this technology. Personally, I would have preferred to see "NH-D14R" or "NH-D14ANC", but alas I am not a marketer.
Also, in the process of researching for this article, I have been unable to find a canonical TDP-rating for this device. I was not too surprised to have a difficult time finding it for this unreleased product, but TDP is even omitted from the established, albeit louder, default NH-D14. Some sources claim this cooler can support an Intel i7 Extreme processor, which typically requires a 130W thermal dissipation; other sources say you should be somewhat cautious with this cooler with CPUs >95W TDP; some even claim it is great for air-only overclocking. Rolling all of these sources together, assuming a kernel of truth in each, I would assume this cooler (and, by extension, its upcoming R-ANC variant) would be good for decent air-only overclocks until you reach the -E series.
But, grain of salt, have some.
No word of pricing, but Noctua believes they will have it available spring/summer of next year. For some reference, the default NH-D14 can be found for about $75-$100; expect the R-ANC to be slightly north of that.

Audio-Technica's ATH-ANC9 QuietPoint headphones are definitely priced for audiophiles, most casual listeners are not willing to spend ~$300 on headphones whether they have active noise cancellation or not. 40mm drivers and a frequency response range of 10 - 25,000Hz give a hint towards the audio quality and there are three different noise cancellation settings for those who might sometimes want to be able to hear environmental sounds. When [H]ard|OCP first looked at the headphones they were not sure as to how comfortable they would be after extended periods of time wearing them and were quite surprised that they were not bothered by extended usage at all. Audio quality was superb, though [H] does point out that this might not be the best gaming headset, for that use you might be better looking to a headset which provides surround sound. Those looking to enjoy audio without interruption from the outside world will like this product, if they are willing to pay the price.
"Noise-cancelling headphones are very popular with frequent travelers and those who live or work in noisy environments. Audio-Technica's new ATH-ANC9 QuietPoint headphones supply you with three modes of operation that have impressed us to say the least. Now you can get on with grinding in peace."

No matter how loud you have the ASUS Vulcan ANC headset you will never hear anyone around you complain thanks to the active noise cancellation feature. While it does mean you will occasionally need to feed the headset some batteries as well as keep them plugged into the 3.5mm audio out on your computer. However doing so will mean you can game in peace without worrying about background noise disturbing your concentration. At $120 they are not inexpensive, however Neoseeker found the sound quality more than acceptable and were even happier with the noise cancellation performance.
"As you may have already guessed, the ANC stands for Active Noise Cancelling. That's correct, the ASUS Vulcan ANC is the first active noise cancelling headphones made specifically for gamers. If you've got a loud computer, or a roommate that won't stop talking, simply put on your Vulcan ANC headset and turn the noise cancelling on! The removable mic adds versatility and does let the pro gamer headset come across as a headphone more geared toward audiophiles."

Enthusiast PC fan manufacturer Noctua has announced a partnership with RotoSub to produce fans with active noise cancellation technology. They two companies have already developed a prototype chassis fan that uses fan blade modulation and a series of stationary blades in addition to the moving fan blades to improve performance while keeping the noise down. The noise canceling fan prototype will be shown off at Computex 2012 in Taipei next month (booth J1312 in Exhibition Hall 1F).
In a recent press release, RotoSub and Noctua have announced a “strategic partnership” to develop and market a line of Noctua fans with a new noise cancellation technology from RotoSub. The technology in particular is called the RotoSub Acive Noice Control (R-ANC). It uses phase cancellation principles to cancel out the annoying hum (or whine in those smaller server fans that sound like jet engines) given off by the fans. The fans do this by slightly modifying how the blades spin using proprietary algorithms (hopefully they will release more information on exactly what is going on there), and by including physical features like the stationary set of fan blades behind the moving set of blades.
The prototype Noctua NF-F12 fan that will be on display at Computex 2012.
Mårten Oretorp, RotoSub CTO stated that the company is aiming to achieve 80% more airflow and 120% greater static pressure than the Noctua NF-F12 fan by incorporating the company’s ANC technology. Noctua is licensing the RotoSub technology, which is claimed to deliver better noise-per-performance ratios than can be accomplished by physical aerodynamic improvements alone.
Further, Noctua CEO Roland Mossig stated “it has always been our goal to push the boundaries of acoustic optimisation and this partnership will allow us to reinforce our technology leadership in the field of premium grade PC cooling equipment.”
RotoSub hasn’t detailed the algorithms but they do have hints of information on their page including a video demonstration of the fan and an animation that shows the “anti-sound” being generated by the fan itself to cancel out the annoying fan noises that it produces. The video can be seen below.
It is an interesting concept, and I hope that it works. While moving to watercooling has cut down on the number of fans I’m using in my desktop, it is still not anywhere near what I would call quiet. Stay tuned for more information once the prototype is shown off at Computex 2012.
