Indirect Sound to me is an annoying gimmick nothing more even if it allows higher volumes.

This is the best headphone I ever owned. It's pricey, but sound quality is the best.

These are my first pro pair of headphones, so this is my bench mark for the rest I will ever try. Pros *Clean sound and bass *Comfortably for hours of us with no issues and I am very picky about getting a headache easily. *Build quality seems good nothing feels like it will break easily. *Was not a big fan of EDM, until I tried these headphones. They really stand out for this genre. *Natural surround seems to work well for watching movies as well. Cons * you have to make sure you screw in cable to headphones well or sound will be in mono. *Bass could hit a little harder, but this can be tweaked. *Not much change from the 900's. Overall pleased and can't wait to listen to these for hours to come. Also shipping was fast!

Packaged w/ mobile & home detachable cables. Titanium Drivers - rigid, fast, thin/accurate. Includes case, extra pads. At retail among the best but at Adorama's price from a trusted/authorized source - best value anywhere. Unique in that they can produce the equal/greater volume with less pressure and 'other' technical negative side effects. If you setup an Atmos or DTS:X traditional speaker environment and you want to get surround via headphones for private listening - it is still 'the frontier'. I wasted hours trying to modify different cans meant for gaming or with wireless virtual surround - and they all disappointed. These 900's skip tech and batteries to take advantage of the biological design of our ears and naturally reflect the sound around your ears to simulate space and direction with any source - be it hi-res 2 channel audio or the algorithms good receivers or Pre-Pros like my Yamaha CX-A5100 has specifically to assist traditional headphones with movie sound tracks. With natural closed back and ample padding they lead very little for office/plane/public. They are efficient enough that my iPhone drives them great but you home or portable amp will permit them to shine and produce fuller separation and impact at even the lower volumes. As compared to my high end 7.4.2 (4 overhead and 2 SVS Subs) - I am literally picking up details and dialogue that I miss via even a huge investment on traditional sound. They enable me to connect with the daydream escape at night in movies without the guilt of bass resonating throughout the home. I have more than 10 sets of headphones and I don't have a pair under $1k that even come close to their performance with hi-res lossless music or UHD lossless movie soundtracks - highest recommendation possible.

Picked these up on sale. Great for the price. Honestly, they sound pretty good out of the box and, I'm guessing, will only sound better with time. Burn in time for these is 80 - 100 hours. Isolation is pretty good with a good seal from decent clamping force. The highs can be a bit fatiguing, but I'm hoping they tone down later. Mids are ok. The bass is AMAZING. Definitely recommended for bassheads. Soundstage and imaging are adequate for closed back cans. Still sounds like music is playing in your head. Build quality is pretty good for mostly plastic parts. It feels significant and all the moving joints seem pretty beefy. The velour ear pads are nice and my ears don't get sweaty like pleather pads. They fold down quite a bit but are still too bulky to fit in a coat pocket easily. I wear them around my neck with the drivers swiveled flat when I'm not wearing them on my head and they feel comfortable. Overall, I'm pretty happy with the purchase.

I really wanted to love these headphones. However,they were just to boomy. After about an hour the tops of my ears were uncomfortable. However, they are very well built and really a beautiful piece of euipment. No problems with Adorama, just too much bass for what I like.

Open back phones are generally considered the best sounding ones on the market. I had a specific use for closed back headphones though and Ultrasone came through with flying colors. I needed to be able to listen in the same room as my wife when she was concentrating on other things. I have two pairs of Ultrasone headphones - one model 750 and these 900's. Both deliver clear sound. However the 900's are significantly better for listening to Classical music because their bass response and smoothness is better than the 750's, and they bring an authority to the sound which the 750 does not have and I am happy to have them. For those looking for phones which won't disturb those around them these are wonderful headphones. Note about folding up these phones. are not huge but they are not tiny either. When folded they fit in a sizable zippered case that comes with the phones. They still will take space when packing luggage for a trip.

With these phones, I can listen to songs I thought were boring before, now the music just lights up. . They have a powerful bass but not at the expense of midrange tones. They will run just fine off an ipod. But, even better with a DAC amp. I use the TEAC and it is seamless with the lightening port. Comfortable fit, but I do find them little too big, I have to tilt Headband forward, works fine, but my head isn't that small, 7 1/8". I've recommended these to my friends.

Geared towards audio professionals and avid headphone users, the Pro Series 900i retains an incredible amount of detail even at extremely low frequencies as well as an immediate impact sound, warm, with loads of details, and fantastic performance. This is the first Ultrasone PRO headphones with the patented S-Logic PLUS technology.
Full artificial leather headband with padding for greater comfort
Enjoy unlimited sound performance with great detail, amazing imaging & fidelity, greatly reduced ear fatigue, and safety like no other headphone brand in the world. The closed-back Pro 900i headphones use the stiffest drivers available: Titanium-plated! These drivers offer the most exact and correct sound reproduction you can imagine. Using specifically developed velvet earpads, you will have fantastic comfort for extensive working hours, combined with a maximum of isolation.
With a 5-year limited transferrable warranty, this robust detailed audio professional and audiophile headphone utilizes the patented S-Logic Plus technology.
Great Sound - The Best Listening Experience
Natural Surround Sound is the only way to give you a listening experience the way you actually hear - by using the outer ear as the primary transfer mechanism. Instead of using centralized drivers that barrel audio directly down the ear canal, with S-Logic, audio reflects off the surface of the outer ear (which is used for 3-dimensional understanding of distance and direction). Audio "slides" into your head the way you naturally hear and allows you to hear musical nuances that you have never heard. Music sounds like the sweet spot of fine monitor speakers rather than headphones. Directions and distances can be heard and perceived - it's just like being in a live concert. For this new technology batteries or additional equipment is not required. S-Logic Plus A more vivid perception of voices and instruments S-Logic Plus is the newest advancement in the S-Logic Natural Surround Sound System.
S-Logic Plus profits directly from innovations developed for Ultrasone's flagship Edition range, the ultimate headphones for critical listening. This sophisticated technology combines precision dampening with micro-acoustic reinforcement, allowing driver, buffer-board, and spatial parameters to complement one another optimally. This results in maximum neutral sound impression with more vivid perception of voices and instruments.
Hours of Listening Without Your Ears Hurting
S-Logic also provides a reduction of sound pressure levels at the eardrum by up to 40%. This can reduce the risk of hearing damage while ensuring hours of fatigue-free listening.
The Pro 900i also feature ULE-technology (Ultra Low Emission) - MU Metal shielding. Headphone drivers produce low-frequency magnetic fields as they convert electrical signals into acoustical signals. With special MU Metal shielding (ULE-Ultra Low Emissions) this radiation is reduced by up to 98% compared to conventional headphones. These headphones are designed to isolate the music within the headphone as well as isolate the listener from outside sounds.
Designed with the professional in mind, these headphones feature gold-plated connectors to prevent corrosion, a foldable design, 2 easily detachable cables, 2 speed-switch removable ear pads and hard carrying-case for transportation and storage. Included inside the case are one coiled and one straight cable, and a spare set of speed-switch earpads, demo CD and Instructional manual.
