Its robustness in addition to the Natural Surround Sound System makes the HFI-550 one of the most demanded headphones in the consumer sector. Customers appreciate its dynamic and power spectrum.With its particularly efficient 50 mm Mylar-electro acoustical transducer these headphones produce an impressive sound pressure even with a high environmental sound intensity. Furthermore it is made for high power input.Due to customer enquiries and requests, Ultrasone implemented an additional function which enables you to fold back and up the individual earpiece without removing these headphones from your head in order to be connected immediately with the “outside world” again. Because of this folding mechanism, these headphones can be compactly stored and easily transported in a suitcase. Thanks to its closed construction, external noise is suppressed. You can thereby concentrate exclusively on the transferred music or spoken language you are listening to.Through the S-Logic Natural Surround Sound the usual headphone sound will be moved out of the head in the room around you. The sound is no longer locked in, but appears broad and detached. Directions and distances can be heard and perceived - it’s just like being in a live concert.For this new technology additional equipment is not required. A pair of Ultrasone headphones plus a simple CD player and you will be ready for the 3-dimensional music enjoyment!In addition, the HFI-550 is easy on the ears: The S-Logic Natural Surround Sound System allows an up to 40% lower dB output (3-4 dB) for the same loudness sensation, thereby the risk of hearing defects may be reduced enormously.Like all Ultrasone products, the HFI-550 has a strongly reduced radiation. The standard version LE (= low emission) offers a reduction of approx. 50% in comparison with ordinary headphones. It is certified and recommended by Technical Surveillance Organizations and Consumer Advice Centers with certified lowest magnetic field emissions.
Customer Review: Impressive headphone
I got one as a Christmas gift and I’m really impressed with it. The S-Logic is more than just one of those fancy “techy” names, it really makes you feel a deep and superb sound definition.

I enjoy pretty much all types of music, from classical to heavy metal, from jazz to acoustic solo guitar. It passed the test in all sorts of music. I use it with either my iPod or listening to music on my computer.

Pros: the sound quality is astounding. I’m a musician in my spare time and this headphone allows to me hear everything in such a detailed level that I have the impression that I’m listening to songs I’ve never heard before. The bass is punchy, the trebles are bright. Isolation from external noise is great. The volume is also great.

Cons: I wish it was a little lighter and smaller. The cord is too long (3 meters), and sometimes it’s a little tight on the ears, but I got used to it.
Customer Review: This is one good piece of equipment!
I originally purchased these headphones from a company I work at (which I believe I’m not allowed to name on this site!), and I bought them to replace an old work out & broken pair of $20 Sony headphones I’ve been using over the last 2 years.

These sound great, and are able to reproduce near 10Hz - which is about as low as the 12″ sub-woofers in my car go! The Ultrasone HFI550’s also have great high-range - and seriously… EVERYTHING sounds 100% better then the cheap pair I was using before.

That’s about it! These sound great, are durable as heck, have a 3-meter cord and gold-plated 1/4″ & 1/8″ plugs, S-Logic surround sound (awesome, btw if you’ve never head surround in a pair of headphones before!) and have a 2-year warranty! What more can you ask for!?

The only down side I’ve discovered is that they’re kind of heavy compared to other studio phones - but on the contrary, they seal well and block out MOST outside noise (my co-workers have to tap my shoulder to get my attention when wearing them!!!)

I hope my review helps someone out! I didn’t once regret spending the cash for such a quality piece of audio equipment! “BUY NOW”

The ULTRASONE DJ1 PRO headphones are geared for professional DJ applications where their sealed-back construction will help to attenuate distracting ambient noise. The accentuated upper frequencies of the DJ1 Pro may prove especially beneficial to DJs seeking to keep on top of of hi-hat & cymbal cues or track their scratch/mixing synchronicity while working multiple turntables or mixing sources. Their full bass response helps to approximate the deep bass of dance music or hip-hop production styles. The mid-range response is perhaps just slightly recessed which gives the overall sound a hint of discontinuity that serves to emphasize the lower and upper parts of the sound spectrum. The seal from external noise is good, making these excellent headphones and a good choice for club DJs. “BUY NOW”
