Product Description

From the Manufacturer

If you’re looking for a headphone with amazing clarity and transparency then this is the headphone for you. The titanium-plated driver is very light which makes for a incredibly clear and precise listening experience. And with S-Logic™ Natural Surround Sound and comfortable velour earpads, the PROline 750 will see you through many hours of listening.

The 40mm titanium driver gives accurate sound reproduction

Simply the Best

Great sound is all in the details. The PROline 750 from Ultrasone is the ultimate in craftsmanship, comfort and sonic purity. We hand-picked every component of these headphones to create a sound that is rich, enveloping and true to the recording. You’ll hear everything you never heard in your favorite music. And the velour earpads are so comfortable, you’ll forget you’re even wearing them.

S-Logic Natural Surround Sound

Ultrasone’s patented S-Logic natural surround sound system is a revolutionary advance in how we listen to headphones. S-Logic creates a natural three-dimensional sound field that gives the listener more depth to their music. S-Logic gives the listener a more lifelike listening experience and protects their hearing at the same time.

How Does S-Logic Work?

The outer ear, or pinnea, allows us to perceive distance and direction when we hear sounds in the real world. As sounds come into the ear, they bounce off the folds and peaks of our outer ear creating cues that help our brains figure out where the sound came from and how far away it is. Ultrasone headphones with patented S-Logic are the first headphones to utilize your entire ear, including the pinnea, in the listening experience. Through the use of decentralized driver positioning, S-Logic headphones aim the sound at the pinnea instead of directly down the ear canal. The sound does not go directly down you ear canal as with conventional headphones, but instead filters off the outer ear as you listen. By doing this, your perception of distance, depth and instrument placement are greatly enhanced. You can hear the mix exactly as the engineer heard it in the studio. Your ears are very sensitive, so you should take extra care of them especially when listening to headphones. An added benefit of S-Logic technology is an up to 40% (3-4dB) drop in SPL (sound pressure levels) for the same perceived volume. This means the Ultrasones put less pressure on your eardrum than any other headphones. Because of this, the risk of hearing damaged is greatly reduced and you can listen for longer without fatigue.

ULE Technology

ULE technology was systematically developed by Ultrasone for users who spend many hours in the headphones. All headphone drivers produce low-frequency magnetic fields. In response, Ultrasone developed a special MU metal shielding (ULE technology) to reduce the radiation by up to 98% compared to ordinary headphones.

5.0 out of 5 stars Ultrasone Proline 750 Headphones Are Magnificent In Every Way!, May 16, 2008

If you are looking for a pair of headphones that you can wear while you are running accompanied by the music coming from your MP3 player, the Ultrasone Proline 750 headphones are definitely not for you. However, if you really care about your music and sometimes listen to music attentively while doing nothing else, then the Ultrasone Proline 750 headphones are most definitely the right choice for you.
I have come to realize the opinions (especially among audio professionals) about such things as microphones, speaker systems and headphones vary tremendously. I think anyone who has actually heard the Ultrasone Proline 750 headphones and then writes a review expressing their supposed dislike for the sound of these headphones, belongs in one of these three categories:
1. They are lying for some reason such as they own, are employed by and/or have stock in a competitor headphone company;
2. There is something wrong with their hearing;
3. They are insane.
In my opinion, the Ultrasone Proline 750 headphones are absolutely the best, most accurate sounding headphones I've ever heard. You may be asking yourself which other headphones I'm using as comparison to the Proline 750's. The answer to that question is all of the best of the "top of the line" brands. I could name them but I think you understand the caliber of headphones to which I'm referring. While all of these companies manufacture excellent sounding headphones, none of them (I will repeat that) NONE OF THEM MANUFACTURE A HEADPHONE THAT SOUNDS AS GOOD AS THE ULTRASONE PROLINE 750 HEADPHONE, in my opinion.
The overall sound of the Ultrasone Proline 750 headphones is like none other you've heard before. The sound is more true to life. The sound is more like listening to an extremely high quality speaker system while one is positioned exactly in the perfect "sweet spot" of the speakers.
I will attempt to illustrate and exemplify the sound of the Ultrasone Proline 750 headphones by telling you that right now I'm listening to a recording by the late, great singer, Ella Fitzgerald using the Ultrasone Proline 750 headphones. As I listen and analyze the "sound stage" of this recording as it is playing through Proline 750's, Ella's voice is in the middle somewhat in front of my head at my forehead and going somewhat "into" the front of my head, the piano is playing just outside of my right ear, the tromones and saxes are outside of my head surrounding my left ear, the trumpets are outside of my head, above and to the front of my right ear, the bass is outside of my head mostly behind the back of my head and to the left, the string section (except for the cellos) is outside and up from my left ear, the cellos are mostly behind the back of my head, the drum is outside of my head and above my left ear and the guitar is outside of my head, above and to the back of my right ear.
Reading a description of what it's like listening to the Ultrasone Proline 750 headphones if you've never had this experience is probably something like reading about swimming if your only experience with water has been drinking it. You have to hear the beautiful sound of these headphones to truly appreciate them.
Like all high quality headphones, the Ultrasone Proline 750's require a "burn in" time to bring their sound to it's fullest potential. I am uncertain exactly how long is that "burn in" time. But, I will say that the more I listen to mine, the more I like their sound and I liked their sound a great deal the first time I used them direct from the box.
Since I mentioned "the box", I will tell you that judging from the way the Ultrasone Proline 750 headphones are packaged, one can discern that the Ultrasone company is one that truly cares about it's products and it's packaging. You will understand what I mean by this when you see the packaging.
Another way one can discern this caring by the Ultrasone company is from the construction of the headphones, themselves. Their construction is very sturdy and durable. Another reviewer indicated that because the Ultrasone Proline 750 headphones are made of plastic, they appear "cheap" in his opinion. First, I disagree generally that they appear "cheap" in any way. In my opinion, they appear as being quite professional. Second, I disagree that because they are made from plastic that (in and of itself) in some way causes them to be tawdry or "cheap" appearing or in physical actuality. Remember, there are different grades of plastic and the plastic utilized in the manufacture of the Ultrasone Proline 750 headphones appears to be a very rugged, dense plastic that will last for many years. The plastic in these headphones causes them to be light and comfortable to wear, certainly every bit as comfortable as any other headphone I've ever worn and indeed, probably more comfortable than any other headphone I've ever worn.
I give my highest recommendation to you regarding the Ultrasone Proline 750 headphones. All things considered, they are magnificent in every way.

5.0 out of 5 stars Plastic construction, October 21, 2009

Just wanted to quickly address the issue some have with the plastic construction of the 750s. I chose these over a pair of Denons because I'm currently deployed in Iraq and needed something I could fold away in a rucksack without destroying. My Ultrasones have been through quite a bit of abuse over the last 8 or so months and I've had no problem at all with durability (I threw out the fitted hardcase, no room for it). They show a little scuffing around the edges but are really very tough. Oh, yeah, they sound amazing too. I have them running to an ipod with a Bithead amp and everyone who tries them loves them.

I really like these headphones. Initially my Senheisers sounded better but as I listened to both headphones more over several weeks I came to like the Ultrasone headphones better. The sound did not seem as colored and the nuances more natural. I rarely listen to my Senheiser headphones and in fact have lent them to my brother and have not bothered asking for them back. I like these cans and think you will too over time.
