Product Description

Style: HFI-780 | Product Packaging: Standard Packaging

The exclusive design of the closed-back Ultrasone HFI-780 is accentuated by the polar-silver color. The HFI-780 contains all Ultrasone technologies such as S-Logic Plus, ULE and safer hearing. The HFI-780 is developed from the studio sector and is distinguished by a frequency response that is specifically tuned for DVD and gaming. Sophisticated home theater and music enthusiasts are overwhelmed by the impressive sound that makes it appear as though you are listening to speakers placed meters away. Gamers are impressed by the exact sound reproduction, making the gaming world come alive. The low frequency ranges are raised in order to reach the highest possible synergies with DSP-Systems like Dolby Headphone and Yamaha Silent Cinema. Through S-Logic Natural Surround, the sound moves out of your head and into the room around you. Direction and distance are more easily perceived, giving the illusion of being at a live concert. With just a pair of Ultrasones and your favorite audio device, you can have genuine 3-dimensional aural enjoyment. The HFI-780 is equipped with thicker ear and headphone pads, and comes with a new velvet carrying bag.

TL;DR version =

PROS = Deep yet controlled bass; clear mids and highs; wide soundstage; "fun" to listen to; low-impedance (easy to drive); deep earcups don't cause ear fatigue; short cord (1m) for easy portability.

CONS = "Sparkly" treble might be too harsh for extended listening; clamping force might be too much for some people.


Now for the long version...

This review might be a bit lengthy, so bear with me. I take product reviews quite seriously, and as a reviewer myself, I try to make sure that I am as informative as possible, and to be completely familiar with an item before reviewing it. Anyway, today I'll be reviewing the HFI-780, and for the past year and a half, the HFI-780 has been one of the few things in my house that I use on a daily basis. When I'm in front of the computer, the HFI-780 is almost always on my head.

First off, I'm going to give a brief background of the headphones I've previously owned, and how I ended up with the HFI-780's. My very first set of headphones were the Sony MDR7506 Professional Large Diaphragm Headphone, which I bought over 5 years ago. They are still some of the best studio headphones on the market. Though personally, I found the sound signature to be a bit too flat/neutral for my liking. I wanted something that was fun. So then 3 years ago, I jumped ship to open-back headphones and bought myself a Sennheiser HD595 Dynamic High Grade Performance Premiere Headphones.

I have been on a mad search for good cans for my Ipod. To put things in perspective, I am a professional DJ, and quasi-audiophile. I have tried the Bose Triports ( way too basey, supressed hi's- a joke for $179); Grado SR80 (love them for sound- natural base and crystal sharp hi's; not comfortable for extended listening, but I kept them); Koss portapros (recommended by reviews, but too basey for my liking); Sennheiser Px100 (unimpressed) and Px200 (horrible, hollow sound w/ mimimal base (despite a 72 hr burn in); and these Ultrasone's (recommended by my brother- a professional musician). I first tried their ICans, but were uncomfortable because of it's inflexible,square shaped over-head plastic. They also broke within 3 days as well.

However, I was pleasantly surprised and happy with these headphones. They are incredibly comfortable, and light as a feather (despite being full-sized cans). The sound delivered is not as sharp as the Grado's, however are real natural sounding and pleasant on the ears. I don't know about the company's claim regarding surround sound, nor the decreased radiation to your ears ( I can only hope it's true). I just find them a pleasure from a comfort/sound perspective. I mostly listen to them, with the Grado's occasionally as a change of pace. I am very happy with this purchase. The cord is ridiculously long though (9 ft?). It definitley needs a wrap, which I have ordered and is on the way.

These headphones are a bargain. After countless positive reviews I took a chance on these and am generally impressed. I, like most others, had to purchase based on reviews since Ultrasone has no retailers in my area. The reviews were bang on.

My criteria were:
-closed cans (good isolation, low to negligible leakage, compact enough for travel).
-efficient (easy to drive, high sensitivity)
-FUN frequency response, with engaging sound.

I have a set of open air ATH-AD700's which have absolutely shining mids and detailed highs but are void of bass. They are about as portable as an agoraphobic. I listen to strings and vocals at home though so I needed something for electronic and dub out and about. For this purpose these are fantastic.

Real quickly I'll just say that both style and build quality are absolutely superb. Feels German: tight and clinically engineered. Both isolation and leakage are at least par for the course. Listening to these at moderate to high volume on a red-eye flight will be a non-issue. Some people have commented on comfort but for my average sized head and ears they are excellent. Not as soft on the skull as the ATH-M50 but not as hot either. Overall a non-issue once again. Cord length is a little long for a portable can, but that's by no means a deal-breaker.

Based on reviews I was expecting the following from these headphones:
-good, punchy, accurate bass response.
-life-like, sparkly highs.
-somewhat recessed mids.
-above average soundstage.
-overall a fun and engaging sound.

It was all true.

At first listen these were actually fairly disappointing: hollow and even tinish comes to mind.

Well I'm going to make this short but detailed and let me first start by saying I own Sennheiser HD650's , Sennhesier HD800's , Shure 1440's , Beyerdynamic DT 990 600 Ohm and just a plethora of other cans. These headphones are German designed and sonically aimed towards user's who prefer more detail than endless bass. That is not to say they don't have great bass because they do but I've heard much more bass heavy can's and these are an excellent balance that manage to keep bass important but not over saturate the sound so that it begins to interfere instead of enhance. Now I won't use lots of fancy Audiophile terms because if you are reading this review and interested in this can , it is not aimed at that group of users (although some of you are probably audiophiles so I'll thrown in a few terms here and there). Its aimed at the middle of the road user , someone who isn't going to spend $500 on a Woo tube amp and $600 on a DACmagic but someone that is willing to spend $80 on a portable all around headphone amp like the Fiio E6 or E7 to gain whatever enhancement they can at an affordable cost.

Now the best way to describe this headphone is detail , treble is well presented and full. Mid-range is up front and sounds clear , vocals come through well. Bass is as I described above and needless to say if you are a "bass head" then these will not be the cans you should go for (I would recommend Denon 2000's for that). And that's all I will say about its sound signature (except for music genre's). If you are reading this and wondering if a pair of Beats would be better than I can highly recommend you buy this over a pair of Beats.
