How many impedance does this premier headphone have? and how about it's sensitivity?

sorry my friend, i have no idea about those items. i can only answer you, that it is a marvellous headphone, who sings .you can find a review in an english magazine called "hifi +" a 2013's number. i just don't like the ear plugs who are not very confortable.best regardsi use it with my iphone or i pad plus a fiio mc kinley

i don't know. however, number spec is as good as your ears can tell. i have heard many headphones one of them is Stax. all I can tell you is that for the money, it is a very good sounding little earphone. hope this helps. :)

16 ohms impedance. As for it's sensitivity, it is more sensitive than my Klipsch earspeakers. So I can "lower" the volume settings on my mp3 player using the Final Audio Adagio III. If you do purchase them, do not go by the initial listening. I was disappointed because they sounded no better nor worse that the Klipsch I already had. But as they broke in, I can not go back to the Klipsch. It produces powerful deep real bass, where you can almost feel it and certainly can distinguish between the bass notes. The mid range is wonderful and the highs, all present with a delicate touch. Depending on how your ears are shaped will really determine the sound you get in your ears. But I love these and am happy to have them. They come highly rated in the audio press too.

Well it depends on what type of music that you listen to. If you are heavy-bass dance music that kind of guy. This headphone probably will not reach your satisfaction. But i can assure you clarity of this headphone is top-class.

If the sensitivity is above ~86 or so you should be OK. I am driving a pair of Sentry 100A which have a sensitivity of 92db. They make plenty of sound and sound quite good even without a good preamp (e.g. a smartphone input).

I'm Dj and I use the Sennheiser PX450 in the disco, and this headphone can drown out some 80% of external noise. I liked the noise-canceling it. In my opinion, the bass is weak, but this problem is offset by the noise-canceling.

Numerically, the FQ is 10-25,000 Hz.If you would like to see a graph that charts the headphone's FQ performance and compare it to other headphones, I refer you to headphone.com (http://www.headphone.com/headphones/koss-pro-dj-100.php). You will notice that the headphone has a significant drop in the 5k region.If you want my subjective impressions, I think the headphone is very balanced and "flat." I read a lot of people who claim that the bass response is lacking, but in my opinion, it is sufficiently present and natural. Personally, I think the 5k dip is more of an issue on some tracks. The frequency response in the higher regions is quite unstable.

Most headphones used with portable electronics are low impedance, around 32 ohms. The lower ohms make it easier for the amp to drive them. Headphones range in impedance from 16 ohms to 600 ohms. There can be some significant advantages to higher impedance headphones. A higher impedance allows for more turns of wire to be used in the voice coil of the driver. This can result in a better "motor system" with fewer compromises resulting in better overall sound. Higher impedance headphones also require less current to drive and that typically reduces distortion in multiple ways. The amplifiers driving headphone nearly always produce lower distortion into higher impedances. The difference between 24 ohm and 32 ohm is quite negligible. The "24 ohm" is somewhat of an odd number in terms of ohms as typically, you will find 16 and then 32. You shouldn't have any problem using the 24 ohm but you will likely get a better response from headphones rated at higher ohms. You don't state the type of headphones. If you have headphones designed for portable consumer use that have an impedance of 80 ohms or less, it's very likely the manufacture designed them to be driven directly from a typical device like an iPod. Using an amp or DAC with such headphones usually won't improve their sound much, and might even make them sound worse or create other problems like excess noise and channel balance issues. This is especially true if your headphones already get loud enough for your tastes. Generally, 16 - 32 ohm headphones with a sensitivity rating of at least 100 dB/mW do not need an amplifier.

Robert, re: Use w/head amp and handling + impedance? - Yes, I use the Pure I-20 DAC ( $100; from an Onkyo receiver ), into a $50 Rolls HA43 Pro amplifier, and my source is a 4th gen, 8gb ipod. Nothing fancy but it works fine. Now as far as the impedence, yes, I use 50mm Mono 8323's mainly with this setup and it easily pushes them. I have used bigger Shure and AKG headphones and this setup has pushed them fine also.BB

I dunno, 1mW, I only know that the sounds are the best I ever heard, even better then my Bose headphones. A con is that it is a kind of open headphone, which is good for the quality but bad for your surroundings. The best to listen at home by yourself to different kinds of music, but one of the worst to listen to on a train or bus, you will make the other people around you very angry LOL

higher or not the default headphone is the front plug just because you have a easy access button for switch between your speaker and headphone. If not technically the same output watt. The knob button is the master volume for both of them. I have a 128ohms headphone and at 25% is too loud for me.

I am not familiar with your headphones but I have found that amplifier makes a difference but might denned on sensitivity of your headphones. I use it with my iphone an my cowen mp3player

This appears to be microphone level or at best line level inputs and outputs. Sadly the description doesn't say what the levels or impedances are, but the example in the text implies this. Headphones & speakers are very low impedance and much higher power (wattage) than mic or line levels, so I would be very surprised if you could heard anything, let along acceptable volume and tone, if you directly connect headphones, which would also require at least a mono/stereo adapter.

There is some specs but they don't differ from what amazon has listed. These headphones are great! They cancel out background noise so you can be immersed in your music. They do leak a little bit of sound but not much to bother others unless you are listening to your music really loud. They are great for gaming as well! Direction of footsteps can be heard.

This is the best information I can provide: Type Headphones - Binaural, Headphones Form Factor - Full size, Headphones Technology - Dynamic, Connectivity Technology - Wired, Sound Output Mode - Stereo, Frequency Response: 10 - 23000 Hz, Sensitivity - 106 dB, Impedance - 32 Ohm, Diaphragm - 1.6 in, Magnet Material - Neodymium. Hope this provides some help.

I have a samsung tablet and a pair of beyerdynamic dt770s which run at 250ohms. The amp is needed to drive them and it more than does the job. Totally different with them at such a cheap price. Actual sound is comparable to systems costing 5 to 10 times as much.

The Beyerdynamic web site shows 250 ohm. See the linked spec sheet. All I know is these cans are hard to drive. I finally broke down and bought a Beyerdynamic A1 amp to push these. Its not the volume that is the problem; its power needed to push these cans to accurate resolution. These are much more finicky than my AKGs or Sennheiser headphones.http://north-america.beyerdynamic.com/shop/media//datenblaetter/DAT_T90_EN.pdf

if you are looking for plane use i would not suggest this headphone as the isolation is low. you will be better off getting a close Can design or a active noise cancellation set. If you use it on a quite place, then this headphone sound wonderful. As for Ohm rating, what do you use to power the headphone? if you are using direct from you HP, MP3 player or direct from the airplane jack, you should buy the 32 OHM version. else you can try the 600 OHM if you have an amp

I only use headphones with it, not earbuds. I suppose out in public, earbuds would be less conspicuous. Why low? "a high impedance means a much clearer set of earbuds. You want to buy a pair of headphones with the highest impedance you can afford" http://ear-buds.org/what-do-the-specs-on-earbuds-mean/
