What is the point of having 46khz? Isn't the human ear only supposed to be able to hear up to around 20khz?

And indeed a lot of headphones roll off sharply at around 20khz for this reason - why bother to reproduce sound at this range accurately or at all? Some will argue that the sounds at >20khz have subharmonics that do reach below 20khz, and so you need the higher frequencies. Others claim to be able to hear beyond 20khz or to be very sensitive to the higher frequencies. You can also argue that it surely doesn't hurt to reproduce beyond the normal human hearing range, and that it might be a sign of the engineering excellence of the system as a whole. Me, I don't take sides, but tend towards the latter point of view: Probably not needed, but won't hurt.

The gestalt of the human experience in real life transcends mere numbers. See for yourself, judge for yourself. Remember CD's at first? Perfect music forever? You need to always consider the whole in person with an open mind. We apprehend more than we comprehend. Good luck!

These do not use electronic noise cancelling, so the attenuation is all mechanical, and very dependent on the user's selection and fit of the earpiece "sleeve" in each ear. Moreover, the amount of attenuation varies by frequency (the loudness of bass, midrange, and treble components in the ambient noise), and by duration of amplitude (a gunshot peak versus constant jet engine noise). Best way to determine if "enough" noise is blocked is to try them, rather than rely on numerical units such as dB (which can be weighted flat on the "A" scale, to a hybrid "B" scale now seldom used, to the "C" scale that approximates the frequency response of the human ear.)

I have a similar age-related hearing problem which makes higher frequency sounds more difficult to hear. I use the Sennheiser 555s to listen to TV programming and find them quite satisfactory for this purpose. One caveat though is that I watch TV programs on my computer and also use a graphic equalizer. I think using an equalizer is the key here as it allows one to boost the high and mid frequencies and decrease the lower frequencies, making it easier to understand spoken voice. You wouldn't need to use a computer to gain the benefit of a graphic equalizer. You could set this up just as well with a stereo system hooked up to the TV.

I don't know how good your hearing is.When it comes near my ear i can hear a monotome humming sound. Then i know it is working. Otherwise i don't hear it, when further away.

They would! If I'm listening to music in the 20i, I know I can hear nothing else.On the other hand if someone yelled for help, you probably won't hear them either. I figure the airplane is okay to use them. The sound is terrific.

It sounds clear and the volume is average at best. If you are hearing impaired, you should look elsewhere. Hope that helps.

During normal non-gaming use, I barely know it is on. When I play a simple online game (Runescape) it really revs up and gets quite loud for me. Sometimes I would rather not play then to have the noise. But then again, I've been told my ears are quite sensitive.

its not that loud, altho u can still hear small amount of sounds from 2-3 feet away. it also depends what audio source ure using. [pc] (i test it by covering both of the ear piece and stretch my arms away from my ears)

Although it probably depends on the helmet, I can get to controls with the 2 helmets I own. I prefer the controls near my ears as they are with my old motorola headset but for $12 I can live with this :)Regarding complaints about sound quality, I was able to improve this significantly by using better fitting earbud covers than those supplied which we're quite small. Again, what do you expect for $12??

I use this amplifier for voice-over work specifically because it does not enhance any frequency ranges. Most headphones hype either the low mids or the lows. Also, you probably can set EQ in the TV to enhance certain frequencies.

For music it works, but your receiver needs to be at a certain volume, and there needs to be a certain amount of bass in the recording. It works out ok because the times I have my volume lower than %40 I usually am looking for a quiet relaxed sound without the booming bass. For example when it's late at night and I don't want to wake everyone thats already asleep.

Nope; but I'm 37, so a lot of my hearing at very high frequencies is gone. If you're in your teens/twenties there may be a sound that's audible to you, but not me (or the people who designed and tested it). If that's the case, congratulations on your lame superpower and get off my lawn.

Hi Alfred - MacBob's response is pretty much spot on. 30b is pretty much silent, your going to have a terrible time trying to locate somewhere with a reading below this level unless you are in a sound studio in which case you should probably buy a much advanced device. Anything less usually cannot be heard by the human ear very well. The cost to make a device to measure below this level would raise the price considerably. There are some out there that can read lower but you will certainly pay much more for these units.You should expect a normal "silent" room to come in at about 35-50 dba which is quite quiet.Sincerely,BAFX Products Support Hi Alfred - MacBob's response is pretty much spot on. 30b is pretty much silent, your going to have a terrible time trying to locate somewhere with a reading below this level unless you are in a sound studio in which case you should probably buy a much advanced device.

Two reasons; One, the RS-180 has ALC instead of "Surround". ALC is Auto Level Control. It makes quiet things louder and loud things quieter to even out the volume. Very nice when you have a hearing problem or you want to keep the volume at a minimum for whatever reason. Such as sensitive ears or wearing these headphone in bed next to a sleeping person. Two the 170's don't really have surround. They imitate surround sound by delaying certain sound frequencies and other subtle adjustments. It's called Psychoacoustics, look it up on wikipedia for a good explanation. It's the same thing the Bose Wave Radio does, listen to one next time you're strolling through target. It's a very different sound. Some people, like me, intensely dislike the manipulated sound that comes from psychoacoustics. So the 170s aren't a good fit for people like me. On the other hand lots of people (most?) really love that sound. There is nothing wrong with psychoacoustics, it's a great thing and for most people it's very enjoyable.

I personally hate the isolation of standard in-ears, so because you can still hear those around you and don't get the "isolation" feeling that standard in ears provide, they would in theory be great for this...Unfortunately the sound they provide is all treble. There is almost no bass response, so most instruments will sound thin and tinny. No serious musician will want to hear his or herself sounding like that. The concept is amazing and they are incredibly light weight and comfortable, but the price is far too high for the sound quality. If they ever improve the frequency response, they will be a fantastic product.

I believe that it only outputs 60Hz refresh rate which is more than the human eye can pickup, so you don't really need more than that.

Idk but when around a lot of ppl and turn them up u can't hear them. Just having them on without music, outside noise is very low.
