Performance alone is not enough to understand, also should be aware of the brand's history. Many old established manufacturers of the products have a headset "traditional" characteristics, the monster of the headphones can be divided into the European School, the American, Japanese faction, etc., each genre has its own characteristics .Europe to send more attention to sound headphone balance, focusing on the performance of the sound field, AKG, Sennheiser is the representative; the United States were paying more attention to the dynamic capabilities and high-frequency transient performance, beyerdynamic, Gaussian, Studio headphones, etc. on behalf of ;-Japanese usually focus on the performance of sound quality, more attention to musical instruments, voice texture and detail, a typical representative of a triangle, SONY and so on. In these factions, but also to free a "listening" to the Department headphones, this type of headphones depending on the professional use, the sound on a certain treatment, some of which can be used as models of headphones to enjoy HIFI headphones music, and some are not applicable. The conditions do not have the audition, I do not recommend you to consider headphones, because they are more "risky", of course, for experienced veterans, may not be a problem.
You have to understand the type of monster headphones, such as open, closed, semi-open and so on. Open headphones sound quality is usually better, but susceptible to the surrounding environment, closed headphones sound very good relatively rare, but there are very successful product.
Understanding of these indicators alone may not enough to make you determined to buy a monster headphones, because some things are very important. All have to consider what factors? Listen next time decomposition.
To know the monster of the future performance headphones, can not be immediately determined, there are other factors to consider. The back detail about one issue, that is the driving headphones problem.
Monster headphones have two important characteristics of targets, determines the stereo headset is easy to drive magic, is the sensitivity and impedance. Let me talk about sensitivity.
Sensitivity index for the monster of headphones is a very interesting target, it is the monster headphones for the sound quality is almost no contribution, but because it makes the existence of pairs of headphones for each of the driving source (amp) have put forward the corresponding output capacity requirements , does not meet the requirements of the driver can not be normal headphones loud rock, from this point that it is for sound effects and very large. That sensitivity, we have to understand something about the knowledge. Such as loudness, loudness curve, right, and weighting, people feel different loudness of the sound and so on.
Loudness is a method of measuring sound intensity, expressed in dB, the loudness of the knowledge can be found in many places, not repeat them here. Some data does fit in this column about: the general voice is about 60 ~ 70dB, a very loud cry can reach 100dB (screaming match?), The human ear can withstand the maximum short-term loudness at about 114dB, 120dB of sound make ear pain, 140dB of sound can make a permanent loss of hearing, more than 140dB sound syncope or even death may result. We listen to headphones to listen to music rather than testing the limits of the ear, so a headset can reach 110dB maximum sound pressure is sufficient. In fact, the average sound pressure can make us feel more than 90dB has been a very big sound.
Loudness curve: people of different frequencies of sound ability to feel is different, usually more sensitive to the intermediate frequency, for high and low sensitivity are relatively worse. For a sensitivity curve very flat systems, to ensure that various frequencies in the human ear to get the loudness are similar, then you need a different power output to match the human ear's loudness curve. In a different sound pressure, such as the human ear's loudness curve is a change, the stronger the sound pressure, loudness curve more flat, the human ear to different frequencies of sound feeling line.
Rights and interest over the issue have said many times before, simply click here, namely, the right is a line of human hearing characteristics of the statistical methods, the human ear count some of the more sensitive band, considered a little less insensitive, do not listen to not.
Impedance and sensitivity, just as with the sound quality has nothing to do but rather only the relevant parameters. Headphones can be said that a wide variety of anti-, the lowest three in Europe, the highest up to tens or even hundreds of K K Europe Europe (electrostatic headphones and piezoelectric ceramic headset). Our regular contact with the general dynamic headphones are 600 ohm impedance of the following. Complex impedance beats headphones so has its historical reasons. 600 professional headphones are generally in Europe, 300 Euro, 150 Euro, 120 Euro, 64 Euro these types, which is due to the reasons for the industry standard. General application of professional headset is a stage, radio, recording, etc., need to use a lot of these places for people to simultaneously monitor headphones, the most economical approach is to headphone series, parallel, and then to drive the power amplifier, in order to ensure that each of headphones In the series, in parallel to maintain the same sound pressure, it provides professional headphone impedance must be a 600 series in Europe and the combination of the results. For example, the series is 2 300 600 Euro in Europe. As for why the EU as a standard 600, or historical reasons, is not there something special about 600 European. There is not much to say.
Now the monster of these brand-name manufacturers of most headphones are professional manufacturers, in addition to civilian production also produces professional headphones headphones outside, and most of them started a professional product. So they designed civilian headphones when not consciously put some of the standard areas of expertise also incidentally to spend, and benefits of doing so is to save R & D investment and to ensure the continuity of product technology, allowing for relatively stable performance
