Bose never releases them, but I have got a pair of QC2 headphones, and I must say it is pretty much balanced all around the sound spectrum. I hear full deep bass and clear sound with detail among the highs.
Any wave can be cancelled by a wave of the same frequency and magnitude, but with the opposite period. These anti-waves completely cancel out the original wave. Noise-cancelling technology in newer headphones uses this same principle with sound waves, but all waves have similar principles.
Noise cancellation headphones work by blocking high-frequency sound waves and erasing lower-frequency sound waves. This can occur due to their ability to mimic incoming noise in order to produce their own sound waves.
A ferrite suppression sleeve is a cylinder of ferrite with a hole in the middle through which a wire or cable is passed. This device adds a "chunk" of inductance around the wire, and this results in the suppression of higher frequency signals. Power supply cables and other conductors that carry low frequency alternating current may have one of these sleeves installed. They are used to suppress high frequency interference and keep it from getting into or out of the equipment where they are installed. Use the link below to see some images and get a feel for what these are so you'll be able to spot them in the future.
a frequency counterIt all depends on what you're measuring the frequency of. From what I have found, you need either a frequency counter, or if it's sound, a CRO(cathode ray oscilloscope), but a high quality one is extremely expensive, or if you have an iPod touch/iPhone and headphones with a mic, just get an app for it.Gladometer
The standard frequencies are: * Dual-channel for two car audio sources * Carrier frequency: *: A source: 2.8MHz (right) and 2.3MHz (left) *: B source: 3.8MHz (right) and 3.2MHz (left)
No, the Beats heaphones are designed for low frequency sounds. I would be more concerned with your hearing than the drivers in the headphones.
Honda Odyssey headphones for models made after the year 2003 work using Infrared (IR) technology. A beam of IR light, like the one that is used in your TV remote, is used to transmit audio signals. This has advantages over Radio Frequency (RF) headphones in sound quality and battery life. I lots my Honda Oddyssey headphones and ended up having to find replacements from http://www.audiovideo2go.com which is the only reason I discovered the difference between IR and RF headphones.
As low as possible to as high as possible, but don't go just by frequency response. Anything by Sony or sennheiser are normally good. A good unknown brand I found were Urbanz. Decent frequency response is generally anything from 20Hz and lower to 25KHz and higher. For example, 10Hz to 28kHz is decent. Some professional headphones (such as professional sennheisers) boast 3Hz to 50kHz, but unless you are a music producer this is rarely necessary. Hope this has helped :)
RS120 926 MHz Wireless RF Headphones:The Sennheiser RS-120 includes one set of HDR 120 headphones and a TR 120 transmitter, but additional headphones are available for purchase. The transmitter can transmit to any number of headphones, as long as they are all set to the same frequency. While the transmitter has an RCA-type input, it includes two adapters that allow it to use 1/8″ or 1/4″ connections as well. This allows it to accept input from any number of sources: computers, TVs, MP3 players, stereo systems, and more. With so many possibilities, you will find uses you had never thought of.
When wireless headphones are referred to as "analog", it means that the audio signal is directly frequency modulated (FM) on the wireless carrier rather than being digitally encoded. One benefit of analog transmission is that there is no noticeable delay in the sound path. Many digital headphones compress the signal at the transmitter and decompress at the headphones. This processing takes time. Digital headphones can be horrible for use while playing guitar for example because you can play a note and not hear it for 100 milliseconds or more. Using these for television can cause lip syncing problems. However, for just listening to music, they're fine. Analog headphones audio can be accompanied by distracting hiss if signal strength is weak or if other RF devices interfere with transmission. Sometimes placement of the transmitter or headphones is critical in eliminating this noise. Digital headphones can also have signal quality issues, but they tend to simply stop working rather than introduce hiss.
It needs more than an electromagnet. You have an electromagnet with an iron diaphragm in the magnetic field. When the audio current from the amp flows in the electromagnet, the diaphragm moves at the same frequency, making the sound that you hear.
The ration of a frequency to its total frequency is called relative frequency.
Relative frequency is a method of calculating the frequency of an event. Percentage frequency is a way of presenting the frequency of an event.
Wireless headphone work by transmitting signals from across two bluetooth or high frequency capaple devices. Generally the two devices consist of the base, which sends the signals, and the reciever (ear piece), which recieves the signals.

Studio goes over the ear and solo's are an on ear head phone. If I were you get the studio, they cost much more, cover the ear, but the solo headphones sound the same as skullcandy hesh, and cost 130$ hesh cost 50$. the studio look better sound better and you can return them if you don't like them. If you get the solos you should be ashamed because the skullcandy hesh sound identical. The studio versions are meant to be worn comfortably longer and offer a wider and more clearer range of music frequency.

Transmit RF frequency subtract to the Receive frequency
frequency meter is used to measure the frequency of unknown frequency signal.
If you subtract from the carrier frequency the frequency of the tone that modulates it, then filter out the carrier frequency, then you have a lower sideband frequency. If you add to the carrier frequency, filter out the carrier, then you have an upper sideband frequency.
The natural frequency of the spring refers to its frequency when hit or struck. Its lowest frequency is called fundamental frequency. For a spring, the 1st mode of natural frequency is fundamental frequency.
Given a frequency table,the first cumulative frequency is the same as the first frequency;the second cumulative frequency is the sum of the first cumulative frequency and the second [ordinary] frequency;the third cumulative frequency is the sum of the second cumulative frequency and the third [ordinary] frequency;and so on.An alternative definition is that the cumulative frequency for any value is the sum of all the frequencies less than or equal to that value.
frequency density = frequency/group width
Uplink frequency is a frequency that goes from the ground to the satellite. Downlink frequency goes from the satellite to the ground.
