General Description
The foldable PXC 300 headphones with NoiseGard™ Advance active noise-canceling technology let you enjoy music in the most distracting environments. They reduce unwanted noise by up to 80% and the optimized circuit technology ensures reduced susceptibility to mobile phone interference. The PXC 300 is supplied complete with a protective soft case, batteries and aircraft audio adapters.
Features
- Closed, supra-aural mini headphones with switchable NoiseGard™ Advance active noise canceling technology
- Advanced Circuit Technology (ACT): reduced susceptibility to mobile phone interference
- The ultimate in portability; patented folding mechanism and protective case for storage and transportation
- Ultra-lightweight design with ergonomic headband, two-point suspension and soft high-quality ear cushions for improved passive attenuation and superb wearing comfort
- Duofol diaphragms with spiral embossing deliver transparent and lifelike audio reproduction with deep bass response
- Supplied with ¼ inch adapter and airline audio adapter (dual 1/8” jacks)
- Requires (2) AAA batteries for NoiseGard operation (included)
- 2-year warranty
- PXC300 versus PXC250: The PXC300 delivers deeper bass response, increased noise cancellation, thicker, softer earpads, a hard shell case and the ACT circuit (see above).

Glossary
| Cable length |
| The cable length is usually measured between the anti-kink sleeves of the cable (cable length without connectors). |
| Ear coupling |
| A distinction is made between headphones which are worn on the external ear (supra-aural) and those which surround the ear (circumaural). Open headphones have foam ear pads that rest on the ears or ring pads that surround the ears. Closed headphones, on the other hand, nearly always have circumaural ear pads. |
| Frequency response (headphones) |
| The frequency response of a pair of headphones is given within limits defined by the manufacturer. |
| Jack plug |
| A common audio connector in consumer electronics and music industry. Available in various diameters; in the hi-fi segment, 1/8" and ¼" are widely used. Poles range from one to four. (Examples: headphone jack or jack of an electric guitar). |
| Nominal impedance |
| See impedance. |
| Operating time (battery) |
| Indicates the operating time with a new, fully charged battery. |
| Sound pressure level (SPL) |
| Due to the impractical numerical values, the sound pressure is usually given as the logarithmic value of the sound pressure level according to the equation: dB SPL = 20 x log (po / 0.00002 Pa). The abbreviation SPL (sound pressure level) is added in order to make a clear distinction from other uses of dB. The reference sound pressure, which is at the same time the threshold of hearing, is then 0 dB SPL. The threshold of pain is 140 dB SPL. A difference in the sound pressure level of 1 dB is just about perceptible, while a doubling of the sound pressure corresponds to 6 dB and a doubling of the volume corresponds to a rise of 10 dB.

| Transducer principle |
| Two transducer principles have become established for the conversion of electric energy into mechanical energy: electrodynamic and electrostatic transducers, whereby the latter is only to be found in audiophile systems, due to their relatively high manufacturing costs. Electrodynamic transducers basically consist of a ring-shaped permanent magnet and an oscillation coil, which is fixed to the receiver diaphragm. When an audio-frequency alternating current is passed through the oscillation coil, it is caused to vibrate in accordance with the audio-frequency alternating current, thus causing the diaphragm to vibrate in the same way. |
