Higher impedance headphones are more tolerant of amplifier limitations, but produce less volume for a given output level. Historically, many headphones had relatively high impedance, often over 500 ohms so they could operate well with high-impedance tube amplifiers. In contrast, modern transistor amplifiers can have very low output impedance ...
For example, a 32 Ω headphone driven by a headphone amp with a <1 Ω output impedance would have a damping factor of >32, whereas the same headphone driven with an iPod touch 3G (7 Ω output impedance) [5] would have a damping factor of just 4.6. If the 120 ohms recommendation is applied, the damping factor would be an unacceptably low 0.26 ...
The impedance of a line input is typically around 10 kΩ. When driven by a line output's usual low impedance of 100 to 600 ohms, this forms a "bridging" connection in which most of the voltage generated by the source (the output) is dropped across the load (the input), and minimal current flows due to the load's relatively high impedance.
In analog circuits a high impedance node is one that does not have any low impedance paths to any other nodes in the frequency range being considered.Since the terms low and high depend on context to some extent, it is possible in principle for some high impedance nodes to be described as low impedance in one context, and high impedance in another; so the node (perhaps a signal source or ...
In 2019, Bose released the Noise Cancelling Headphones 700, also known as the NCH 700, a new high-end product positioned above the QC 35. [13] [14]The headphones have a stainless steel band and are controlled using a mix of buttons and touch-sensitive areas on the cups.
A high damping factor (which requires low output impedance at the amplifier output) very rapidly damps unwanted cone movements induced by the mechanical resonance of the speaker, acting as the equivalent of a "brake" on the voice coil motion (just as a short circuit across the terminals of a rotary electrical generator will make it very hard to ...
Standard headphones used in telephone work had a low impedance, often 75 Ω, and required more current than a crystal radio could supply. Therefore, the type used with crystal set radios (and other sensitive equipment) was wound with more turns of finer wire giving it a high impedance of 2000–8000 Ω. [106] [107] [108]
The NAIT 5i (italic 'i') has an additional 3.5mm jack for portable devices on the front panel, reviewers noted sonic improvements "from the first track"; it is demonstrably better at handling higher sound pressure levels than the '5i'. [16] NAIT XS: [Note 4] Reviewers have described the XS as a "SUPERNAIT in the slimmer casework of the Series S".
