Understanding Earphone / Headphone Specifications
These relatively high-impedance headphones require more source voltage than a consumer device can typically provide. If you plug a pair of 250-ohm headphones into your mobile phone, you won’t hear much, even at max volume. They’ll usually require a standalone headphone amplifier, or a quality audio interface … See more Low-impedance headphones are a good match with the headphone outputs on battery-powered consumer devices like smartphones, tablets, and laptops. These headphones don’t require much voltage to drive them, so … See more You generally can’t go wrong with headphones in this middle ground — they can work with a wide range of equipment. Pair them with the headphone output on your DJ mixer, audio … See more Manufacturers report their headphones’ impedance as a single number — the “average” or nominal impedance. But that single snapshot … See more Back in the old days, way before laptops and iPhones were common, traditional studio and broadcast gear was relatively high-voltage.

Headphone Impedance and Sensitivity Explained - How-To Geek
WebJul 15, 2024 · Ohms are the units used to measure electrical resistance. The higher the number of ohms, the greater the resistance. Impedance, on the other hand, is a measure of how much a device impedes or slows … WebAug 31, 2024 · A headphone amp is a relatively low-powered amplifier that raises the low-voltage audio signal from a source device (be it a turntable, PC, or smartphone) to a sufficient level such that it can be ... WebOk. Ohms are the measurement of what is known as "impedance." This is analogous to resistance in DC circuitry (impedance refers to alternating current). Effectively, this boils down to how hard it is for the electrons to move through the component, whether it is a resistor or a headphone driver. お米10キロ 何号
