Наушники — Koss CS100 USB

The CS100 USB is an open-backed over-ear headphone from Koss, built with a USB connector for direct digital connection to a computer. Koss has built decades of experience across both analogue and digital-connected headphone formats, and the CS100 USB represents the brand's straightforward entry point into USB-connected over-ear listening.

Position in line

It sits alongside the CS195 USB and CS200 USB in Koss's CS range, sharing the general open or vented acoustic design approach used across the family. This positioning within a range differentiated mainly by connector type and acoustic scheme suggests Koss builds this platform around a shared core with variants adapted for different connection preferences.

Key specs that matter

Rated response is 30 Hz to 16 kHz. Sensitivity is 91 dB per milliwatt into 32 ohms, an efficient design that should reach comfortable listening volume without difficulty. Connector is USB-A, drawing power and signal directly from a computer rather than a conventional analogue headphone jack.

Sound and use context

Expect the open, airy character typical of an open-backed design, with the USB connection handling digital-to-analogue conversion internally rather than relying on a computer's own onboard audio circuitry - this can be a genuine practical advantage on a computer with a mediocre built-in sound card, since the headphone's own conversion stage takes over that role entirely.

Pairing

The USB-A connector works directly with any computer offering a compatible USB port, requiring no separate headphone amplifier or external DAC since the conversion happens within the headphone's own cable or inline module.

Alternatives

The CS195 USB and CS200 USB sit alongside this model in Koss's CS range with different acoustic schemes, worth comparing directly on open versus vented design before choosing between these positioned Koss USB-connected headphones. Koss decades-long reputation for accessible, comfortable headphones extends across its whole catalogue, and buyers drawn to this specific USB model should find the broader Koss ownership experience generally reflects that long-established track record. Ear pad replacement, when eventually needed, is typically straightforward and affordable given how widely available Koss spare parts tend to be. A dealer visit remains the simplest way to compare this model against both the CS195 USB and CS200 USB.
