Наушники — Koss Porta Pro Mic/Remote

The Porta Pro Mic/Remote comes from Koss, the American company behind the SP3 Stereophone of 1958, and takes the Porta Pro, first introduced in 1984, and adds an in-line microphone and a one-touch remote to the cable. The additions target smartphone use, letting the listener answer and end calls or pause, play and skip tracks from the cord. The rest of the package follows the standard Porta Pro, including the collapsible frame and open-air cushions.

Key specs that matter

Its drivers are dynamic units whose voice coils use oxygen-free copper wire, and Koss quotes an extended frequency response of 15 to 25,000 Hz for the Porta Pro family. Impedance is 60 ohms and sensitivity 101 dB SPL at 1 kHz and 1 mW, the same figures Koss publishes for the standard Porta Pro. Connection is wired through a 3.5 mm plug. The lightweight open-air cushions allow hear-through, so outside sound is not blocked.

Engineering and use context

Koss describes the cable on this version as a rugged system with spring reinforced strain relief where the cord leaves the plug and the earpieces, a detail aimed at portable use where cables get bent and pulled. The headband collapses for protective storage, and a Comfort Zone setting on the temporal pads is meant to give a secure fit without excess pressure on the ears. A soft case is supplied in the box. Koss presents the model as a new version of the classic, listing the in-line microphone, the one-touch remote, the rugged cable and the spring reinforced strain relief as its new features, while the dynamic element and copper coils carry over unchanged. Warranty cover is the Koss Limited Lifetime Warranty, the same coverage it applies to its wired models. The Porta Pro line reached its 40th anniversary in 2024, and the Mic/Remote remains a cabled member of the family alongside the later Bluetooth model, which uses a dual steel headband to carry the audio signals.

Pairing

The impedance and sensitivity ratings place the Porta Pro Mic/Remote in the range of phones, tablets and laptops with a standard headphone output. The one-touch remote and microphone work with smartphones for calls and track control, so the headphone can serve as a headset for voice calls as well as for music playback on the move.

Alternatives

Within the same range, the Koss Porta Pro Limited Edition Rhythm Beige offers the same Porta Pro frame with an inline microphone, remote and attenuating volume control, plus a hard compact carrying case.
