The ModRetro x Koss Porta Pro is a limited edition of the Koss Porta Pro, a wired on-ear headphone first introduced in 1984. Koss created it together with ModRetro, the retro gaming brand, in six exclusive colourways chosen to match the ModRetro Chromatic handheld game console - Bubblegum Pink, Leaf Green, Wave Blue, Inferno Orange, Midnight Gray and Volt Yellow. The edition was sold through ModRetro at USD 49, and the Koss listing now shows it as sold out.
Key specs that matter
Electrically the edition follows the standard Porta Pro. Koss rates the dynamic elements at 60 ohms, with a frequency response of 15 Hz to 25,000 Hz and an output of 101 dB SPL for 1 mW. A straight dual-entry cord of 1.2 m is used, with a standard 3.5 mm jack at the end, and it is fixed to the earpieces. As with the rest of the wired Koss catalogue, the headphone carries a Limited Lifetime Warranty.
Engineering and use context
The design keeps the folding construction that has defined the Porta Pro since the 1980s. The headband adjusts in length, adjustable temporal pads let the wearer change how the earpieces sit against the head, while foam cushions cover the earpieces. Koss points to the light weight and to the way the headphone collapses small enough to carry in a pocket. According to Koss, the partnership was built around colour, with the published specification, cord and warranty unchanged from the regular Porta Pro, which the company describes as one of its most popular headphones worldwide. Spare cushions in standard and oversized form are listed by Koss as Porta Pro accessories. ModRetro positions the six colours alongside the Chromatic console, which makes the edition a companion for portable gaming as much as for music. The wired design needs no battery or charging, and the headphone includes no microphone.
Pairing
The sensitivity and impedance ratings let the ModRetro edition plug straight into the headphone output of a handheld console, phone, laptop or portable player. The ModRetro Chromatic, the console the colours were designed for, is the obvious visual match. Sources without an analogue output need a USB-C headphone adapter, and a 6.3 mm adapter allows connection to the full-size socket of a home amplifier. For transport, Koss offers both a soft pouch and a rigid case made for the folded Porta Pro.
Alternatives
The standard Koss Porta Pro offers the same specification in regular colours at USD 49.99.
