Koss Porta Pro Wireless Review | 93 Data compared

The Koss Porta Pro Wireless 2.0 is a lightweight (80g) Bluetooth 5.2 on-ear headphone released for the 40th anniversary of the original 1984 classic. It retains the iconic retro aesthetic, collapsible design, and "comfortZone" clamping-pressure adjustment, but introduces a dual-steel headband that transmits audio between earcups, eliminating external neck cables. On the positive side, the review praises its impressive 20-hour battery life, excellent sub-bass extension, lively micro-dynamics, and an organic, highly detailed sound signature—especially in the upper treble—offering remarkable clarity for its €99.99 price point. Additionally, it comes packaged with a practical softshell transport case and a USB-C-to-3.5mm analog bypass cable. However, the headphones come with several notable drawbacks for modern users. They lack a companion app for personalization, do not feature Active Noise Cancellation (ANC), and provide minimal passive isolation against external surroundings. On the technical side, connectivity is restricted to the basic SBC and AAC audio codecs, entirely omitting high-resolution alternatives like aptX or LDAC. The build relies heavily on cheap plastic elements, the integrated control buttons feel less than premium, and the included charging cable is exceptionally...

The Koss Porta Pro Wireless 2.0 successfully updates a 40-year-old on-ear classic by cutting the cord while preserving its signature warm, bass-heavy sound profile. Weighing just 80 grams, these headphones retain the iconic, lightweight retro design featuring adjustable temple pads and flexible earcups for long-lasting comfort. Modern technical upgrades include Bluetooth 5.2 connectivity with support for SBC, AAC, and the high-res capable LC3 codec. They also boast an impressive battery life of over 20 hours and include a discrete three-button layout on the right earcup for easy playback control. Furthermore, a 1.20-meter USB-C to 3.5mm mini-jack cable is included, allowing users to switch seamlessly to a wired analog mode if the battery runs flat.

The Koss Porta Pro Wireless brings a contemporary Bluetooth 4.1 update to a classic open-back design originally introduced in 1984 during the Walkman era. Instead of rebuilding the chassis, Koss modernised the unit by connecting the two ear cups with a short cable that houses a microphone, a remote, and the Bluetooth components. Weighing a mere 70 grams, this ultra-lightweight on-ear headphone retains the original vintage aesthetics, temporal comfort pads, adjustable temple pressure, and the iconic collapsible rolling mechanism for high portability. In terms of performance, the review awards it a 3.5 out of 5-star rating in the "Upper Class" ("Oberklasse") tier, praising its reliable secure fit and its "good to very good" price-to-performance ratio at an approximate price point of 100 Euros. A major advantage highlighted in the review is the inclusion of aptX codec support, which delivers a highly dynamic wireless sound signature. The headphones skip the overly dominant bass common in contemporary models, opting instead for a well-balanced acoustic performance where the clear tonal focus is placed firmly on the mid-range. Furthermore, users get an impressive 12-hour...

The Koss Porta Pro Wireless modernizes a 1984 classic by adding Bluetooth connectivity via aptX, while preserving its iconic, ultra-lightweight 77-gram steel-band design. Priced at €155, the headphones offer a comfortable, secure fit with a step-free adjustable headband that accommodates various head sizes for hours of fatigue-free listening. Sonically, it delivers a warm, dry soundstage characterized by punchy, distortion-free bass, a highlighted midrange that renders vocals naturally, and slightly rolled-off highs that eliminate any harshness. Key pros include its impressive 12-hour battery life, robust inline physical controls for volume and track skipping, and excellent spatial sound separation. However, the review highlights several notable cons, most significantly the lack of Apple AAC codec support and a design that feels less premium on first look. Additionally, its legacy open-back design suffers from significant sound leakage to the surrounding environment, and it relies on an outdated Micro-USB charging port instead of USB-C. Overall, it earned a strong rating of 5.3 out of 6 points.

The Koss Porta Pro Wireless 2.0 is a lightweight, 80-gram on-ear headphone that maintains the brand's iconic 1984 retro design while adding modern Bluetooth connectivity and a detachable cable option. Priced at a budget-friendly €100, the build combines metal, plastic, and foam in a highly robust structure that allows the earcups to fold inward for easy storage in its compact travel case. On the positive side, reviewers praise its spacious, transparent, and naturally warm sound signature, excellent voice clarity during phone calls, and a decent 20-hour battery life. It also features a dual-switch adjustment system to change the headband pressure. However, the headphones come with several drawbacks, most notably the omission of modern features like Active Noise Cancelling (ANC) or a companion smartphone app. While comfortable for the first few hours of listening, the on-ear design eventually causes noticeable and uncomfortable pressure directly on the ear cartilage. Additionally, bass enthusiasts will likely find the low-end performance disappointing, as the bass lacks deep extension into lower frequencies despite remaining punchy. Ultimately earning a "Good" overall rating, it remains a solid, affordable...

The Koss Porta Pro Wireless 2.0 is an open, on-ear retro-styled headphone priced at €99.99, serving as the legitimate wireless successor to the iconic 1984 original. Weighing just 80 grams, it features Bluetooth 5.2 connectivity with AAC and SBC codec support, a built-in microphone for calls, and an integrated battery delivering between 14 to 20 hours of runtime. Sound-wise, the reviewer highly praises the headphones for successfully preserving the legendary, natural, and wide soundstage of the original wired model, enhanced by a surprisingly tight and prominent bass response. Overall, it earned a strong 4.5 out of 5 stars and an absolute buying recommendation. The review highlights several key advantages, including its lightweight build, excellent long-term wearing comfort, mature Bluetooth functionality, and a highly transparent audio profile that offers great value for money. However, it is not without flaws. The primary complaint is its revised headband design; unlike its predecessors, which could be easily adjusted while sitting on the head, the new double-band geometry makes head-size adjustments somewhat stiff and stubborn, requiring the user to pre-adjust them before putting them on....

The Koss Porta Pro Wireless 2.0 is a modernized, Bluetooth 5.2 version of the iconic 40-year-old headphone classic, retailing for approximately €100. Maintaining its signature retro aesthetics and ultra-lightweight 80-gram design, the headphones retain the highly praised "Comfort Zone" adjustable headband and a folding mechanism that shrinks them down to the size of an orange. In terms of audio performance, it delivers a highly competitive, warm, and audiophile-grade sound profile characterized by a powerful, punchy bass and detailed mid-high frequencies. Notably, it introduces an analog bypass via an included USB-C to 3.5mm jack cable, allowing users to continue listening even when the internal battery is completely drained. However, the review highlights several modern trade-offs for this nostalgic package. On the positive side (pros), the headphones are surprisingly robust, highly compact, exceptionally comfortable for large heads, and deliver excellent sound quality for their price point. On the negative side (cons), the device lacks any smart features, including a dedicated companion app, active noise canceling (ANC), or equalizer adjustments. Furthermore, its battery life—while improved to over 20 hours—is considered relatively short by...
