Our Verdict
The KSC75 like the Koss Porta Pros are not the most versatile headphones. They're flimsy and lacking in features. They also don't isolate much and leak due to their open design. However, they produce a decently balanced sound that lacks a little bass but should be good enough for most listeners. This makes them a decent option for critical listening but they might not be well-suited for other use cases.
- Above-average sound quality.
- Stable and portable design.
- Poor noise isolation, by design.
- Subpar build quality.
- Leaky at average volumes, by design.
The KSC75 Have a decently balanced sound. They have a good reproduction of Mid Range frequencies so instruments and vocals sound full and decently balanced throughout the mix. They lack a bit of Bass and their Treble Range is a bit inconsistent so they may sound overly sharp on some tracks. They have a relatively good Soundstage despite the small ear cups thanks to their open design which makes them a decent, budget option for neutral listening but they won't be the ideal headphone for fans of Bass.
Not ideal for commuting. They do not block a lot of ambient noise and won't perform well in loud environments.
Mediocre at best for sports. They're lightweight, compact and have a stable clip-on design. The open ear cups also allows you to monitor your environment. However their non-detachable cable may yank the headphones off your ears, they have no control scheme and they're also not as breathable or as comfortable as the Koss Porta Pro.
Subpar for office use. They leak at higher volumes and don't prevent the chatter of a lively office from seeping into your audio.
