If you want a clear retro look and in-line call controls for vlogging, choose Koss CL/20i; if you need a collapsible design and carrying case, choose Koss Porta Pro Black.
Koss CL/20i vs Koss Porta Pro Black at a Glance
• Koss CL/20i’s biggest strength: a transparent retro design, plush leatherette cushions, and in-line call and music controls. Trade-off: its cable and 3.5 mm connection limit wireless freedom.
• Koss Porta Pro Black’s biggest strength: a collapsible frame, included carrying case, and adjustable comfort features. Trade-off: it has no listed in-line microphone, so it is less suited to handling calls or recording narration directly.
• Choose the CL/20i if you want wired headphones with an in-line mic and remote for a compatible device.
• Choose the Porta Pro Black if compact storage and an included case matter more than built-in call controls.
The CL/20i is the more practical choice when you want one wired pair for listening and basic call control. Its in-line microphone and remote can answer or end calls and manage music, including pausing, playing, and skipping tracks. The 3.5 mm plug connects to compatible smartphones, tablets, computers, and gaming devices.
Its transparent design gives it a distinctive 90s look, while the adjustable headband and leatherette cushions are aimed at a comfortable on-ear fit. Koss lists a frequency range of 30–20,000 Hz. Those details describe the product, but they don’t establish how it will sound on every recording or device.

The Porta Pro Black is designed around a different priority: carrying and storing the headphones easily. Its frame collapses, and a soft case is included. An adjustable headband and multi-pivoting ear plates provide ways to adjust how the on-ear headphones sit. Two temporal comfort pads are intended to shift pressure around the fit.
Koss lists a frequency range of 15 Hz–25 kHz and a 3.5 mm wired connection. The model has cable controls, but the supplied information does not identify an in-line microphone for calls or recording. That makes it harder to choose for vlogging when you want the headset itself to capture speech.
This is the more natural fit if you want wired headphones that fold down for a bag and come with a case. It may also appeal if the adjustable fit is a priority. Skip it if an in-line mic and call controls are central to your setup. Although Bluetooth appears in one product-information field, the listed connectivity is wired through a 3.5 mm jack; I would not treat this as a Bluetooth pair.
• Best for an in-line microphone → Koss CL/20i. It has a microphone on the cable for calls and compatible recording setups.
• Best for cable-based call controls → Koss CL/20i. Its remote handles calls and music functions.
• Best for a collapsible design → Koss Porta Pro Black. The folding construction makes it easier to store between listening sessions.
• Best for an included carrying case → Koss Porta Pro Black. The case is part of the listed package.
• Best for a transparent 90s-inspired look → Koss CL/20i. The clear design is the most obvious visual difference between these two.
• Best for adjustable on-ear fit features → Koss Porta Pro Black. Its headband, pivoting ear plates, and temporal comfort pads offer several fit adjustments.
• Best for a compatible vlogging setup that needs a cable mic → Koss CL/20i. Confirm the device accepts the 3.5 mm connection and works with the in-line microphone.
• Best for compact packing without a wireless connection → Koss Porta Pro Black. Its collapsible frame and case suit listeners who want to keep wired headphones together in a bag.
Neither model is described as sweatproof or open-ear. Both are on-ear headphones, so shoppers searching for sweatproof open ear headphones for vlogging should look beyond these two. And neither should be treated as multipoint earphones for vlogging: the listed connection is wired, with no multipoint Bluetooth feature.
The audio figures also need a careful read. The CL/20i is listed at 30–20,000 Hz, while the Porta Pro Black is listed at 15 Hz–25 kHz. A wider stated frequency range alone does not tell you which pair will sound better for your voice, music, or editing work. Fit, device compatibility, and the microphone requirement are more useful decision points here.
I’d choose the Koss CL/20i for a compatible, wired vlogging setup because its in-line microphone and remote make it the more useful of these two for calls and basic cable-side control.
The Porta Pro Black has the clearer advantage for storage, thanks to its collapsible design and included case.
But for vlogging, I’d put the mic ahead of portability.
That is why the CL/20i is my pick for this specific use.
The CL/20i is the more suitable option if your recording device accepts its 3.5 mm plug and works with its in-line microphone. The Porta Pro Black’s supplied details do not list a microphone.
Both are listed with wired 3.5 mm connectivity. The Porta Pro Black has an inconsistent Bluetooth entry in its product information, but its stated connection is wired; I would not choose it expecting wireless use.
The Porta Pro Black is the clear choice for compact storage. It collapses and includes a carrying case, while those features are not listed for the CL/20i.
Koss lists 30–20,000 Hz for the CL/20i and 15 Hz–25 kHz for the Porta Pro Black. Those figures show different stated frequency ranges, but they do not by themselves establish which one will sound better to you.
