Quick answer

If you want a straightforward wired earbud with deep bass and don't need call or track controls, choose the Koss CL-20. If you prefer an inline remote for taking calls and skipping songs, go with the Koss CL-20i.

What makes them similar?

Both the Koss CL-20 and CL-20i share the same clear transparent design with soft leatherette cushions. They also deliver the same audio signature: deep bass and crisp highs. The core listening experience is identical.

The one difference that matters

The CL-20i adds an in-line OneTouch remote that lets you take calls, pause/play music, and skip tracks. The standard CL-20 has no remote at all. If you frequently take calls through your earbuds or want to control playback without reaching for your device, the CL-20i is the practical upgrade. If you never use those features, the CL-20 saves you a few dollars.
