Choosing IEM earphones means resolving a simple tension: do you want a lower-priced wired setup with a focused feature mix, or a more detailed design built around a different listening brief? The iKKO Lumina OH300 and Soara IEM by Kontinum take different routes. The useful payoff is a clear match: the OH300 concentrates on straightforward wired listening, while Soara puts more emphasis on its stated tuning and construction.
Quick verdict
Choose the iKKO Lumina OH300 when extra bass, noise isolation, a detachable cable, and a 3.5mm Jack are the priorities; it is listed at USD 39.99. Choose the Soara IEM by Kontinum when a balanced sound profile and three balanced armature drivers plus one dynamic driver matter more; its listed price is USD 399.99. Both use a wired in-ear format with 3.5mm Jack connectivity listed, so the central decision is the feature emphasis, condition, and price level rather than basic wired connection.

Product notes
iKKO Lumina OH300

The OH300's clearest draw is its photochromic glass faceplates: they shift color in sunlight and safeguard the internal tuning board and circuitry from UV radiation. Its expansive soundstage is another concrete reason to choose it if that presentation appeals. The limitation is the listed 1.2 m cable length; that specific reach may not suit every listening setup. The result is a focused pick for shoppers who want a distinctive faceplate detail and the stated soundstage without moving away from a simple wired format. Its black finish and new condition also give the package a straightforward presentation for everyday listening.
Soara IEM by Kontinum

Soara's reason to choose is its combination of rich, smooth, and punchy sound with crisp definition. Its 3D-printed chambers and 8-wire silver-plated oxygen-free copper cable provide specific design details, while the two 2-pin detachable cables add another concrete part of the package. The limitation is equally explicit: Soara is identified as "Without MIC." That no-microphone specification matters if calls or voice capture are part of your intended setup. For a listener who does not need an integrated mic, Soara's stated presentation and construction make a clear case; for voice use, the no-mic designation is the reason to look elsewhere.
Final choice by use case
- For casual music listening, mobile gaming, or mixing: choose the iKKO Lumina OH300, since those uses are directly associated with its feature brief.
- For audiophile or musician-focused listening: choose the Soara IEM by Kontinum, whose title names those audiences and whose design centers on a balanced presentation.
- For a new-condition purchase: choose the iKKO, which is marked New, while Soara is marked Open box.
The choice is straightforward: iKKO suits shoppers who want a focused wired setup and everyday uses, while Soara suits listeners who specifically want its audiophile-and-musician focus, stated presentation, and construction details.
