Frequently Asked Questions

Can a budget IEM still deliver good sound?

Absolutely. In recent years, the budget IEM market has become incredibly competitive, leading to significant improvements in sound quality even under $100. Many manufacturers now utilize efficient dynamic drivers, clever tuning techniques, and simplified but effective acoustic designs to produce clear, enjoyable sound without breaking the bank. While you might sacrifice build materials, cable quality, or extreme detail retrieval, many budget sets outperform older flagship models from previous generations. They're often more than sufficient for casual listeners, gamers, or anyone exploring the hobby for the first time.

What makes planar magnetic IEMs unique?

Planar magnetic drivers use a flat diaphragm with embedded conductive traces suspended in a magnetic field. This results in extremely fast response times, low distortion, and a clean, neutral sound signature. They're known for exceptional detail and imaging, though they may require more power. Planar IEMs often appeal to listeners who value accuracy and texture.

Does this IEM have a wide soundstage?

Yes, it offers an expansive, immersive soundstage that makes instruments and vocals feel spread out and layered in space. This is great for orchestral recordings, movie soundtracks, or live performances where spatial depth enhances the experience.
