Compare published driver, impedance, sensitivity, cable, tuning-reference, and price-range information for popular IEMs under $50.
What This Guide Can and Cannot Tell You
This guide compares manufacturer-published specifications and current price ranges. It is not a GK blind listening test, measurement ranking, or claim that one model is objectively better. Prices and availability change, so check the linked product or manufacturer page before buying.

How to Use the Specifications
Driver configuration describes the hardware architecture, not guaranteed sound quality. Impedance and sensitivity help estimate source compatibility, but the published values may use different test methods. Tuning-reference labels are manufacturer or database descriptors and are not substitutes for comparable frequency-response measurements.
Practical Purchase Checks
- Confirm the current price, connector, cable type, included tips, and return policy on the seller page.
- Check whether your phone requires a USB-C or Lightning adapter.
- Prioritize fit and replaceable cables when long-term use matters.
- Use a pairwise comparison page to inspect published fields without treating a higher driver count as a quality score.
Where GK Products Fit
GK KUNTEN and GK G3 are included because GK publishes and sells these models. Their placement in this guide is not an independent endorsement. Visit the IEM specification library for the same fields across all listed models, or open the linked product page for current first-party information.
