Long listening sessions where fit is the first priority.

  • Limited tip sizes

Also consider

Fictional Relay Mini and Common Ground C2.

Introduction

This review intentionally has no measurement section so readers and editors can see how that absence is disclosed.

Design and build

The compact shells sit flush, and the replaceable cable uses a common connector.

Listening impressions

Subjective notes describe a mild upper-bass emphasis and smooth treble. Without measurement data, the wording remains appropriately qualified.

Limitations

The lack of measurements reduces confidence in comparisons and unit consistency.

Conclusion

A comfortable fictional option, presented with the evidence boundary clearly visible.
