What reviewers said
1MORE E1001
The 1MORE E1001 is a wired hybrid in-ear monitor that pairs a 16mm dynamic driver with two balanced armatures to deliver a rich, detailed sound signature at a budget-friendly price. Its all-metal build, comfortable fit, and generous accessory package make it a compelling pick for listeners seeking premium features without the premium cost. While its tuning is generally balanced and engaging, it does have some minor limitations in soundstage width and cable handling.

- Pro:Solid all-metal construction with a premium feel
- Pro:Comfortable, secure fit for extended listening
- Con:Cable is prone to noticeable microphonics
- Con:Soundstage feels somewhat narrow and intimate
