RE400

The RE400 In-Ear Monitor is a wired earphone in HIFIMAN's entry range, aimed at listeners who want an inexpensive IEM for everyday listening. Customer reviews describe it as a good-value earphone that works well with an external DAC and is suitable as a gift.

The product listing shows four product images but gives no technical data such as driver type, impedance, sensitivity, frequency response, cable length or connector type. A reviewer notes that the package includes several accessories, but the listing does not itemise them.

The related RE400a model is listed alongside it as an in-line control earphone, which suggests the RE400 is the version without an in-line remote. The listing does not state this directly, so buyers should check the full details with the maker before relying on it.
