About the Radsone HE100 IEM
Radsone earned an excellent reputation in the audiophile community with the ES100 Bluetooth DAC/amp. Now, the company is bringing coveted sound directly to your ears with the EarStudio HE100 IEM, which is great for pairing with the ES100 or ES100 MK2—or using on the go. The HE100 features a single Hi-Res dynamic driver that minimizes partial vibration sometimes found in IEMs, while clearly articulating across all frequencies (especially high frequencies). Topped off with an aluminum housing that’s both durable and lightweight, the HE100 is a great choice for immersive listening wherever you go. As Major HiFi’s review puts it: "If you’re looking for a well-balanced sound, and a flood of detail, the Radsone Earstudio HE100 will not disappoint."
