radius HP-NE30C Launches July 4: Noise-Cancelling Hi-Res USB-C Earphones for 5,500 Yen

radius will release the HP-NE30C, a USB-C wired earphone with active noise cancelling, on July 4, 2026. It plugs straight into the USB-C port of a smartphone or tablet and draws power from the device, so the earphones themselves never need charging. Combining feedforward noise cancelling, hi-res playback up to 24bit/96kHz, and a uniquely shaped ear tip, the price is held to 5,500 yen (tax included). In an era dominated by true wireless models, it deliberately leans into the simplicity and stability that only a wired design can offer.

USB-C with no charging, and no worries about running out of battery

The defining trait of the HP-NE30C is its USB-C connection, which draws power from the connected device. Because there is no battery inside the earphones, there is no need to charge them beforehand or worry about running flat while you are out. Even on long trips by shinkansen or plane, you can keep noise cancelling switched on the whole way.

The noise cancelling uses a feedforward design: microphones built into the left and right earpieces pick up ambient noise, then generate a sound in the opposite phase to cancel it out. It keeps music and calls easy to hear in noisy places such as trains, station concourses, busy streets, and cafes. It also includes an ambient sound mode that lets in surrounding sound while the earphones stay in place, so you can respond to station announcements or a sudden conversation without taking them out.

A wired connection also brings the advantage of minimal latency. Unlike wireless connections such as Bluetooth, it is less affected by radio interference and transmission delay, so audio stays in sync with lip movements when watching video, and the gap between on-screen action and sound is kept small in rhythm and action games.

A uniquely shaped "Deep Mount Earpiece" that boosts isolation

For the ear tips, which greatly affect the fit, radius adopted its own "Deep Mount Earpiece." Its shape fits over a wider area deeper in the ear than a typical ear tip, improving the seal to deliver both rich bass and a stable fit.

It also provides passive noise cancelling that physically blocks outside sound, and combined with the electronic noise cancelling, the two work together for higher isolation. The texture differs by color: the white HP-NE30CW is clear with a high sense of contact against the ear, while the black HP-NE30CK is matte for a smooth, dry feel. Four sizes of ear tips are included (XS, S, M, and L) so you can match them to your ears.

Hi-res support and a multifunction remote balance sound and control

On the audio side, it packs a high-performance DAC that supports hi-res playback up to 24bit/96kHz, along with a 12mm dynamic driver. Simply connect a compatible source and you get balanced sound that renders even fine nuances. The frequency response is 20Hz to 40,000Hz, impedance is 32 ohms, and the output sound pressure level is 108±1dB/mW.

The cable carries a multifunction remote with a microphone for calls. At your fingertips you can play and pause, skip forward and back, adjust volume, switch between noise cancelling, ambient sound, and normal modes, answer and end calls, and summon a voice assistant. The cable jacket uses a soft TPE material that reduces touch noise from rubbing against clothing, and the included cable clip lets you fasten it to your clothes to curb cable sway. The cable is about 120cm long in a Y shape, and the weight is about 18g including the cable.

There is also a bonus for enjoying hi-res audio. While the HP-NE30C is connected, you can use the hi-res playback feature of the free "NePLAYER Lite" app at no extra charge, even though it normally requires a purchase.

Price, colors, and release date

The HP-NE30C goes on sale July 4, 2026, at an estimated street price of 5,500 yen (tax included). It comes in two colors, white (HP-NE30CW) and black (HP-NE30CK). Included accessories are the Deep Mount Earpieces (one set each in XS, S, M, and L), a cable clip, and an instruction manual (warranty).

Summary

The HP-NE30C is a wired earphone that combines a charge-free USB-C connection with feedforward noise cancelling and ambient sound, hi-res support up to 24bit/96kHz, and the uniquely shaped Deep Mount Earpiece. It also features a multifunction remote and microphone, all held to 5,500 yen (tax included). On a different axis from the convenience of true wireless, it looks like an easy-to-handle option for anyone who wants to avoid dead batteries and unstable connections.
