If you're serious about getting top-notch sound from your headphones while on the go, a portable DAC (Digital-to-Analog Converter) is pretty much a must-have. The iBasso Nunchaku steps into this space with a fresh take—offering more than just high-quality audio conversion. This compact USB-C DAC/amp doesn’t just upgrade your sound—it gives you the flexibility to choose between two distinct amplifier modes: solid-state for crisp, clean audio or analog tube for that warm, vintage vibe.

The standout feature of the iBasso Nunchaku is its dual amplifier system. With the twist of a knob, you can switch between solid-state and tube amplification, essentially offering two unique sound experiences in one device.

In solid-state mode, the Nunchaku uses modern Class A/B amplifier technology. This setup is perfect for daily listening—whether you’re on your commute or working at your desk—offering a clean, accurate sound with minimal noise interference. It’s reliable, efficient, and ideal for those who appreciate a straightforward, polished audio experience.

But if you’re craving something warmer and more analog, the tube mode has you covered. Powered by a pair of Raytheon JAN6418 tubes, this setting brings a richer, more lifelike quality to your music—perfect for those late-night listening sessions where you want every note to feel immersive. There’s even a small window that lets you watch the tubes glow while they work.

However, it’s worth noting that tube amps can be sensitive to physical movement, which means you might notice some unwanted noise (known as microphonics) if you jostle the device. iBasso has tried to minimize this by mounting the tubes with Poron polyurethane shock-absorbing material.

At its core, the Nunchaku is built for serious audio performance. It houses dual Cirrus Logic CS43198 DAC chips, known for their ability to handle high-resolution audio with precision and clarity. This little device supports PCM audio up to 32-bit/768kHz and DSD512 music streams, making it capable of handling some of the highest-quality audio files available.

In terms of technical specs, the Nunchaku boasts an impressive signal-to-noise ratio (SNR). In solid-state mode, it hits 130 dB, ensuring ultra-clean sound. Switch over to tube mode, and while the SNR drops to 107 dB, the trade-off is that warmer, more textured sound signature that tube enthusiasts love.

If you’re the type who likes to tweak your sound, the Nunchaku offers five customizable DAC filters. These let you adjust the audio output to suit different music genres or personal preferences, giving you even more control over your listening experience.

The Nunchaku isn’t just about performance—it’s got style too. Built from aluminum with dual tempered glass panels, it feels sleek and sturdy in hand. A 0.96-inch OLED display gives you all the vital stats at a glance, showing volume levels, sample rate, gain settings, and which amp mode you’re currently using. Navigating through settings is simple, thanks to a multi-function control knob that makes adjusting on the fly hassle-free.

In terms of size, this DAC is small but mighty. Measuring just 65 x 34.6 x 15 mm and weighing 50 grams, it’s light enough to slip into your pocket without a second thought. It also supports both 3.5mm single-ended and 4.4mm balanced headphone outputs, giving you flexibility for different headphone setups. The balanced output can deliver up to 525 mW at 32 ohms, meaning it can easily handle more demanding headphones.

The Nunchaku connects to your devices via USB-C, but it also comes with adapters for USB-A and Apple Lightning, so it’s compatible with a wide range of devices—whether you’re using an Android phone, an iPhone, or a laptop running macOS, Windows, or Linux. There’s even an optional app for Android users, which allows remote control of the DAC’s functions.

One thing to keep in mind: the Nunchaku doesn’t have a built-in battery. It draws power directly from your connected device, which helps keep the unit compact but also means it can drain your phone or laptop battery faster than you might expect. This could be a factor if you’re planning to use it on long trips without easy access to charging.

The iBasso Nunchaku is priced at $299 and comes in red or gray. Each unit also ships with a yellow leather carrying case.
