Recognised by the Red Dot Award 2026, alongside ALT Watch 1. Pre-book ALT Buds Open: Open by design ALT Buds Open sits outside the ear canal. That single design decision shapes everything else about the product. You hear your music, but you also hear the door, the traffic, the colleague walking up to your desk. For the long stretches of the day where you want sound without the full disconnect of an in-ear seal, it’s the right form. It’s also the form that’s easiest to wear for hours. No fatigue from a tight seal, no pressure changes, no swapping ear tips to find a fit that works. The audio, in detail Inside the form, ALT Buds Open carries a 13mm driver, the largest in the ALT audio lineup. A bigger driver moves more air, which translates to a fuller low end and a wider sense of space. Audio is Hi-Res Audio certified, the standard that signals the product can reproduce frequencies beyond CD quality when paired with a compatible source. LHDC codec support handles the wireless side: higher-resolution audio over Bluetooth, less compression loss, more of what the artist actually put in the track. The Sound There’s no ANC on ALT Buds Open. The whole point of an open form is to keep the world in. What it carries instead is a 4-mic ENC system driven by an AI DNN (deep neural network) algorithm. The network learns the difference between your voice and the noise around it. On a call, you sound like you, even on a station platform, even on a windy walk. {Insert image} Battery and charge Playback runs up to 35 hours. InstaCharge delivers 3.2 hours of playback on a 10-minute top-up. Enough to cover a commute, a workout, or a long call without the conversation about charging. The rest of the spec Bluetooth 6.0 with dual-device pairing. Switch between phone and laptop without re-pairing. AI-assisted features built into the experience. Customisable EQ through the Noise Audio App. The uninterrupted ALT design line runs across the product. The same signature that connects every device in the series.
