Music engineered to help you focus, relax and sleep better. Sollos combines instrumental music from some of the world’s best-known artists with cognitive science and auditory technology designed to support your wellbeing. Listen to specially engineered instrumental playlists from artists including The Weeknd, Post Malone, Selena Gomez, Olivia Dean and Ludovico Einaudi, alongside extended mixes for relaxation, sleep and meditation. There are immersive nature soundscapes too. Everything is organised around three goals: Focus, Relax and Sleep. Sollos is free to download. An active Apple Music subscription or trial is required to unlock the full catalogue. In selected territories, a smaller collection is also available without Apple Music. MORE THAN A PLAYLIST Sollos doesn’t just help you find music. It helps you discover what works for you. Check in with how you’re feeling before and after you listen, compare how you feel across different sessions, and easily return to the audio that works best for you. Explore by goal, see what other Sollos listeners are enjoying, and discover new music for the state of mind you want. MUSIC, RE-ENGINEERED FOR WELLBEING Our cognitive scientists and music experts select and create instrumental music using research into how features such as tempo, harmony, texture and acoustic properties influence attention, relaxation and sleep. We then blend auditory beats into the music to support different listening goals. BACKED BY RESEARCH Sollos is informed by decades of scientific research and our own in-house cognitive science programme. In a published, peer-reviewed study of 308 participants, 30 minutes of Sollos music blended with monaural beats significantly reduced anxiety and improved mood compared with a control group. Our 2025 Listening Impact Study also found: • 91.5% of users reported improved focus after at least 20 mins of listening • 91.9% of users felt more chilled after a single Relax session • Poor sleepers who listened regularly for four weeks reported around an extra hour of sleep per night FOCUS Get into the zone for work, study or anything that needs your full attention. Our Focus music uses gamma auditory beats, which research has linked to improvements in cognitive performance, working memory and creative thinking, alongside carefully selected sonic textures and tempos. “When I start listening to the music I start focusing almost immediately, it's like a wake-up call, and then my mind settles gently into the task.” – a Sollos listener RELAX Switch off, decompress and make space for yourself. Our Relax music uses theta auditory beats for reduced anxiety and improved mood, alongside nature soundscapes designed for calmer listening. “Sollos has been a secret weapon…ready to cure my stress and calm me down” – a Sollos listener SLEEP Wind down at bedtime, drift off or soundtrack a restorative nap. Our Sleep mixes use delta auditory beats and pink noise, which research has linked with better sleep quality and longer, deeper sleep. Some mixes are designed to move gradually from recognisable instrumental music towards near-silence as you wind down. “Sollos became an essential part of my nightly routine” – a Sollos listener MUSIC FOR EVERY KIND OF LISTENER The Sollos catalogue crosses pop, electronic, R&B, hip hop, classical, ambient and more, giving you more ways to find instrumental music that fits both your taste and what you need in the moment. “I'd gone from not sleeping properly, not being able to focus or concentrate, and within 5 minutes of listening to the music it changed everything for me” – Megan, a Sollos listener Discover your soundtrack to a better state of mind.
