9 June 2025 – Oulu, Finland – Soundless Ltd proudly announces the launch of QuietOn 4, the latest evolution of active noise cancelling (ANC) sleep earbuds. Designed to deliver deeper, uninterrupted sleep. QuietOn 4 combines cutting edge ANC performance with a sleek, ergonomic form factor and superior comfort.
QuietOn 4 uses a high precision microphone and speaker system to sample ambient noise and generate phase shifted waveforms that cancel out low frequency sounds such as snoring, traffic, and home appliances. Unlike many sleep aids that rely on sound masking, such as white, pink, or brown noise, QuietOn 4 uses true ANC technology to eliminate disturbing low frequency sounds without adding any artificial noise. This ensures a quieter and more restful experience.
The design of QuietOn 4 has been refined to follow the natural oval contour of the ear canal, providing a secure and comfortable fit for all night wear, even for side sleepers. The earbuds feature custom designed Comply™ memory foam ear tips with integrated wax guards that help maintain cleanliness over time. The memory ear tips gently expand to form an airtight seal with minimal pressure. This enhances both comfort and acoustic performance while resisting sweat and maintaining shape over time. The included charging case provides up to 28 hours of earbuds use on a single charge. The earbuds automatically switch from hearing mode to ANC mode within 15 seconds of removal from the case, ensuring a seamless and intuitive user experience.
“Our mission has always been to help people experience the power of sleeping in silence,” said Janne Kyllönen, CPO and Co-Founder of Soundless. “With QuietOn 4, we’ve taken a major leap forward—not just in technology, but in how we support better sleep and overall well-being. We’re proud to offer a solution that’s both powerful and beautifully simple.”
QuietOn 4 is designed for anyone seeking haven of quiet in a noisy world. It’s especially beneficial for people who sleep next to a snoring partner, light sleepers who are sensitive to ambient noise, and travellers needing peace and quiet on planes or in hotels. It’s also ideal for shift workers who sleep during the day and individuals living in noisy urban environments. With its compact design, advanced ANC technology, and all-night comfort, QuietOn 4 offers a practical and effective solution for a wide range of sleep challenges.
QuietOn 4 is available globally through a network of trusted distributors, making it easy for customers to access the product wherever they are. More information on www.quieton.com
