Test Results: Throughout a meticulous ten-week evaluation, 95% of our testers endorsed the earplugs’ efficiency in noise reduction, celebrating a peaceful sleeping environment. A standout feature is their ability to suppress disruptive background noises effectively while ensuring essential sounds like alarm clocks or a baby’s cry remain audible. Specifically designed for sleep, these earplugs excel in mitigating disturbances from snoring and urban traffic, marking a notable improvement in sleep disorders for our participants.

Remarkably, the earplugs are engineered to offer a sound reduction rating (SNR) of 24 dB, providing balanced protection across high (H=24 dB), medium (M=21 dB), and low (L=19 dB) frequencies. This comprehensive noise attenuation, as validated by ISO standard 4869-2 through independent German testing, ensures sleep is not just uninterrupted but genuinely restorative.

Leveraging BOLLSEN’s AR KI TECH, the earplugs are personalised to each user’s ear shape using augmented reality (AR) and artificial intelligence (AI), based on a simple photo. This innovative approach, costing only £12, stands in sharp contrast to traditional, more expensive custom fitting methods, delivering personalised ear protection that truly fits the unique contours of each user’s ears, further enhancing the sleep experience.

Overall Impression:
BOLLSEN earplugs distinctly outperform competitors by not only facilitating a noise-reduced sleep environment but also by promoting an overall improvement in life quality from the first night of use.
