NWOT or Outside Box: Phonak Serenity Choice Sleep KI25 (first & last photo stock photos) In the box • 2 ear tips of each size S, M, L • Two acoustic filters 24 dB • Aluminum key-ring carrying case • Multilingual manual Serenity Choice™ Sleep is designed to allow air to enter the ear. This has two advantages over competing products; - Limits or stops that uncomfortable ‘hot’ irritation feeling in your ear. - Helps reduce the feeling of ‘hearing your pulse’ caused by restricting blood flow in the ear, especially noticeable when laying on your side. Sleeping with ear tips will take a little getting used to, as it can sound unnaturally quiet for the first night. After that you’ll wonder why you didn’t use them earlier.
