I have trouble settling for sleep and getting back to sleep.
Having read the overall positive reviews, I dug deep and purchased a pair. After all, if it works, it's worth it.
I'm starting off with the bad news - Active Noise Cancelling is ineffective. It is truly disappointing when the sleep exercises in the Kokoon app has done its bit, and I'm distracted by a cawing crow or a passing ambulance in the distance. Any other headphone would be able to deal with these noises. By design, over-ear headphones are still better than other headphones at reducing noise, but ANC is simply not working.
Beautiful in grey, but the materials are flawed. Fabric earpieces are detachable and washable, but the band of the headset is also wrapped in fabric. This should either be made from a wipe-down material, or it should be washable. Despite great care, I have already marked this lightly.
Snug, and I can rest my head lightly on the side of the headphones. Kokoon are more comfortable than other headphones, but hurts my ears after prolonged wear. I end up waking up to take them off in the middle of the night.
Quality and simple exercises. I bought the headphones to listen to Sleepcasts from Headspace (paid subscription), so I end up using both.
In the end, a pair of Apple Airpod Pros resolved all the above issues. However, over-ear headphones are debatably better for ear health than in-ear headphones.
Overall, the Kokoon can help me sleep - on occasion. I enjoy having a dedicated pair of headphones that I associate with sleep. However, taking the price into account, it's hard to justify when I bought it for its noise-canceling abilities.
Length of Use: 6–12 months
Bottom Line: No, I would not recommend this to a friend
