I have Bose QC 35 II and I was looking for smaller headphone, I love music and will listen to it almost 16hours a day, When I saw this product I was scared to buy, but trust me it's a crime to buy something else!

I'm really happy for every part of the it: from the packaging itself, to the case, how they sit inside your ear and most important the audio quality!!!

Amazing battery life and color, Thank you for making such a great product in an amazing price!!

Got this headphones from knowheadphones. I really love the color of it. Plus the sounds quality is awesome. I would def love to recommend this to all my friends.

They easily passed my go-to headphones soundcheck of Garbage’s “Vow” - nice full, rich sound that allows the gorgeously layered mix to shine through. Also beautifully handled lush, sweeping orchestral instrumentals (Westworld OST, LOST OST). And they’re SO COMFORTABLE. I wear glasses, and have FINALLY found a pair of over-ear headphones that I can wear all day.

I have had my Know Calm headphones for almost a week now. I could not be happier with my purchase. First thing I noticed was the packaging. The packaging was super clean and nice and really made me felt like I bought an awesome product. They came with an awesome travel bag as well. The user manual was super easy to read an understand. Once they were charged, I mastered all the features within minutes. The sound quality for both music and podcasts is top notch. The sound is not overbearing which is great for when my kids want to listen to them. I feel safe with them on them. The reason the sound does not have to be overbearing is because the noise cancelation is unreal! It’s great for when I need to slip away from the madness of having four kids in the house, however it’s almost irresponsible for me to wear them around kids because it literally tunes out everything! In the short time I’ve had them, the battery life had been awesome and they can charge wirelessly by placing the left ear head phone on a my wireless charger. The comfort is also awesome. They are so comfortable that I can wear them laying down in my bed on my pillow. The last pair of over the ear headphones I owned I could not do that. Overall, this product is amazing and great for parents with kids!
