If you have even a corner lamp on near you, it goes away. I would only recommend this product if you are super constrained on a budget, otherwise I would just spend a bit more on a pair of headphones with far better build quality and comfort. I found these to work quite well. Had to replace them, so bought new ones. The ankle strap is a bit big and I may just have to wear it out a little for it to fit properly but it’s adjustable. To me this wasnt the most pleasent sound profile. I like them because they look fashionable but have a lower block heel. Might be obvious to some of you but they really put in perspective the still limited audio quality of streaming over bluetooth. I love these ear buds I even dropped it in a glass of water and they work perfectly after that best ear buds out thanks so much I bought this for my Daughter cause shes starting daycare and will be doing remote learning there.
