I'm in ❤️ with Shokz OpenDots One- Ear Headphones, this is my 2nd pair that i ordered within 6 months one in pink and the black OMG when i tell you the color charger black sleek shiny with a matte look with the Shokz logo in bedding right into the front cover😍 also you never have to worry about a mix up which one is the the right or left earbud, you can feel at ease to wear them in either ear, the frequency range surprisingly i went shopping in multiple places without carry around my charger left it in my car with the distance range from my car to walk was not close i was steel able to get good reception 😀 through out while talking with family members,for full charge time is 20 min, but quick charge is 10 min talk time superb i use my earbuds for work from 8am to 5pm. and from work i went to a dinner party that was over at 11pm. and still had talk time thereafter you can clean the earbuds and charger sensors once a week with a Q-tips with alcohol and dry, you can do this because these earbuds are water and sweat resistance along with noise canceling even better i forgot that i was wearing them there that comfortable no pain to the ears at all clip on easily and stays in place until you take them off 😀 i would definitely recommend.
