I prefer white, so I bought a white one. I haven't used Bluetooth headphones before. I didn't know how to do it until I read the instructions carefully. No matter how the headphones change, my biggest concern is still its comfort, sound quality, and battery life.
I get used to running at night, about an hour at a time, so the comfort of wearing headphones is particularly important to me. To test its comfort, I ran for an hour and a half wearing this headset. It's great. It was almost born for running.
First of all, when running, the i9s AirPods show no sign of getting out of the ear, there is no obvious distension in the ear, and the inside of the ear feels a little hot but acceptable, at least much better than my wired headphones. The headphone's mini earplugs ensure a certain degree of sound insulation and won't be completely inaudible while running.
Additionally, the headphones are waterproof. I sweat a lot when I run, but sweating doesn't affect the use of headphones at all. Since I used this headset, I don't have to struggle anymore. It's a lot easier to go out for a run, and it looks like my goal of "10 kilometers a day" can be achieved.
The sound quality of i9s TWS is similar to my previous headphones, there is no obvious distortion of sound. The headset reproduces great middle- and low-frequency sound, but the performance is less satisfying for high-frequency sound. This kind of price headphones, the effect is already very good. I am not a sound quality enthusiast, so the demand for sound quality is not high. As long as the sound is not distorted, I can accept it.
After fully charged, the Bluetooth headset can last about three hours and a half at a time, which is about the same as the time in the product specification. The battery life is satisfying. It is worth mentioning that its charging case is exquisite and lovely, and I like it very much. The moment I put the earphones back into the charging case, charging starts immediately.
Overall, I9s is a sports headset. What's more, it is budget-friendly for the general public. If you have a running plan but haven't started it yet, I suggest that you buy this headset which will make you fall in love with running.
