I was super happy when I bought this boat rockerz 235 wireless earphone but after using 15 days I must have to admin that it's a basic brand with overhyped marketing. Certain brands make their research first then they launch products but it seems boat first launch product then reseach.
This earphone is good in sound and design but very bad in mic. You have to keep saying again and again to make other person hear your words. If you silent an unwanted call from mobile, your earphone keep vibrating like hell. Even if you are an important call and another waiting call comes up then again it keeps vibrating very hard and current call person get very much disturbance with the vibration through mic. Very small detailings are missing which make it weird. And top of that it vibration is too much irritating.
I don't know about other models. But I have taken 3 models from boat ( one is discontinue now) , this one is worst among that. Buy of you get it under 800/- otherwise don't go for this.
