    I purchased this product for video conferencing for work. While the audio coming in was acceptable, not great, but acceptable, there was a metallic buzzing on the microphone / audio out signal. I tried several connection methods and devices but the buzzing remained. I do not recommend this product.

    I purchased headphones at a higher price expecting a better quality and was met with really awful function. Every person complains they can not hear me and I hear constant static on my end. Hoping I can find the time to return these before the time runs out.

    It is literally like wearing a microphone and an earpiece around my neck. The person I am talking to can hear the friction of the headphone rubbing against my clothes while I am moving about. I can hear it in my won ear also. Everyone says I sound muffled or distorted. They are bulky for headphones around the neck.

    After just two months, these head phones no longered operated the right way. First the blue tooth would act funny, then to only one ear bud would work and the other would go in and out to stop working entirely. No longer wants to charge either. Not worth the trouble.

    Brought this item about 1 month ago and I am not satisfied with it. Have been informed that there is a lot of noise on the receiving end with feed back also. Would not recommend this item to anybody. Would like to return this item and my money reimbursed.

    I had never had this style before. Doesn’t cancel out noise very well. I would get complaints when I was talking on the phone. I also didn’t like it being around my neck as it became annoying. Then I decided I wanted something more compact and less invasive so I returned them within a week.
