It appears that some people are receiving a different item than others. I specifically purchased these hats because the photos people were posting in their reviews showed the hat with the little logo on it, and that is what I was looking for. The hats I received have no logo. I am not sure why two different products are being sent out - zero quality control!

I have had many Bluetooth's and this one is the best so far. The sound barrier has been the most important part. When I have both ear buds in I cant hear any outside voices or anybody close to me in distance. It's important to me. My boyfriend is in Texas and when we video chat I need to hear him and only him and these allow me to do just that. Thank you wireless earbuds.

Just received these was really upset that these did not fit .. I changed the ear tips but they would not stay in my ears . I was really looking forward to using these.
