Review on Canceling TENNMAK PRO ANC Bluetooth Cancelling by Carmen Winters

Revainrating 1 out of 5

Warning: Product design issues.

Hi I hope this is a good choice but in the end I'm disappointed. The device arrived fully charged according to the indicators. The device quickly "paired" with my iPhone 11, but something is wrong with the product's firmware, which doesn't allow pairing. Audio was not played. iPhone struggled to connect (sometimes freezes and heats up). A message appeared on the iPhone that the connection to the device was faulty and made me forget the Bluetooth pairing. Finally, I was able to connect the audio by activating the "Check Earbuds" multiple times. Downtime = 20 minutes. And unfortunately I have to repeat this whole procedure whenever I want to use it. This product was simply not tested extensively prior to release. Other problems too. The left listener is dead. After the diagnosis, I concluded that the left was never prosecuted in the case. Mechanically, the design deviates by a fraction of an inch, so there is no electrical contact inside the case. I was able to push it down by putting some foam inside, but now I have to use a rubber band to keep the case closed. And I've only had them for two days. My expectations that they last longer are not high.

Pros
  • Headphones
Cons
  • Not sure
