Business ProfileforSennheiser PRO

I purchased the Sennheiser ******** **** Wireless 3 earbuds from **** *** on 05/28/22 for $249 - $170 BB Certificate. (receipt attached) In September 2023 both earbuds became un-responsive and wouldn't turn on or charge. I contacted Sennheiser support on 10/01/2023 and opened case number ************. Sennheiser Hearing responded on 10/04/2023 and told me to send my broken earbuds to ****** ******** ******* **** *** * ********** ***** *** **** ** ****** I opened RMA order ******** SR, RMA Reference Number ************ and paid $11.29 to ship the earbuds via ****. Tracking number ******************************. It was delivered on October 10 2023. After not hearing from ****** Consumer Hearing USA. I contacted Sennheiser Hearing asking about an update. They informed me that the earbuds had been received and I just needed to wait. On 11/04/2023 6:15pm I just happened to look outside my door and a package had been left. I never received any shipping confirmation or ***** tracking number. Just an invoice. (attached) Inside was a pair for Sennheiser ******** **** Wireless 3 earbuds in a sealed box. I opened the box and charged the earbuds for one hour. After one hour I checked both earbuds and noticed that the left earbud was unresponsive, did not light up and wouldn’t charge. This is the very same issue as the last Sennheiser ******** **** Wireless 3 earbuds. Also, It appears that this is a known defect and many other customers are having the same issue with their Sennheiser ******** **** Wireless 3 earbuds. I would like a $249 refund for the Sennheiser ******** **** Wireless 3 earbuds and $11.29 I wasted for **** shipping. I won't charge for the sales tax. Total is $260.29
