Description of the Sennheiser MOMENTUM True Wireless 3 in black. All accessories are included. The cable has not been used. Purchased in July 2023 and used for about a year, alternating with other earphones. I mainly used other earphones, but since I've used these for about a year, there is a sense of use. The battery seems to have diminished compared to when it was new, but I think it's still perfectly usable. I haven't used them at all recently, so I'm putting them up for sale. I have cleaned any dirt as much as possible. Description of the Sennheiser Bluetooth transmitter BTD 600 USB adapter aptX Adaptive Bluetooth 5.2. Purchased on Amazon in December 2023 and used, but I haven't used it much, so it's almost like new. I used it with the Sennheiser MOMENTUM True Wireless 3. All accessories, including the manual, are included. #SENNHEISER #Sennheiser #WirelessEarphones #WirelessHeadphones #Earphones #Headphones #btd600 #usbc #usba
