Digital Display Wireless Headphone Support TF Card Play Noise Cancel HiFi Stereo Bluetooth 5.4 Headset Painless Wear

The shipment of wireless headphones was delivered after 17 days. After unpacking, the control buttons did not work, the display was black. After charging to 100% and disconnecting the cable, the display is still not working, the charge level is only indicated when connected to the charger. The headphones only work with an audio cable connection, not wirelessly. Great disappointment, I do not recommend the supply chain, make up your own mind.
