Connection type: Wireless Noise canceling: None Brand: Marshall Model name: Major Ⅳ Color: Black Headphone type: On-ear Connection method: Wireless 80 hours of continuous playback / Qi charging compatible / Call compatible Bluetooth I used it for about two weeks after purchasing it, but as you can see in the photo, the left metal fitting part is broken. There is no problem with the sound quality, and both sides are in working condition. I think it can be used normally if you fix it with adhesive. The instruction manual is included, but the charger is not included, so please contact me if you understand. #Marshall #Headphones #Earphones #Wireless
