Thank you for viewing. This is the earphone case for the earfun EarFun Air Pro 4 (TW600). I no longer need it because I lost the earphones themselves. This is an offer for the case only. There are scratches and scuffs throughout, showing signs of use. There are particularly noticeable scratches on the bottom. The charging light illuminates, so it is usable. Please check the photos for details. - Brand: earfun - Color: Black - Model: EarFun Air Pro 4 ULTRA ANC (TW600)
