I owned one of these before. Great sound for both parties. Good stereo sound with headphones. Great value for stero blue tooth. Started failing about within first year. Since they were just sitting in car cup holder, I accidentally dropped the main piece and stepped on it. Tried to purchase from EShop on Rakuten, but they sent me a cheaper model, were slow to return my response, and attempted bait and switch.. I'll definitely look for another one of these from shop with integrity.
