Purchased in August 2023. The left microphone became defective, so I'm selling this after replacing it. Used until September 17, 2025. The right microphone works, so calls are possible. The speakers also work on both sides, so you can listen to music, YouTube, etc. I will provide it with the case. The photos show the case attached. - Model Name: OPENFIT - Color: Black - Accessories: Charging case, charging cable I have lowered the price to ensure a smooth transaction, so please refrain from negotiating the price. ⭐︎ *Shipping may be delayed depending on the timing of the purchase. Please be aware of this beforehand.
