Enjoy Sennheiser's top-quality wireless earbuds on your iPhone! We're offering a great deal on a set including the high-performance, genuine BTD600 dongle that transmits via aptX Adaptive. This set also includes a Lightning to USB-A camera connection kit for iPhone 14 and earlier models, plus connectors for Micro USB and USB-C connections. While there's a small dent on the left earbud, the rest is in excellent condition. All accessories are included. I've fallen into the TWS rabbit hole and own over 10 other models, as well as an iFi GO pod for wireless custom IEMs, so I haven't used these much. I also set the charging to 80%, so the battery hasn't been heavily used. Since the poorly-reviewed FiiO BT11 works well with my phone, I'm including it in this set as well. You likely won't find this set for under 20,000 yen, so I hope you can enjoy your summer vacation with great music! - Brand: Sennheiser - Model: Momentum True Wireless 4 - Included: BTD600 Thank you for looking.
