This is the Sennheiser MOMENTUM True Wireless 3, a wireless noise-canceling earphone. I purchased it from Amazon US in July 2023. It lived up to its flagship (at the time) performance, but unfortunately, the shape didn't fit my ears well, so I didn't use it much. I'm selling it now because I've purchased a different model (Apple AirPods) and no longer have a need for it. ・Everything in the first photo is included (earphone body, charging case, charging cable (unused), ear tip set, ear fin set, outer box, and documents). ・I believe there are no noticeable scratches or stains, but please judge for yourself from the photos. ・I tested the functionality, from pairing to sound output (video recorded), and then performed a factory reset just before listing. ・Please understand that this is a sale of an item that was personally used by an amateur. I have done my best to ensure that the buyer will be satisfied, such as by performing the aforementioned functionality check and cleaning the item, considering it's something you wear. However, I cannot guarantee that it will meet everyone's expectations 100%. Those seeking perfection or who are overly concerned about details should refrain from purchasing and consider buying from a professional seller. ・I cannot accept price reduction requests. Thank you for your consideration.
