Beautiful design, terrible battery defect (100% failure rate)
Me and my girlfiend received two different pairs of GravaStar headphones as gifts (Sirius PRO P9). While the design is incredibly unique, the hardware quality is unacceptable. On both units, the batteries completely failed after minimal use, and now hold a charge for less than 5 minutes tops. When I contacted customer service, they confirmed the units are completely sealed and cannot be repaired. However, because these were gifts and I don't have the original order number, GravaStar refused to honor a warranty replacement—even though I provided the physical serial numbers proving they are authentic products. If you buy these, know that you are buying a disposable product. If the battery dies, or if you receive it as a gift, customer service will just offer you a discount code to spend more money on another faulty unit. Buyer beware. UPDATE! after the company’s public reply: I contacted GravaStar again exactly as requested and referenced this Trustpilot review. Unfortunately, despite the public statement about “reviewing the case” and “finding a better way forward,” the final outcome remained unchanged. The headphones still cannot be repaired because the units are sealed and no replacement batteries exist. Although I provided authentic serial-numbered products, GravaStar again refused warranty replacement because the headphones were gifts and I do not have the original order number. So to clarify for future buyers: the public response did not result in any actual resolution, exception, or replacement offer beyond another discount code to purchase a new unit. The design is great. The battery reliability and warranty support were not.
