  • Hans Switzerland

    The batteries are used in Sennheiser headphones. They fit perfectly. We hope they will provide reliable and long-lasting performance.
    Service: Unfortunately, we did not receive an email notification to let us know when the delivery was on its way. This is very important, as the post office simply leaves the parcel in the letterbox without ringing the doorbell. After all, it needs to be delivered quickly. We would be very grateful if a little more attention could be paid to this request.

    First purchase and pleasantly surprised. I do not usually leave ebay but the store is highly recommended. Better price than on ebay and very fast shipping to the Canary Islands without any problem with customs (with "normal" Post Office) and the processing and shipping time of the order is less than 24 hours. The batteries work as the original did at the time. They are a quality replacement with 100x100 compatibility with my Sennheiser. Very satisfied.

    Given the type of battery, it arrived exactly as requested, I mounted it on the device, completed charging, after which everything worked smoothly, just as it was supposed to, and unfortunately with other suppliers this was not precisely the case.

    Fast delivery, despite inquiries from the shop because there were ambiguities with the address - so far everything ok Fit into the RS4200 as specified. What the batteries can do and how long remains to be seen. But at the price you can't expect miracles either.

    Die Akkus werden für Sennheiser Kopfhörer verwendet. Sie passen einwandfrei. Wir hoffen auf einen zuverlässigen und langen Betrieb.
    Service: Leider haben wir keine Mitteilung per Email erhalten, wann die Lieferung unterwegs ist. Es ist sehr wichtig, da die Post das Paket einfach in den Briefkasten legt, ohne zu läuten. Es muss ja schnell gehen. Vielen Dank, wenn diesem Wunsch etwas mehr Aufmerksamkeit geschenkt wird.

    Primera compra y gratamente sorprendido. No suelo salirme de ebay pero la tienda es muy recomendable. Mejor pecio que en ebay y envío rapidísimo a Canarias sin ningún problema con aduanas (con Correos "normal") y el tiempo de procesamiento y envió del pedido inferior a 24 horas. Las baterías funcionan como lo hacía la original en su momento. Son un reemplazo de calidad con compatibilidad 100x100 con mi Sennheiser. Muy satisfecho.

    schnelle Lieferung, trotz Rückfrage vom Shop da es Unklarheiten mit der Adresse gab- soweit alles ok. Passen wie angegeben in das RS4200. Was die Akkus leisten und wie lange wird sich zeigen. Aber bei dem Preis kann man sicher auch keine Wunderdinge erwarten.
