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.Verified purchase

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.

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.Verified purchase

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. -

Was die Akkus leisten und wie lange wird sich zeigen. Aber bei dem Preis kann man sicher auch keine Wunderdinge erwarten. -

The batteries arrived correctly and quickly. I've used both. There is nothing to criticize. The price is also very consumer-friendly in comparison. Battery pass and voucher are useful. I'll shop here again.

I've been buying this product from Subtel for years. These compatible batteries allow me to continue to use my headphones which are no longer manufactured. Subtel is reliable, fast delivery. I would recommend this supplier.

Was delivered quickly. Of course, I can't comment on the shelf life.
What bothered me: the instruction leaflet is a joke. You can't even read it with a magnifying glass! Less is more!This review was translated automatically. Source language wasWurde schnell geliefert. Zur Haltbarkeit kann ich natürlich keine Aussage machen.
Was mich gestört hat: der Beipackzettel ist eine Verarschung. Nicht mal mit dem Vergrößerungsglas kann man diesen lesen! Da ist weniger mehr!
