They have what i would describe as black square blocks on the end of them, and i cannot find them anywhere in the UK even on the internet. Would be grateful if anyone could help me, thanks&nbsp;</P> Sun, 02 Apr 2017 11:31:00 GMT https://community.sony.no/t5/portable-audio/sony-mdr-rf820r-headset-battery-question/m-p/2314868#M3492 Andycheyne1 2017-04-02T11:31:00Z https://community.sony.no/t5/portable-audio/sony-mdr-rf820r-headset-battery-question/m-p/2315047#M3493 <P>They seem to be available from Amazon...</P> <P>&nbsp;</P> <P><A href="https://www.amazon.co.uk/Replacement-Sony-MDR-IF240RK-MDR-IF540RK-MDR-RF885RK/dp/B002MPT0Y8/ref=pd_lpo_23_tr_t_3?_encoding=UTF8&amp;psc=1&amp;refRID=ZW01D6VC5NGWMTMDZF5T" target="_blank">https://www.amazon.co.uk/Replacement-Sony-MDR-IF240RK-MDR-IF540RK-MDR-RF885RK/dp/B002MPT0Y8/ref=pd_lpo_23_tr_t_3?_encoding=UTF8&amp;psc=1&amp;refRID=ZW01D6VC5NGWMTMDZF5T</A></P> <P>&nbsp;</P> Sun, 02 Apr 2017 20:15:32 GMT https://community.sony.no/t5/portable-audio/sony-mdr-rf820r-headset-battery-question/m-p/2315047#M3493 rich912 2017-04-02T20:15:32Z
