I purchased my first set of earphones about 6 months ago and after a few times of use they started to cut out, so I returned them to the shop where I bought them and exchanged them for a new pair.

At the first time of use they also cut out after about 4 minutes, but as it was Christmas and we were going away I was going to leave returning them until we returned.

Unfortunately when we returned we had suffered a burst pipe and were out out the house for 5 months, hence the delay in sorting the earphones out. I again returned to the store and they obligingly replaced these earphones,MDR-RF810RK, I charged them up overnight and tried them this morning

, you've guest it they cut out after about 4 minutes. Is it me or is there something inherently wrong with this particular model.
