My old ones you couldnt. Good value for money excellent customer service would highly recommend for those who own a caravan. By the time I noticed he had already performed his sleight-of-mouth and ?vanished? one of the rubber ear tips. My wife loved them so we bought another 3 packs. Its early days and ive only worn these around the house, but Im already impressed with their support and comfort. I expanded them to there limits and they hold 5. They came and they were perfect, so comfortable and elegant. I think from constantly pulling them on and off switching between the Apple silicone ones and these Foam Masters I prematurely wore the plastic female indent which holds them securely to the air pod speaker which was causing them to not hold as tightly to the speaker as when they were new. Will be buying the black! Comfortable look beautiful and look great with allOutfits.
