The stem came detached from the plug on both pairs and one stem remained lodged in my ear canal.
This is the third pair of these ear plugs I have purchased.  My husband and I had no issues with the other 2 pairs but I was wearing the third pair for the first time last night while working at a large NYE music festival and both malfunctioned.  The stem came detached from the plug on both pairs and one stem remained lodged in my ear canal.  I could not get it out with my fingers and trying to get it out only pushed it further and further into my ear and caused pain and discomfort.  Unfortunately I was at a paid photography gig and could not miss my assigned acts and I had to stand directly in front of numerous giant speakers with no ear protection for an extended time due to this.  At a break I had to go to a medical tent to have the stem removed.  Fortunately they gave me a different pair of plugs to wear for the rest of the concert.  It has not been 30 days since I bought these, but I cannot easily find a way to contact the seller about these issues via my orders in Amazon.  Now I am also scared to use any of the three pairs and risk this happening again.  It is the next day after the concert and my left ear is still sore and tender from this.  I feel I was close to damaging my ear drum and that is scary.  It was very uncomfortable to have the medical staff digging around in my ear with the tweezers to remove the stem as it was quite deep in my ear canal.
