8 Large (L) Ergonomical Comfort Replacement Set Earbuds Eartips Compatible with Sennheiser IE Series, CX Series, CXC Series, CXL Series, OCX Series, and MM Series in Ear Earphone Headsets

Worked as promised. Quality is acceptable and they come in a small plastic box to save the extras until needed.

I bought a set of the Sennheiser OCX 685i Adidas Sports In-Ear Headphones - Black at a local store and was absolutely loving them. They're great headphones for working out; lifting weights, running, whatever. They come with 3 different sets of eartips (the squishy part that keeps the hard plastic music tube in your ear), small medium and large. I was wearing the large size, which were great, but one day when I pulled the headphones out of my pockets, one of the eartips slipped off, and disappeared forever. I swapped them out for the mediums, because I was at a MOB Station about to be deployed, and didn't have time to get new headphones or order new eartips online. Well, the mediums kind of sucked for me. They weren't wide enough to completely fill my ear canal, so a lot of ambient noise would enter, and the only way I could block out the other sounds of the gym was to have my music so loud that it gave me a headache. Well, I started looking on amazon for replacement eartips, and found a lot of off-brand parts that are supposed to work for this brand, and that brand, and this other. Well, I didn't want eartips that were going to kind of work for a lot of different earbuds; I wanted the one pair that was going to work great for my earbuds (Sennheiser OCX 685i). I ordered this 8 pack of large replacements directly from Sennheiser, and I do not regret it at all. Instantly the sound quality on my music seemed improved; or rather, it returned to the quality I had before I went to the medium eartips. And now I keep some spares in my gym bag, so that should I ever lose another one, I'll instantly have a replacement. 5/5, would buy again!

They arrived two days earlier than stated, and that was a great first impression. They seem as good (or better) quality than the ones they are replacing. Of course the main test is the sound. The one side that I did not lose I left on my CX 880i ear buds, and put the new one on the other side for a legitimate side by side comparison. The quality is as good or better. These actually make the lows come out more. The highs are about the same. Overall these are definitely worth the price and I would recommend them to others.

Good product they are nice and comfortable good quality
