Just for some background info, the H2O Audio Interval comes with 5 pairs of soft round ear plugs in sizes XS, S, M, L and XL. I used both the L and XL earplugs. I was able to get a good seal, yet there were times when the ear plug would come out of my ear while swimming. I was doing a swim workout with intervals so I was testing how well the earplugs would stay in through some aggressive swimming.

Enter the H2O Audio Pro Fit Kit. It has 5 different styles within the 9 pairs of ear plugs. The styles are tree tip (3 layered, longer ear plug), dual tip (2 layered plug, shorter than the tree tip), stepped (narrower at the tip that enters the ear and wider at the base of the plug), memory foam (cylinder shape and as the name implies, it will shape to your ear’s opening and retain the shape) and the soft round (which is more of a standard ear plug; the same style that comes with the H2O Audio Interval). See pictures below of each of the styles.

9 Pairs of Ear Plugs available in the H2O Audio Pro Fit Kit |
I just tried out the large tree tip ear plug the other day. Similar to the shape of a tree, it is narrow at the top for entry into the ear and then the next 2 layers are wider. You definitely get a deeper fit with this ear plug, although not too deep to cause any discomfort or harm to the ear. You should be careful in inserting any of the ear plugs, and if you feel any discomfort you should remove the plug and try another one. I recommend pulling the top of your ear upwards with one hand to extend the opening to your ear while inserting the ear plug with the other hand. With the tree tip, you can sort of turn it back and forth as you insert the plug into your ear. You want to twist and turn the plug into your ear until you feel you have snug and secure fit. Once you feel that, you should be good to go.
The tree tip ear plug definitely provided a tighter and more secure waterproof seal into my ear. In the 30 to 40 minutes of my swim workout, one of the plugs came out once, and it was easily re-inserted. Sound quality and overall comfort and effectiveness of the entire H2O Audio Interval was still excellent, and still making a positive impact on my swim workouts!
I would recommend getting the H2O Audio Pro Fit Kit if you plan to use the H2O Audio Interval, and you could also consider the kit for any other use of headphones underwater. For example, H2O Audio has the Audio Amphibx Waterproof Armband Case and the Audio Amphibx Go Soft Case as well as at least 5 different styles of waterproof headphones to accompany those cases.
I may try out the memory foam plugs next, and if so, I’ll be providing an update.
