audio Black+Red Silicone Eartips Kit with Case and Nozzle Adapter for 1More, AKG, AT, Beats, Campfire, Empire Ears, Shure, Sony, Westone

I have Sony WF-1000XM4 in-ear Headphones, which sound amazing. Especially if you experiment with the equaliser and use LDAC. However, I couldn't always get an airtight fit with the supplied ear tips. Sony's app allows you to test the fit, and it would take two or three tries to get the headphones fitted correctly. I saw a video that mentioned these tips, and since having them, I no longer need to use the app as I get an airtight fit every time. They also enhanced the sound. I no longer use my wired headphones. With the Sony WF-1000XM4 in-ear Headphones, these tips are a match made in heaven.

Comfortable and stays in ear really well. The material has grip yet is extremely smooth and the seam is essentially nonexistent.

I've been through so many eartips and struggled to find the one that matched my ear canal. My left ear canal is much narrower than my right. I've been through spinfits, jvc spiral dots, sony hybrids, azla sednaearfit xelastec, etc. These bring the mids and sub bass out with just the right balance for my 64audio U8 paired with Calyx M

I use these in all of my 10 sets of iems.
