This is a good and perfect replacement for original memory foam ear buds which comes along with the earbuds. I am using SONY WF-1000XM4. After 30 mins of continuous listening the memory foam buds creates some pain. This silicone buds are of good comfort. Tried upto 2 hours of listening and no pains. Note - There will be compromises in ANC & bass levels.

Personally i find these buds are quite expensive for the quality and overall product. Wanted to try these ones, these one are quite bright(increases treble at the expense of the bass). Quite comfortable though but i still prefer foam ones with warm sound and punchy sub bass.

It works like a charm on my Jabra Elite 85t. I was stuck with an expensive pair of Earbuds, which didn't fit properly due to my oversized ears. Someone suggested I try the Spinfit 360s and yes, they did work to a large extent. I get a slightly better fit, and even the noise cancellation is decent. Buy them, if you think the OEM ear-tips aren't working for you.
The shopping experience on the site is smooth, and the shipping is prompt and clean.

Using with Jabra Elite 75t and the grip and comfort are good.
