I've had this in my Amazon shopping list for a while as I've read some good reviews about them.
I currently have a pair of Shure SE215 and I thought they were pretty good - I bought my first pair back in 2009 and to my untrained ears they sounded great for the price I paid. Bought a replacement pair of SE215s last year and although my ears are still untrained, I thought it didn't sound so good even when I just used it on an old iPod.
I'm definitely no audiophile, I don't have specialised audio equipment, and I don't want to take up that hobby; but I do want a pair of IEMs that is not super expensive but worth the money you pay for. And according to this page (https://crinacle.com/rankings/iems/), the 7Hz Timeless should be pretty good for the money.
Regularly cheaper. Then there's cashback as well.
Continue your research and you'll find there's even better options starting to pop up in that price range.
Next year there will be a flood of xMEMS Cypress TWS IEMs competing at this price too, which will offer phenomenal resolution and ANC.
