I received the Tin T3+ yesterday.
I opened their box, and the earpieces looked fantastic. Probably one of the most handsome IEMs I have ever purchased.
However, to my horror, I struggled to get a good and consistent seal and they were hurting my ears. I eventually gave up and put them away with the intention of returning them. I had some serious buyers remorse, and was cursing those reviewers who had hyped this set up.
This morning, I decided to give them one more try. I stuck Spinfits on them, and lifted the top of my ear while inserting them. Lifting my ear had never been necessary with my other IEMs, as they all went in easily. However, the T3+ were suddenly comfortable, and stayed in place.
I have listened to some albums by Bjork, Metallica and Morrissey while using these IEMs, and am enjoying them a lot.
The moral of the story? Do not be hasty to judge a set of IEMs.
