I had the Truecapsules (https://www.amazon.ca/gp/product/B07S17VPPZ) for about a month. For music, sound was pretty good for my standards, but for calls, people on the other end said it sounded very echo-y. The multiplefunction button was a sensor area and was not bad but then again i was also not expecting much for $40ish. You stop and play songs, pick up and hang up calls, and you can change songs forward and back. Then after 3 weeks time, the left ear was in constant pairing mode so i returned to Amazon.
In search of another pair of true wireless earbuds, I bought the Truengines (https://www.amazon.ca/gp/product/B07QB22QZS). For music, sound was just as good if not better than the truecapsules. For calls, people couldn't differentiate if i was using the Soundpeats or if i was speaking directly into my phone so that was a huge plus for me. The multi-function button is actually a button that you can click. You stop and play songs, pick up and hang up calls, and you can change songs forward and back, but these earbuds also had the ability to change volume up and down (double click). It was good at first, but after about 5 days of use, the button's ability to click stopped. However, it still works to stop/play, and pick up/hang up calls, and since I got these at a huge discount, i'm planning to keep these for a bit or close to the end of its warranty.. which is 12months.
Both pairs provide little silicone rubber thingys in different sizes as do majority of bluetooth earbuds. However, I notice when you walk with those and your music is not loud enough, you can hear your steps. I have some leftover memoryfoam ones from my jaybirds and after swapping the silicone ones with these, they make the fit and sound a lot better.
Very interested to see what the Truengine2s are like, but I will definitely wait for the price to drop.
