I didn’t realize Symbio now makes tips for APP (previously, you had to buy their tips, remove the foam from their silicone tip and put it into the APP silicone - a process described earlier in this thread). Anyone know whether in their complete solution the silicone is bonded to the foam?
I just got the Symbio for AirPods Pro today. The silicone is not bonded to the foam, which is probably a good thing. In the package I got, the placement of the foam was different on each tip. It honestly looks somewhat like they performed the same process of applying the foam to the OEM tips. I wound up turning the silicone inside out and readjusting the foam on the two I used.
So far I'm
mostly happy with these tips. They fit perfectly in the case (used the Medium tips), so no problem there. The sound is great with ANC and with Transparency. I did a 12 mile workout with them in, both walking and running, and never had to readjust, never felt like they were falling out.
That's a massive improvement over the Apple's APP ear tips. While the OEM tips are generally pretty secure in my ears while walking (unless I'm really sweaty), they tend to come loose and sometimes fall out while running without constantly pressing them back in, particularly the right ear, regardless of which size I've tried. There was none of that with the Symbio tips.
What I
didn't like is that I took the Symbio tips off and applied them again several times, because there doesn't seem to be an audible "click" when they snap securely to the AirPod like Apple's tips do. If there is, it's far more subtle than Apple's. I got them secured enough that they wouldn't come off with a decent tug and called it good. When I completed the workout, I took out the AirPods, and one of the tips stayed in my ear. I had to fish it out. Not at all fun. If that happens again, I'll probably switch back to Apple's tips and mod those with the foam from these.
