Review on Enhance Your Music Experience: 12 Premium Memory Foam Ear Tips for Powerbeats 2 and Most 5-6.3mm In-Ear Earphones - Noise Reduction, Dustproof, and Long Lasting by Keize Barraza

Used them for 2 hours at the gym yesterday so far it's a complete experience but perfectly comfortable for 2 hours on an elliptical. I have Bluetooth headphones, no active noise cancellation. Loud gym, background music, bike zone where leaders use microphones flying out of the bike zone, cinema zone where they turn on movies at 15 volume out of a 10 scale, people yell their way from all over the gym and upstairs to lower level and so on. With the original device's standard flexible white headphones, you had to keep the volume near the top of the headphone range. Now, with these, it's probably a 30-40% reduction in volume to hear what I'm playing. Noise-cancellation is like wearing soft rubber earbuds for musicians (and shooters). Of course, there is no need to talk about durability. I didn't feel any pressure on my eardrum or pressure on my temporomandibular joint or anything like that. I hope they are long lasting, I can't talk about that. Mine was the biggest. Maybe I just have big ear canals to make up for my other shortcomings.
