5 dB Q 0. Due to other reviews, I decided to size down. So comfy and cute looking! One thing I really like about this brand is that their sandals are orthotic and stylish. The silcone gels fit without any problem, but doesnt really help with blocking out the noise. I almost felt a nostalgic, "I better read about it now before everybody forgets" draw to the book. The shoe fits about as expected; slightly large. I was able to walk and drive with no issues. I have several sets of wireless earbuds, everything from expensive Galaxy Buds Pro and Airpods on down to very affordable ones such as this pair. La calidad del sonido es impresionante y además mis amigos mencionan que me escuchan más nítido y claro.
