I sat on the plane reading this book. These shoes are very helpful in that area. Very disappointed and very very small. His plastic mold is very good, without burr. It does a really great job in this core role. Decent bass and volume and I would agree with other reviews that say it excels in the vocals. I?d order 1/2 size smaller and see how you do. Turns out, it had a much bigger built in powerbank than I was expecting. It lasts me a couple of days before I have to charge them (I usually use them for the gym and at night when I watch Netflix on my phone. But with that being said, I do like them.
