I have been extremely pleased with Brainwavz S1 headphones. I have not been very impressed with any of the in-ear headphones I have tried in the past due to lack of comfort and poor sound quality. Brainwavzs has a developed a product that has addressed these areas and offers more.Firstly, the ear buds fit comfortably and don't tug on the ears. After an hour of wearing these headphones, my ears still feel fine.  The company includes several different options for inner ear tips. It is trial and error to find the ones that work for you. Secondly, the sound quality is great for my uses. I tried these on an airplane to watch a movie and during a work out to listen to music. As advertised, the bass and vocals were clear and not overbearing. Though they didn't cancel sound as the bulkier headphones do, but the sounds quality was impressive while on the airplane. To note, I did not try any tips other than the tri-flange tips during the plane trip. Additionally, when the outside of the earbuds are rubbed or brush against something during sound play, the sound is not impacted.Some added features that add to this product are the flat wires that cut back on tangling. This seems to work well. They did not require any untangling when getting them out for use. The hard earphone carrying case is great and small.Overall, this is an excellent product. They offer excellent sounds quality in a compact size and an affordable price. I recommend these for anyone searching for good quality ear buds.
