These are my first pair of EarBuds. I did quite a bit of research before buying these ear buds. I looked over different features, their pros and cons and their usability for me. These earbuds stands out and I bought them. Though there were other option with slightly cheaper models but I am completely happy with my purchase. I have been using this earbuds since I got this. There are 3 thing I care about any headphone1) Sound Quality2) Comfort for Extended use3) Noise Cancelling CapabilityI would rate the sound quality to top level. There no sound distortion, the bass is good and not much treble. The sound quality is does not fade away ever in higher volume level. I would put the sound quality similar to some higher end (established brands) headphones or earbudsThe earbuds perfectly fits in ear. I have been using them and simultaneously doing my daily routing like cooking, Gym, driving and other, it did not fell off and I did not felt any uncomfortable using these for long period. In addition, they provide different size of earbuds with package.I was surprised with the noise cancelling capabilities of these earbuds. As instructed in the User Manual, one needs to find the perfect size of earbuds to experience the best noise cancelling feature.Overall, there earbuds are perfect and worth every penny. They are really handy to use. The product comes with a easy to follow User Manual. The function like play, pause, next ,volume control are easy and earbuds are super responsive to such command. I highly recommend this product and Happy to answer any question regarding the product.
