Upon opening the box these earbuds look very stylish and feel like an expensive and well made product. After a short charge I connected them my phone seamlessly and head out for a run. Straight away, the sound quality is amazing; full basslines, detailed highs and just the right amount of mids. The earbuds stay in comfortably without any problems for the duration of my run (40mins). Having used the earbuds for a week now, I can confirm the battery life is great, the product has fulfilled all its promises and has surpassed all my expectations. Would recommend to anyone interested in a high quality pair of earbuds for a reasonable price.
