An earphone's price is not highly correlated with the quality of the earphone, which comes down to components and quality assurance. Rather, earphones prices are heavily affected by brand positioning, and the fact that there’s usually a large number of middlemen taking a cut along the way. 

You can find $500 earphones that have the same quality level as $250 earphones, and $250 earphones that are made of very poor quality materials. You really need to look below the surface to get good value for money.

We spent two years developing the E70 Pro because every little detail matters. And partly because we're a bit insane.

Professional engineers, musicians, designers, and people who’ve never even had wireless earphones before have hand tested and refined our earbuds every step of the way. We painstakingly tested 37 prototypes to find the perfect pair of earphones.

The final result? A crisp sounding earphone that’s comfortable to wear, loud enough to drown out your neighbors lawn mower, pairs like a charm, and lasts as long as you do. You’ll love it as much as we do.

The devil is in the details!

At every step along the way, our earphones were hand tested and refined by professional engineers, established musicians, product designers, and people who’ve never even had wireless earphones before. We painstakingly went through 37 different prototypes until we knew we had the perfect pair of earphones.

The devil is in the details! Examine the watch carefully for others signs of cut corners in materials and workmanship. Here are a few details that betray a watch that hasn't been made with high quality standards:

- Plastic spacers between the glass and the dial

- Uneven brushing (if the watch has a brushed finish)

- Unexpectedly light in weight (it could mean that they've skimped on materials)
