Headfonics's MarcusD serves up a well-organised review of Westone's new W50.
Westone: Seven Ways In-Ear Headphones Can Help Advance Your Career
Admittedly, in-ear earphones drip a level of professionalism that over-the-ear headphones simply can't. But certainly they do not do so in every office or work situation. Outside of a few, special cases, I call BS on this Westone article. Listening to earphones can focus you. There is no doubt of that. But they also tend to focus you like blinders do a horse, and not always in the way your boss/customer intends.
Enjoy your Bieber, but I'd check with your boss and co-workers before closing the world off with a great set of Westone or Jerry Harvey, or FitEar earphones. And for the love of god, stave off the desire to put anything Beats in your ears.
headfi: Westone AC20 musician's review
Headfier and admitted basshead, RiKToR, got all up into that custom IEM thing, having his church foot the bill for the Westone AC20. His impressions are frank and well-organised from a musician's, not an audiophile's perspective.
Thank you again, headfi.
