Westone isn't exactly a household name, even in the earphone universe. But what the company lacks in recognition, it more than makes up for in quality. If you'll recall, we had a listen to its ES5 custom in-ear monitors earlier in the year, and while they cost a staggering $950, they also managed to melt our brain and thoroughly spoil us in the process. Thankfully, there's a budget alternative: the Westone 4. Granted, even 50 percent off still lands you right around $449, but many audiophiles would argue that said price is a small one to pay when looking at a quad-driver setup, a three-way crossover network and an insanely robust set of earbud tips. There's no question that these guys are aimed at the professionals in the crowd, and if you're interested in seriously stepping up your mobile listening game, you owe it to yourself to peek our full review. It's after the break, per usual.
