Logitech has a tasty offer going on a high quality set of earphones. The Ultimate Ears SuperFi 4 is on sale $49 at Logitech but if you use the coupon code from DealNews — superfi4_311 — it drops the price down to $29.99. Plus there’s free shipping. Nice, eh? Now, the reviews on Amazon, where the set retailers for around $50, aren’t all stellar. They’re only rated at two and half stars with 90 reviews so your millage my vary.
