Mp4nation.net is running a promotion on their flagship dual dynamic earphone – the R3. Normally $130, the R3 (version 2) can temporarily be had for $89.50 including shipping (via FedEx 2-day for some countries) with a free Brainwavz AP001 dual-output headphone amp (normally $29.50). For more info on the AP001 see the product page here and the Head-Fi topic here.
At this price the R3 is a great earphone – it delivers a very smooth and balanced, slightly warm sound with good dynamics. I was also impressed by the heavy-duty construction and surprising lack of cable noise. The fit can be a little tricky, but the latest version forgoes the memory wire, making the earphones easier to wear. My full review of the R3 can be found here: Brainwavz R3 v.2 review
