Twister6 posted a review of the HiFiMan’s RE2000 IEM over on Head-Fi. It is a single dynamic driver IEM priced at a flagship TOTL price ($2,000). From the reviews it seems to compare well with IEMs priced in the $1,500 range. While I do own some of the IEMs in this price range I would recommend steering clear of the IEMs over $1,000. Unless weight and size are critical to you such as when my job required 100% travel, I would recommend purchasing a great pair of headphones and DAC/amp.
Pros – detailed hi-res sound, excellent bass response, wide soundstage, unique topology diaphragm tech, removable cable.
Cons – price, ergonomics of the design, eartip selection.
