New York, NY (Top40 Charts) Etymotic Research will demonstrate updates to its classic ER4� insert earphones, the new ER4SR Studio Reference earphone and ER4XR Extended Response model, at the 13th annual Rocky Mountain Audio Fest in Denver, CO on October 7-9th. The Etymotic booth will be in the CANJAM room. The show is billed as "the largest consumer audio and home entertainment show in the United States."
For more than two decades, the ER-4S has been the world's most accurate high fidelity, noise-isolating earphone. Because of this, and its 30-40 dB noise isolation, the ER-4S has remained largely unchanged until now. The new models meet three design goals: 1) to provide greater accuracy in sound reproduction in the ER4SR Studio Reference earphone, 2) to offer consumers a choice with the ER4XR Extended Response option that delivers a little more bass without sacrificing the overall quality of the listening experience, and 3) a durable cable that is user replaceable.
The ER4SR Studio Reference earphone improves the accuracy of the previous ER-4S model, while providing a significant improvement in sensitivity, making it more compatible with the portable media players on the market today. The ER4SR offers audio professionals and those wanting the ultimate in sound accuracy a new level of performance.
The ER4XR Extended Response earphone offers a modest bass boost, building on the original ER-4's neutral sound, while providing a sound signature that some ER-4 fans have been asking for.
"Etymotic invented the noise-excluding in-ear earphone, giving consumers an unparalleled listening experience with noise isolation superior to other in-ears as well as headphones with 'active noise-cancellation' options," says Etymotic VP of Sales and Marketing Al Arends. "For 25 years, the state-of-the-art insert earphone has been the ER-4. Now, with the arrival of the ER4SR and ER4XR, the world's most accurate earphone just got better. Then or now, we have found no multiple-driver design that can match the accuracy of the ER4."
Priced at $349, both models feature precision-machined, anodized metal bodies and Etymotic's industry-leading 1-dB match between left and right channels across frequency with individual channel-matching performance charts provided with each pair of earphones. For more, go to etymotic.com.
