Etymotic ER3XR Extended Response Sound-Isolating Earphones

Superior Sound for Mobile Music + Bass Boost Etymotic ER3XR Extended Response provides studio-quality audio with a small bass boost. These earphones are specifically designed for listening to mobile sound sources such as smart phones, tablets, and handheld music players. What sets the ER3XR apart from the other noise-isolating earphones out there is its incredibly high sensitivity. With 102 dB SPL sensitivity at 1 kHz at 0.1 mV, these earphones capture the best audio output your sound sources can provide, delivering full, clear, robust sound right into your ears. The result is an earphone that blocks outside noise and provides professional-quality sound, all tailored to work with your smart phone or music player. The bass boost on these ER3XR earphones is just right - not too little, but not too much. The ER3XR delivers a modestly enhanced low end that doesn't stray too far from professional studio quality, but that carries just enough kick to satisfy your craving for more bass. The noise isolation of the ER3XR combines beautifully with the extended bass, enhancing the low end without accidentally overwhelming the other frequencies. The earphone bodies are precision machined and feature a sleek and stylish anodized finish, so they look just as good as they sound. The 4' cable is perfect for relaxed wear on the go, and the standard 3.5mm jack fits virtually all smart phones, music players, tablets, and other sound sources. Best in Class Noise Isolation Etymotic's noise-isolating earphones block outside sound from entering your ear while you listen to music or other streaming audio. This is thanks to the included isolation eartips - the tips that fit inside your ears. The Etymotic ER3 series offers some of the very best noise isolation available today from any earphone anywhere, with 35 - 42 dB of noise isolation. That much isolation means external noise can't intrude past the eartips, so the sound quality of the audio that reaches your ears is pristine, rich, and faithful. With noise-isolating headphones or earphones, you can enjoy dynamic highs and lows in all their detailed glory - even with your sound source turned down to a lower volume than normal. For those who listen to music or other streaming audio during a noisy commute, and who crave a little extra bass, the ER3XR is virtually the perfect earphone. And it costs significantly less than other earphones with comparable performance. What's in the Box
