生产商提供信息
Etymotic Research, Inc. is an engineering-driven research, development and manufacturing company. The name 'Etymotic' (pronounced 'et-im-oh-tik') means 'true to the ear'. Innovation, education and hearing conservation are central to Etymotic's mission.
ER4SR Studio Reference
The World's Most Accurate Earphones Just Got Better!
Over 30 years ago, Etymotic invented noise-isolating, in-ear earphones. Etymotic's original design, developed for auditory research and hearing testing, used balanced-armature receivers and established these speakers as the gold standard for high-definition, in-ear earphones.
- Detachable 5 foot cable
- High performance balanced-armature drivers
- Sleek driver bodies with anodized finish
- Braided cables for reduced microphonic effect
Why Etymotic?
Why ER4SR Studio Reference?
Etymotic designs products to measure, improve and protect hearing, and enhance the listening experience of music lovers everywhere. Audio engineers, musicians and audiologists at Etymotic have generated over 100 patents issued and pending.

The ER4SR is a must have for discerning engineers, audiophiles, and consumers wanting the most accurate in-ear earphone available.

User Detachable CablesTo detach the cables, pull the cable connector away from the earphone body. Pull straight out-Do Not Twist. To attach the cables, align the key tab on the cable connector with the notch in the body of the earphone. Press together until it snaps in place. |
Changing the FiltersEtymotic earphones have special filters that smooth the frequency response and prevent earwax from entering the earphones. The filters are located at the end of the earphone and are visible when the eartip is removed. When a filter becomes clogged it should be replaced. Filters should be changed when output decreases or sound quality declines. |

对不起价格
在 2022年2月13日由 易安
这耳机佩戴不是一般的难受，只有海绵套稍好些，海绵套耐久性不佳，使用月余感觉弹性变差，效果也差了些。包装中一共有两幅海绵套，另一副有制造缺陷。视频收货，反馈到亚马逊客服做出了应对，此处省略。音质方面解析度确实不错，人声靠前，低音就别要求太多。但代价是深入耳道，舒适度非常不佳换来的，很是不值。三节套对隔绝外部声音帮助不大，外出不合适，在家还是大耳，这货也没比JBL club one强。用了十多天突然想起看签名的鉴定，一看一肚子火，居然失真率双双高达1.1以上，对这个价位的高保真耳机着实说不过去。没吹捧的那么好，佩戴舒适度差。不建议购买。
