Etymotic Research ER2XR

The ER2XR is a wired IEM with killer isolation and accurate sound, but skip it if you need wireless or comfort. At $100, it's a steal for critical listening.

The sound is where this thing shines. The dynamic driver delivers a frequency response that's remarkably flat from 20Hz to 16kHz, with a subtle bass boost that doesn't muddy the mids. I was surprised by how much detail comes through at moderate volumes, thanks to the 42dB of noise isolation. You don't need to crank it to hear the double bass or the breath of a vocalist. The 15Ω impedance means it's easy to drive from a phone or laptop, though a dedicated DAC will tighten things up. But here's the catch: the isolation is so good that you'll hear your own heartbeat and footsteps. And the cable, while detachable, is thin and tangles easily. The mic is genuinely bad, so don't plan on taking calls with these.

The obvious comparison is with the Etymotic ER2SE, which is the neutral version without the bass boost. If you want pure accuracy for monitoring, the SE is better. But for casual listening, the XR's extra low-end makes it more enjoyable. Against wireless options like the Sony WF-1000XM6 or Bose QuietComfort Ultra, the ER2XR wins on pure sound fidelity and isolation, but loses on convenience, features, and comfort. The Samsung Galaxy Buds3 Pro and Apple AirPods Pro 3 are better for everyday use, but they can't touch the ER2XR's clarity. If you're deciding between wired and wireless, ask yourself: do I need to move around? If yes, go wireless. If you're sitting still and listening, the ER2XR is the better choice.

At the typical street price of around $100, the ER2XR is an absolute steal. You're getting studio-grade isolation and sound that rivals IEMs three times the price. But watch out: some vendors are listing these for $2,962, which is pure insanity. Stick to reputable sellers and you'll get a fantastic deal. If you're paying more than $150, you're overpaying. For the money, this is one of the best wired IEMs you can buy, period.

The Etymotic ER2XR is a wired in-ear monitor that does one thing exceptionally well: it isolates you from the world and delivers sound with surgical precision. If you're a critical listener, a musician, or someone who just wants to hear every detail in their music without cranking the volume, this is a serious contender. But let's be clear: this is not a wireless earbud, and it won't compete with the AirPods of the world. It's a niche tool, and it's brilliant at what it does. The ER2XR is the 'extended response' version, meaning it adds a bit of bass punch to Etymotic's famously neutral tuning. That makes it more fun for everyday listening while keeping the clarity that made the brand famous. Just know that the deep insertion fit isn't for everyone, and the mic is an afterthought.

If you're looking for wireless earbuds with ANC, a good mic, and a comfortable fit for all-day wear, this isn't it. Go get the Sony WF-1000XM6 or Apple AirPods Pro 3 instead. Also, if you hate things in your ear canal, the deep insertion will be a dealbreaker. The ER2XR is for people who prioritize sound quality and isolation above all else.

Buy the ER2XR if you're a serious listener who values accuracy and isolation over convenience. It's a wired IEM that does its job flawlessly, and at the right price, it's a no-brainer. But if you need wireless, a good mic, or a comfortable fit for all-day wear, look elsewhere. This is a tool for focused listening, not a lifestyle accessory.
