Review: Steal for the price in the IEM market - Don't be afraid of picking in between 4SR because it's "Studio Reference". These have great bass and is definitely there on all songs. It's a very clean quick punch bass that has is well defined (unlike the lower end IEMs in which all bass sound the same, the bass here has octaves). Instrument separation is a given as the detailing is phenomenal. Better than even thousand dollar IEMs like Shure SE846 in terms of sound quality. This is Etymotic's flagship model. The ER4 SR. The most accurate diffused neutral tuned IEM (outside electrostatics). Prepare to hear music like water. Clean and detailed. The "ear drilling" might take some people some time to get used to (for me, it was fine right away but I recall when I was younger, the "ear drilling" on the ER4P was definitely too uncomfortable for my taste). It's obvious the pros are as follows: 1. Sound quality. Sound quality. Sound quality. If you want to step up from here, you will have to spend thousands+ on IEMs and even then it's debatable. This is probably the best sound quality you can get out of an IEM under a $1000 in today's market. I hear good things about U12t, Andromeda, etc. but those are so far up the price point that it shows how great this IEM is sound quality wise. 2. Noise isolating. Cause it drills to your ears. 3. You will hear all the details in the piece because it is balanced in a diffused field manner (all frequencies should be able to be heard). The cons though to be aware of: 1. Cable is too long (1 ft longer than others). And the braided part (top) has quite a lot of microphonics which can be pain in the neck if you wear winter jackets. You will need to use the clipper that comes with the IEM in between your jackets when wearing winter jackets or otherwise, your earphone on your ears will feel heavy. 2. If you find drilling to your ears uncomfortable, well.. you should look elsewhere cause comfort matters. 3. If you have a girlfriend or a significant other, it's probably better going for another IEM as this IEM is really hard to share with others. No one wants to touch products that were already drilled into someone else's nasty ears and it's just difficult in general to share 1 plug to another with this type of drilling. 4. Sound stage and imaging can be 2-dimensional. This is what really separates the $thousands+ IEM from here. Not detailing. More of imaging and sound stage. This IEM has a soundstage of in between your two ears (aka head). Don't expect more. 5. If you want the best bass quality, opt for bassy IEM like Shure SE846. The "rumbles" don't exist with this IEM. Other than that, I wholeheartedly recommend Etymotic ER4SR at any price range under $1,000. And if you can't afford it, Etymotic ER2SE.
Review: Etymotics - now with replaceable cords!! - Etymotic makes some of the best earbuds in the market. The great thing about them is they fit tight in your ear and, to me, work far better than any noise cancelling earphones I've seen. At the same time, no one can hear what you're listening to, and since the sound is so good, you can keep the volume lower so as not to damage your ears. I've owned Etymotic's for a good 10 years. The company has been fantastic to me, always replacing the cords free of charge when they break (and after owning a pair for nearly two years and brining back and forth to work in a bag, eventually they get a short). I bought the ER4SR, just released, because for the first time you can buy replacement cords for these. What an awesome idea! Even better, I haven't seen confirmation of this, but I'm fairly confident they'll offer an iPhone lightening connector version as an accessory (they'll have to with Apple's recent stupid move to get rid of the earphone hole). These earbuds are quite pricy to be sure, but they're worth it, whether you're an "audiophile" or just an average music listener, you'll feel like you're hearing your music for the first time. I cannot recommend Etymotic's enough. Highest quality, best sound, best noise reducing (pretty much passive cancelling, like ear plugs), and brand you can buy.

## Questions & Answers

**Q: How does the er4sr compare to the older er4s / er4p?**
A: While both the HF and ER4 series use a balanced armature driver, the ER4S is precision matched to within 1 dB. Performance certificate is included with the ER4 series.The new ER4SR uses the same high performance drivers as the original ER4S. Both are designed to produce the most accurate sound reproduction possible. They are often used by studio recording engineers (S is for Studio Reference). The original ER4P and ER4P-T were designed for audio engineers and audiophiles on the go (P is for portable). They are tuned to maximize sound from portable music players. The new ER4SR will give you the sound accuracy you expect from the original ER4S or P with the added benefit of removable cables. If you prefer a little more in the lower frequencies, go for the ER4XR--Extended Range.Please feel to reach out to our customer service department at 888-389-6684 if you have further questions.Etymotic Research

**Q: Are these flat/true for mixing on the go? If not which ones?**
A: These earbuds are true and great for iPod iPhone use. Good highs and mids but a little tinty in the bass end. Nice tight buds if you use the ety cones that are supplied. Also they are number one in noise reduction!! Work or play they won’t fall out. 8 of 10!

**Q: What is the difference between this xr and the sr version?  thanks all!**
A: Thanks very much for your question. The  XR has a modest bass boost and the SR are completely flat. World Wide Stereo is 39 years old and a proud authorized Etymotic Research dealer.

**Q: Do the headphones sold through amazon warehouse deals still come with the etymotic research warranty?**
A: No. WiredforLess is correct. Only NEW purchases made from an AUTHORIZED Etymotic reseller will be eligible for warranty coverage. Amazon itself is NOT an authorized reseller and warehouse deals fall under used product.Not all sellers currently operating on Amazon or other online sites are authorized. If you are not certain whether or not a reseller is authorized, you are advised to first call Etymotic's Customer Service line at 888-389-6684.Etymotic Research

### ⭐ PRODUCT FAILS AFTER 2 YEARS!
*by T***L on October 30, 2020*

Absolutely love the sound quality of these earphones, but can't afford to keep replacing when they fail. This our families 4th pair! (my son received a pair which failed, then replaced which also failed, I am now on my second pair and they have fortunately failed inside the two year warranty window so at least etymotic has to replace this pair for free). Same issue, over time one or both of the speaker drivers become distorted, slowly reduce output, and then blow. Very frustrating as the sound quality is outstanding. Four pairs that have failed over multiple years, however, do not lie.
