Put in the ER2XR drivers and drop it to 150 and I would definitely buy them.

er2xr is underrated. throw in brown filters and it's very closer to er4sr with better bass.

The irony of having one of the promotional pictures next to a iPhone when these have a 3.5mm jack kinda kills me.

Hey everyone! Etymotic has been hard at work to release a new collab IEM with us, the ERX In-Ear Monitors. These combine two aspects of some of their most popular products - the ER4 sound profile in their EVO shells - making for a more comfortable listening experience. We hope you enjoy them as much as we do! Please post any questions below and I'll do my best to answer. :) Reviews from external sources are in process and will be linked here once complete.

It would be nice to include what kind of measurement rig was used written on the graph too. B&K, GRAS, etc. (I'm assuming it was the GRAC 43AC or IEC60318-4 equivalent?)

Mangird Tea as well. Very nice sounding IEM that fits amazingly well in most ears.

bjvp182The EVO shell still goes in pretty deep IMO. The new shell is a lot more secure and comfortable despite the deep insertion though.

Where to start? Well, first, I will say that I have tried almost every Etymotic IEM since the ER4S - ER4S, HF5, ER2XR, ER2SR, ER3SE, ER3XR, ER4SR, ER4XR, EVO... Needless to say, I'm very familiar with the Etymotic tuning and form factor. So I'll be honest, I wasn't ecstatic about the idea of a possible re-shelled ER4XR (one of my favorite Etys). Bigger perhaps? But why? Any good reason? Let me start by saying that I'm a fan of the Ety original barrel housing design as well. However, the ERX has brought two new improvements I wasn't expecting. First, the shell is more semi-custom ear-shaped (like EVO) and actually feels more stable in my ear. No real movement. The older barrel design can be torqued somewhat no matter how deep and could cause discomfort. Second, they have included a new tip design I haven't seen before. It is reminiscent of the Shure star tips if I'm remembering correctly. However, they are molded to fit the Ety barrel nozzle and are long enough to allow full insertion. The most amazing part (for me at least) is that they are SO much easier to insert fully, acquire a seal, and not cause discomfort. I'm actually very pleasantly surprised. This is the single biggest improvement in the new model. I think this could literally appeal to listeners that otherwise would shy away due to discomfort issues. There is still a sense of pressure and deep fitment, and new users should give some time to adapt to a deep fit IEM, but it is vastly improved in my opinion. So what about the sound? Well, like most Etymotic IEMs, the general tuning is very "Etymotic" in nature. Also like most Ety IEMS, it doesn't vary too drastically from other models. The ERX seems to align most with the ER4XR tuning with a slightly more laid back treble. The sound so far to my ears is smooth and clean and relaxed, while still maintaining Etymotic's superb neutrality overall. I'll have to give them more time to solidify my opinion of the sound, but take a look at some graphs: Keep in mind the resonance peak around 10k will shift depending on insertion depth.

With the resonance peaks aligned, you can see the treble is more laid back in the lower area compared to the ER4XR. This isn't as objectionable as I would expect when listening, in fact it reminds me of the difference between the HD600 and the HD650 if you've heard those. It's just a more relaxed slope without losing too much of the classic Ety treble shape.

Compared to the original ER4S you can see the similar bass boost in as the XR model and the more laid back treble as well.

Regarding other aspects of the sound, I'll compare more before doing a video review, but I feel like the treble is cleaner than the ER4XR, but I'm not completely sure yet if it's simply the response or not. It has a liquid smooth treble. I feel like it's right at home with the ER4 line of IEMs overall. The technical performance seems very good. Stereo width is good for an Etymotic. They are relatively easy to drive as well. One thing to note is that adding impedance to the cable does create a very slight upward tilt in the treble. This is measured with the Etymotic 75ohm adapter added:

It's nothing major, but does add just a touch of openness to the sound. It does make them noticeably harder to drive, but with a decent amp and a 100ohm adapter or more it might give some people a bit more of the classic treble curve while keeping the new form factor. That will probably be a very personal preference, but it's nice there is even a slight possibility of tweaking the response. So what are my thoughts on the ERX? I'm actually pleasantly surprised overall. The new tips are absolutely worth trying. The form factor wears nicely. While many people vary on their cable preferences, I am a fan of the sold sheath rubber design of the included cable. Small cable split section. Cord cinch built in. Wraps very compactly. It has a slight elasticity to it (it resists being wound somewhat) but I've seen worse. Overall, it seems like a decent cable. I would have preferred MMCX, but at least it's replaceable if needed. The included case is also something I'm a huge fan of. Historically, Ety has included small pouches and large cases, but nothing in between. I like the pouches for pocket sized carry, but they aren't very protective. The cases are moreso, but overtly large. This comes with an excellent molded pill shaped case that is semi hard and has a small pocket inside and a nice quality zipper from what I can tell. So fairly pocket-able and just a good small size with good protection. There is also a filter removal tool and a set of spare filters. The included eartips are essentially one of each tip and size. No typical foam tips are included, which is a bummer for anyone trying out tips, but the inclusion of the new long silicon tips is very welcome. So the accessories are pretty basic but nice. It's one of the more minimal but well made packages of accessories IMO. For returning Etymotic customers, if you don't have an ER4 yet, this could be a great entry into the model series. If you like Etymotic but want a slightly more laid back ER4, this fits the bill nicely. The build feels excellent and tough, the cable is replaceable, the tips are the most comfortable to date for Etymotic, and the sound is what you'd expect from them - neutral and revealing. Stay tuned for a more in depth video review, but for now I would say I would definitely recommend these for the price. There are many Etymotic models now, and choice can be a pain. However, this does sit well in the ER4 territory. As such, the price seems reasonable. If they could lower it more permanently to $250 or even $200, I think that would seat this as an extremely attractive option for a wide audience. I look forward to spending a lot more time with them in the coming days...

Heck yes, big respect for etymotic as a whole. The story for this product indicates er4 sound in an evo shell, so looks like it will be an interesting balance to strike. I do not have firsthand experience with evo insertion depth and how it affects the sound compared to the triple flange stick, so it will be curious to see. Hoping the product comes with specially tuned nozzle filters made by Drop to add an option for a unique exclusive sound profile.

Same. I still have my ER4P with the S adapter for desktop use. Sadly the XR response profile doesn't really interest me.

J--WI'll never sell me er4s. it is the pinnacle of etymotic. wish it had more low bass at times, but man it sounds good on a good setup. it's just not as ideal for mobile amps as it is such a high impedance set... so these new models are great for being easier to drive for sure...

These are so close to being extremely appealing. They need to use MMCX connectors and they need to be $100 cheaper. At $299 (the retail price after the 300 pre-orders are sold), you are talking Blessing 2 money. Are they going to be better than B2s? I look forward to finding out when reviews start coming. At $200 these would probably redefine the price bracket. Will watch this closely, but am thinking these are probably not a buy unless the price comes down or something really unexpected happens.

Yeah I don't like any of them for frequent switching, they will all wear out. But I do like cable choices, especially since I dislike a lot of pre-formed earhooks.

HewbaccaOwning the B2s and the older ER4 it's a draw. The B2 may be more fun but the ER4 is by far more accurate. Both of them punch well above their price point. You're comparing two titans in this price range.
