Got these a few months back, and now having time to adjust to them and experience them properly I present my review of them.

The headphones are well packaged, they come in a sturdy plastic case, which houses the phones and the various accessories. This in turn is provided inside a cardboard outer box. Pretty standard, but well packaged.

In the box are the earphones themselves, along with a cable clip, headphone adapter, assorted ear tips and filters and the tool to interchange them; manual, response accuracy chart and soft carry pouch. In other words, a lot of accessories for earphones!

Out of the box, the ER4's come with the small flange ear-tips attatched. These are easily changed to whatever type you want by simply pulling them gently from the headphones and pushing a new pair on. I did a bunch of testing with all the types and I found the foam tips, and small flange tips to be the most comfortable.

As for the looks, well, they look rather plain (which suits me, I like plain designs) but just a heads up, these are not a fashion accessory. However they were never intended to be one!

At first listen to my ears the sound seemed a little bit dead, but given some time to "burn-in" the sound improved dramatically.

The sound itself is pure brilliance, the sound quality is very natural, and clear. With excellent tonal balance between treble, mid and bass. The bass response is good without being overpowering, if this is what you are looking for you will be satisfied. However if you are a bass-head and want pounding bass, you should look elsewhere as you are not the kind of listener that needs accurate headphones like these. The dynamic response is excellent too.

As a musician,audiophile and absolute lover of music I feel it very important for anyone considering purchasing these headphones to have the prior guarantee that these are quite simply breathtaking!!!! I have in the past purchased so many iems from sennheiser, shure,ultimate ears triple 10s,klipsch all top end models costing a fortune,and sometimes got close to what I felt was that sonic nirvana, but these are by far in my opinion the best set I now own.Even out of the box first time you get that wow factor , these are a serious set of phones they sound absolutely superb. the first thing to say is that the sound of these is only as good as the source material im afraid, garbage in garbage out!!! but all this means is that if you are using an ipod make sure youve downloaded at high bit rates or apple lossless. I only use mine with an ipod and the sound that can be obtained is simply stunning, but I also suggest that you . use a headphone amplifier either the e11 or the new e12 (check out mine and others reviews) soundstage is spacious and the separation of each piece of instrumentation is amazing(these headphones are remarkably accurate in this respect).I can honestly say that this is the first time that ive really felt wow!! the realism that these create is superb.Bass is woderfully presented in a perfectly accurate way its punchy and crisp and if the recording produced thunderous bass then thats what youll get. Midrange is amazing ( particularly listen to a recording which includes cello and they will demonstrate this beautifully, and the clarity that the top end produces is so detailed, no wonder sound engineers use these I can hear why.these have made my whole listening experience so much more enjoyable.Read more ›

I own a couple of other IEMs, a pair of ACS T15's and an old set of Super Fi Pro 5's. I've been using the T15's with some custom sleeves exclusively for a couple of years but about a week ago decided to try the Super Fi's again. I was really surprised as the Super Fi's made the T15s sound shut in. However although the Super Fi's sound open they also exaggerate both the bass and treble which means the sound can get quite fatiguing especially the treble which can become a bit harsh.

At this point I started looking for a replacement for both sets of IEMs and thought I'd try the Etymotics as they have been very well reviewed for years now. I was a bit concerned that they may sound shut in like the T15's - I needn't have worried! I originally tried the silicon tips that come with the earphones but found that the silicon tips didn't seal very well which meant I heard no bass whatsoever and the entire sound was very thin. I then tried the foam tips, this improved the sound a lot however the seal still wasn't entirely there.

I've now found that with a good push I can get the Etys into the custom sleeves I had made for the ACS T15's - sonic nirvana! I now have a great seal, great isolation and can appreciate the sound fully but it doesn't end there! This ER-4PT set also came with the 75 ohm adapter that converts the ER-4P into the ER-4S, I use this as I've found that it makes the sound even more balanced and also makes the treble sound even sweeter - I love them - highly recommended.

which I would describe as being balanced with a lovely sweet treble.
