harschacoustic SH-2 - Looks

First of all, I would like to thank Samuel from P.EAR.S for sending me the SH-2 for review.
P.EAR.S was created and founded by Samuel Harsch, also known as the co-inventor of vital audio characteristics of the  Audéo PFE series. To this day, the best universal earphones I’ve owned and reviewed is the Phonak Audéo PFE 232, a set of MSRP £400 universal earphones, which only housed two Balanced Armature drivers, but had such an amazing crossover that the two drivers in the PFE 232’s compete with 4-6 driver BA drivers found in other earphones.

Therefore, when I saw Samuel created his own earphone, I was excited to see if I could review it – as I wondered if he improved/added to the PFE 232s sound and created it into a CIEM of his own.

Before getting into the review, I would like to state that this is my first CIEM review, I have previously reviewed/heard a lot of earphones (in excess of 100 different earphones), but never ventured into the CIEM world, as I’ve previously had problems with fit. For example with the 1964-SLV Universal IEM Custom Sleeves, the Custom Art custom tips and even tried going to a professional audiologist in London as an attempt to get a good fit for custom sleeves for the PFE 232s. No matter who I tried or how many times I tried redoing the impressions they didn’t work – and I always had the impressions done by a professional audiologist.
I was therefore going to give up trying until I saw the SH-2s, where I thought to myself – I have to give this one more go and if it fails, then I’ll give up for good on CIEMs.
I was lucky enough to get good impressions at my local Specsavers for only £29 – which I was sceptical about. I will expand on this in the comfort section.

More information on the SH-2s, including specs can be found on P.EAR.S’s website!

DUNU DN-2000 - Nozzle


First of all I would like to thank DUNU for sending me the DN-2000 for review. After having reviewed the DUNU Titan 1 and being mind-blown by the value for money they offered I was very much interested to see how the DN-2000 compared. I saw them being compared tot he likes of the AKG K3003’s and I was even more interested to see how they would compare with my personal favourite universal earphones, the Phonak Audeo PFE232.
The DN-2000 can be bought on AmazonUK for £250 and on AmazonUSA for $265. Yet again the UK/EU get horrible price conversions – the difference between UK and USA is near £100 – which is massively different.
As I live in the UK, these will be reviewed at £250.

The specifications of the earphones can be found on DUNU’s website.

To complement the written review, here’s a video review of the earphones:

Custom Art – Silverline Interconnect & PFE232 custom tips – An amazing experience!

I recently bought Custom Art’s Silverline Interconnect for my portable rig and a set of custom moulded ear tips for my PFE232’s.
First, the cable:
I wanted a durable, flexible, good quality and good looking cable. Custom Art offered a cable like this for a very reasonable price of £21.
I went ahead and bought the 7cm interconnect, that has a straight jack on one end and an angled one on the other – it also is triple braided with a 5N silver cable.

I got the cable in, and ever since I have had it in my possession, I’ve loved every minute with it. It brings out the mids of the PFE232’s and doesn’t dampen the quality of the music, unlike with other cables I’ve tried in the past. More so, the cable is so tiny and extremely flexible that it works very well with my rig.

The cable was thus perfect and I hope it lasts very long for me.

Here are some pictures of the cable:

Unto the ear moulds:
The custom ear tips were extremely small in size, meaning they aren’t like full custom ear moulds. That said, with it being custom, it would block out more noise than your average ear tip. I thus went ahead and bought that for around £35. The price was extremely reasonable and very much affordable.
The quality of the finish of the ear tips is top-class, and really well done. The only negative thing I found on them, is that the hole on the end of the ear tip, meaning that the soundstage of the earphones was slightly reduced. That said, after speaking with the owner of Custom Art, Piotr, he said he could easily open the hole, in order to widen the soundstage a bit. He chose to put a small hole as it was how the PFE232’s drivers were, which is completely understandable, in order not to modify the sensational sound of the PFE232’s.

The ear tips, increased the sub-bass response and power of the mid-bass of the PFE232’s, but also due to an earphone tip that doesn’t alter the sound, unlike the Comply Foam tips, the mids were also a bit more up-front. As said above, the soundstage felt a little less open, but that could have easily been changed.
Overall the sound quality was an improvement, and the experience was great. However, for me the earphone tips weren’t comfortable for long periods of time. This has nothing to do with Custom Art, as I had the same discomfort with my 1964ears ear moulds. Thus meaning the earphone tip impressions were at fault, not the ear moulds themselves.
If I get around in making new ear impressions, I will send my tips back to Piotr, in order for them to be re-moulded (he was very kind in letting me do that).

Here are the pictures of the ear tips:

I hope this posts helps you out!
I would strongly suggest buying from Piotr, as not only was his products and craftsmanship excellent, but his customer service was absolutely phenomenal. A MUCH BETTER experience than dealing with other custom earphone companies out there, be it in the UK or in the USA.

1964-SLV Universal IEM Custom Sleeves for Phonak Audéo PFE 232


In summer 2012, I was visiting my family in California, USA for a month of sunny holidays.
Whilst I was out there, I thought to myself to get some custom sleeves done. I had previously, from the UK emailed 1964 Ears to see if they would do the PFE 232’s – The reason being, is because the PFE’s have a slightly larger nozzle than your standard earphones like the Shure Se535’s ones. Thus I couldn’t find a reputable custom earphone company within Europe that would do them. All of them that I called, emailed, either hadn’t heard of the PFE 232’s nor would do them. For example, I got in contact with ACS in the UK, and they said they were unavailable to do it; I’m sure there are other companies out there, that could have done it, but I wasn’t aware of them at the time.

Review of the Phonak Audéo PFE 232 – The Best Universal Earphones I’ve Heard to Date

Pros: Highs, Mids, Bass response for BA drivers, comfort, build quality
Cons: Sibilance, price, isolation, needs to be driven

Packaging & Accessories: 9/10
Build Quality: 10/10
Design & Look: 10/10
Microphonics (higher ratings means lower cable noise): 10/10
Isolation: 8/10
Comfort: 10/10
Audio Quality: 10/10
Value: 7/10
My final Rating: 9.5/10

Purchase Date: April 2012
Purchase Price: £400

First and foremost, I would like to send out a huge thanks (and hug?) to David, over at Phonak Audéo in sending out the PFE232’s to me, for review!

I would also like to point something out about the PFE232’s in relation to the P-Series tips – this was made aware to me by Comply:
“This tip series has a threaded core. While this core is fairly flexible and may stretch to accommodate the sound port of the PFE232 – there is a significant risk that attaching or disengaging a P-Series tip would damage the sound port. I highly discourage any customer from using the P-Series tip with this earphone. Any time you force a tip that is too small onto a sound port, you risk stressing that sound port in such a manner that could cause damage. We have heard of, and have experienced, cracking or breaking of sound ports in these situations (not speaking of Audeo specifically, but of forcing or attempting by force to put a tip onto, or remove a tip from a device that is not compatible with the Comply™Foam tip used in the attempt.)”
(Thus, please do not use the P-Series tips with your PFE232’s)

The Phonak Audéo PFE 232, also known as the PFE232’s are one of the best earphones I have heard to date. These earphones define for me the best universal fit earphones I have ever heard. That said, these do have some slight flaws, such as their sibilance, their isolation and most of all their price tag.
Apart from those few things, the PFE232’s I find are a class-leading earphone, whilst maintaining only 2 Balance Armature (BA) drivers in each ear piece.
Without further ado let’s get on with this review!
