Basics The DUNU ( @DUNU-Topsound ) DK-3001 PRO is the successor to the DK-3001 and the latest model in DUNU's DK series of hybrid in-ears. It is a 5-driver hybrid, with a dual BA tweeter handling the highs and super-highs, two single BAs handling the mids and upper mids, and a 13 mm dynamic...

Just leaving this here...       Product Page Feature Sheet (PDF)   Frankly, I was disappointed by the NAD Viso HP20, but I loved the HP50 (as did many, many a member).   To my eyes, a hybrid design doesn't feel like the MO of Paul Barton, but I guess I'm wrong. I hope that it's good.

**Note: NOT an April Fool's Announcement**   I'm a big fan of Custom Art. I have both the Music One and the Music Two silicone CIEMs. To me, they represent some of the most well-rounded silicone CIEM products on the market. The company itself, begun by fellow head-fier @piotrus-g in Warsaw...

Celsus Sound Companion One   This is an exciting product --- I've been testing out this portable DAC all-in-one for the past few weeks, and it's pretty darn cool, with all the bells and whistles a portable DAC can possibly have. The digital heart is an ES9018K2M found in many portable devices...

In recent months, as part of FiiO's internal testing programme, I've been privileged to test out revisions to FiiO's well-received E10 and E11 products, the E10K and E11K, respectively.   The E10K and E11K, despite being named 'K' revisions of the original models and thus might connote minor...

  http://www.didit-highend.com/index.php/products   Anyone heard of this thing? Looks like a newly formed company, but claims three years of R&D for the DAC212. I can't find any real information on the company, or when/if the DAC212 will release.   The phone number has a +31 country code...

UPDATE, 2014-10-30   Looks like they've come live with a nicely polished website: http://www.marvalveaudio.com/index.php   Some design features it claims:   Innovative circuit design No-feedback circuit design for pure sound and better transient response.   Sounds pretty good to...

Post pictures and/or videos/stills of recording artists, celebrities, sports figures, etc. wearing custom in-ear monitors (or non-IEMs as well) on stage or elsewhere.   Commentary is welcome, including, but not limited to, what brand of customs they're wearing, what have they worn in the past...

For the past few weeks, I've been examining the a very unique (and innovative) cable from Danish manufacturer Estron, the Linum BaX cable.   Estron's Linum BaX MMCX cable fitted to a Westone UM Pro 20   At only ~0.9 mm in diameter, the Linum really is as thin as it looks; when I first...

The famed Swedish brand from Jenving is taking the plunge into headphones.   Any bold Scandinavians want to take the plunge?   http://www.supraheadphones.se/inear.html http://www.facebook.com/supraheadphones   I have no idea what the compensation is, or whether it's measured with a...

Only the Japanese press has picked up on this development. The rumor is that this is a four-driver (1 high, 1 mid, 2 low) IEM priced to be under $500. Certainly, we've never seen Nuforce venture this far upmarket with regard to their earphones, so this is an interesting development.  

At this point, it shouldn't come at a surprise that yet another CIEM lab (so many choices, so little money; I know, right?) has sprouted up in the midst of massive growth for the custom IEM market. The existing guard of CIEM companies has long been intricately tied to the hearing aid/protection...

Firestone Audio is really stepping up its game these days, with increasingly higher-end products, like the Tobby/Bobby.   As a followup to their previous HD offerings, they're coming out portable balanced amplifiers: the HDB amp and DAB combination DAC/amp.   These pictures were posted on...

A few weeks ago, I was approached to take a listen to the MOE Audio SS01. This is a quick review of these earphones while everything's fresh in my head. Beware that I rarely hedge on fast thoughts short on post-processing. The writing is loose, and my diction is as pungent as a clove of garlic...

Anyone hear them yet? Like the HP50, they're supposed to be developed by Paul Barton, so from all indications, they should be quite good and neutral (according to the NSC's Project Minerva, it's +3 dB/octave from 200 Hz down to 50 Hz for bass boost, reasonable enough, I guess). They don't look...

Today, I managed the privilege of listening to some demos of CIEMs from a company on the eastern coast of Italy, largely unknown to the head-fi community, called Livezoner41.   I first heard about this company from the Japanese, who are incredibly adept at finding new and unique CIEM...

INTRODUCTION   TBH, I haven't been the biggest fan of Astrotec --- they always seemed to have great potential, but again always seemed to deliver just short of that promise.   I've also not been a great fan of hybrid dynamic/BA IEMs. However, ever since the AKG K3003 released in 2011, it has...

This post is a review of the CustomArt Music One single-driver, silicone-molded CIEM. Piotr Granicki (aka piotrus-g), proprietor of CustomArt, originally sent me the Pro 100 for review (see the second post of the thread). Recently, because of canal fit issues, I had the Pro100 model remolded...

CustomArt Copper Two   I don’t know much about Poland; the only things I knew were antiquated truisms --- that it was the gateway to the eastern bloc and that it had a relative abundance of kielbasa. Other than that, I was pretty much clueless. However, ever since joining head-fi, I found out...

Portable Amplifiers from the Far East...     I would like, firstly, to declare that my experience with portable amplifiers has been limited. I’ve heard my fair share of them, but have never made them a priority, primarily because I didn’t like carrying them around, regardless of how...
