AYA Audio Nightingale YK-1: Twinkle little star What are the countries that first came to mind when thinking about IEM manufacturing? Most likely it would be China, USA, or Japan. Though China brands are particularly taking the lead in affordable or cost-effective IEMs, prompting many other manufacturers to work on affordable products. This ongoing trend led manufacturers from other countries to build solid reputations, one of them being AYA Audio from Vietnam. AYA Audio is an affiliated company derived from Soranik, another Vietnam brand that...

Hifiman RE2000 / RE2000 Silver: Straight forward Hifiman is one of the largest manufacturers in portable audio, especially for producing high-quality planar headphones. While they were continuously presenting a series of new headphones, they've been rather quiet in their in-ear products until last year, presenting RE2000 and RE800 in both gold and silver variations. I visited Japan's Fujiya-Avic headphone show and got to try both models which left we a very positive experience. It was also great to see Fang Bian, the founder of Hifiman. Having some...

IMR Acoustics R1 Zenith: A proper upgrade IMR Acoustics is a UK based manufacturer and founded by Bob, both the owner and the engineer. Their first model was the R1 which was quite successful for its cost-effective performance, as well as featuring a world-first 'open and close' vent system with changeable filters. Now IMR announced their second product, the R1 Zenith. It's meant to be the most ideal version of the R1, achieving the peak performance as well as supplementing the flaws from the original one. Here I'll mainly be focusing on compare and...

Rhapsodio Eden: Reference heaven Rhapsodio (short in RSD) is an earphone/cable manufacturer based in Hong Kong which is known to have a sturdy fan base throughout the audio communities. Previously I've reviewed the Zombie MK8, the flagship model from their hybrid line-up, which I still use as one of my daily drivers. Eden, on the other hand, is RSD's flagship model from their dynamic driver line-up and a successor of the Galaxy models. Eden has been released earlier this year, making its way to gain the spotlight of 2019. Let's go through the...

Satin Audio - Monster Series: A solid new brand Cables are one of the most important elements in personal audio when it comes to sound quality and getting closer to your desired sound. The quality of the cables are pretty much guaranteed for the big, famous brands, but what about the cheaper options? Sure, there are still a whole lot of choices you could make for an affordable price, but in my experience many of those just weren't good enough or turned out even bad at some times. However I've recently discovered several cable manufactures that are...

ADVANCED M5-1D: Big leap Advanced (ADV) is back at it again with the premium line up, the M5 series. Currently two models have been officially released, which are M5-1D and M5-5D. Memories are a bit vague, but I recall them also working on 8D and 11D when I visited their booth last year. 1D has a driver configuration of 1DD while 5D is 4BA+1DD and each of them priced for $399 / $599. As someone who's been into ADV IEMs, I had to check out how they would do with their premium products. I've purchased the 1D soon after the release and now I've spent...

Periodic Audio Review: Only the necessities Periodic Audio (PA) is a startup brand that has just hopped onto the audio industry. Periodic Audio is from California, USA and introduced themselves with some unique concepts or principles which intrigued me to learn more about. As they announce their first three lineup of their product, Mg, Ti, Be, they've set their principles very clear: single dynamic drivers are better than multi BAs. While some companies target their products on people's emotion, PA takes a very scientific approach towards their...

Dunu Falcon C - Flies high, strikes hard Dunu is one of the most popular, fastest-growing Chinese brand that's been showing a steady success with their products. My experience with Dunu was mainly related to their hybrid models - DN2002 and DK3001. DN2002 had an outstanding performance while DK3001 was even better, for both sound and fit. Then last year I stumbled across a teaser from Dunu, revealing the Falcon-C. As a DD fanboy, I just had to give it a shot. Falcon-C is so far their flagship DD IEM beyond the Titan series and retailed for $219.99...

Zombie takes up the flagship title among the hybrid line up and also has been receiving positive feedback, which I...

Astrotec Delphinus 5: Flagship nicely done Astrotec is one of the earliest generation to be manufacturing cost-effective IEMs. Astrotec themselves consider them to be a rather unknown brand, though I'm quite sure that you may have heard about the brand if you were one of those that were looking for an entry level earphones from China. Well, at least I remember purchasing or getting curious about their old models back then, such as AX-30, AX-35, and Lyra 6. Astrotec wasn't the fastest when it comes to releasing new products, but they've been...

DITA Twins Review: Fidelity or Fealty, that is the question Dita is a worldwide brand that manufacturers premium earphones. Not any earphones, but with only single dynamic drivers. Their entry model, the Answer, is probably one of the most popular IEM and their higher models, the Truth for example, also gained good amount of popularity. Of course, it's important not to forget about their limited flagship model, the Dream, which gained incredible feedback and interest among audio communities. Though most of all know that the Dream was only produced...

I've been testing out their gears since they started their company and was satisfied with their products being solid and cost effective.

It was a great...

Intro: Advanced to another level Campfire Audio is a leading audio brand that started small but quickly grew its reputation making hits after hits. Back then, I remember Orion and Jupiter gaining lots of attention since they came out and I eventually got the Orion. Although I have a pretty omnivorous taste when it comes to sound signatures, I rarely falls in love with 1BA in-ears. Orion was one of the few 1BA in-ears that I've been enjoying and it's still in my possession, serving me well as one of the old gears that I have. CA is one of my...

Intro Chi-Fi has been flowing through the audio market recently. Whizzer is one of the new Chinese brands that came up recently and they've announced their first product, the Whizzer A15. During then I started to have interest on them, though one fact came to me as a concern; barely any information was available about the brand back then. I’ve thought they could possibly be those typical DIY earphones available on the Chinese markets, but soon I've realized that wasn’t the case here. Anyway, the A15 Pro is the second product they've recently...

AZLA Horizon: Sunrise and a new brand breaking through AZLA is a fresh new firm from Korea which made their debut with the AZLA-01R (or simply called as AZLA) in Japan. Because they didn't acknowledged to the users about their nationality, so I supposed them as a Japanese brand back then. AZLA was definitely an eye-catching brand and gained enormous attention when they made their first appearance with the 01R in Japan exhibitions. Getting a satisfying impression, I soon bought AZLA 01R before coming back home and they still pleasure my ears. Then...

Intro IMR Acoustics is a new in-ear brand around the block, founded by Bob who previously worked with Trinity Audio. So who is Bob? Before talking that, let me first give a brief insight about Trinity Audio. TA has been considered as one of the popular manufacturers for their active communication with the users and for their cost effective gears. Bob was the one who communicated with users and managed the entire making of their product. Now, as a guy who used to be a TA fanboy, I’ve tried almost all of their gears since their debut to Kickstarter...
