Introduction By now, I'm sure many portable audio enthusiasts are familiar with the AliExpress shop NiceHCK. No doubt, it has been offering its services for the platform for many years and is highly valued by buyers. It is a well-earned reputation. It is also true that for years it has been selling its own branded products, such as earbuds, IEMS and cables. He has even ventured into top-of-the-range earbuds and IEMS, such as the model we will review in this article. This is the NiceHCK Himalaya, a titanium alloy IEMS with a dual magnetic dynamic...

This time, they have collaborated with Crinacle, one of the world's most reputable audio critics, to create the new Kiwi Ears Singolo.

Introduction Once again, another product from the brand launched in 2017, Tiantian Dongting TinHiFi. With their motto based on trying to listen to the world, it is possible that, on this occasion, they have listened to me... After two models that were far from my preferences, such as the last iteration of the T2, the MKII and the C0, their new T5S model has hit the nail on the head. It is true that it is clearly more expensive, costing around $130, but its price is the same as its previous T5 version. With improved aesthetics over its predecessor...

Introduction In many ways, talking about Letshuoer is like talking about planar IEMS. And although it is true that Shuoer existed before its famous S12, this planar continues to be a reference within the $100 IEMS, at least in my country. But, I think it would be unfair to only talk about the S12, when the brand founded in 2016 has other great models to its credit, some of which I have had the pleasure of testing, such as the latest S15 planars, the S12 Pro, the DZ4 and the D13. It is clear that the brand does not live by planar drivers alone and...

Introduction Once again, and in a very short space of time, I am once again reviewing a product from Rose Technics. Since 2012, the Chinese brand has produced a multitude of very interesting models, especially in the field of IEMS and earbuds. Previously, we have seen that they have also made the leap to TWS, but I still think that their great value is still in wired headphones, something you could already see in my review of the excellent QuietSea. Rose Technics continues to delve into somewhat distinctive and differentiating profiles. Proof of...

Introduction I must admit that headphone brands from China are like flowers in spring: there are many, many different ones, and a new one is appearing all the time. ZiiGaat seems to be one of them. However, they have been developing OEM and ODM products for numerous global audio brands for more than a decade. Their passion for audio has led them to found their own brand. The name ZiiGaat is an acronym derived from their core values: Zero-in on Ideas, Innovate, Grow and Achieve All Together. They express their desire to collaborate with the...

Introduction Simgot, the brand that stands for "Simple and Elegant" has re-released a flagship model that uses a second-generation dual-cavity magnetic dynamic driver. This is the Simgot EA1000 Fermat. Upgraded directly from the EA2000, the EA1000 utilises cutting-edge technologies such as SDPGD™ technology, the powerful DMDC™ dynamic driver and the 1DD+1PR hybrid architecture that delivers a fuller and more accurate high-quality sound, greatly enhancing the listening experience. The EA1000 incorporates Sputter Deposition Purple-Gold Diaphragm...

Introduction Rose Technics, the portable audio brand established in 2012, is betting on TWS technology. It currently has 4 such products on the market: Earfree-i3, Lightyear Star Ring ANC, Beetle and the Ceramics model, which is the subject of this review. With the most expensive product costing $44 and the Ceramics currently priced at $30, these products are in the budget segment. The Rose Ceramics have a 10mm dynamic driver with DLC diaphragm, they specify that a 10-minute charge can provide 6 hours of playback, while a full charge (40 minutes)...

Introduction This is the first time I have reviewed an ifi product. Although I own the ifi ZEN CAN which I bought some time ago, I had not tried a source from this brand. Established in 2012 and with a distribution centre in the USA, ifi has its own way out of the other brands from the east. Very faithful to the Burr-Brown chips, the brand has a classic touch in its sound that is already a trademark of the house. This time I have been able to enjoy on loan for a few weeks this small portable DAC/AMP in its third generation, called if hip dac 3. It...

Introduction The popular AliExpress shop specialising in portable audio products has re-released a new low-budget IEMS model. It is a hybrid model with a dynamic driver and a BA driver. The dynamic driver has a 10mm titanium-plated graphene diaphragm. The BA driver is integrated into the mouthpiece channel, to reduce any loss of high frequencies. A PCB board with an electronic frequency divider is included. A similar process to the top model NX7 MK4 has been used for its manufacture. The front panel is made of drop-moulded resin, with an aluminium...

Introduction EPZ is a new brand to me, established in 2019. It's not a new brand to the public though, as it has a good catalogue of IEMS, cables, TWS, even dongles to its credit. And that's not a one day thing. Although it is true that it is now becoming better known to the general public. Manufactured by Shenzhen Jiuzhou Electronics, EPZ has its own shop on AliExpress and it is there where you can corroborate what I have said and see the number of models they already have. It is true that there is not much more information about it and that is why...

Introduction Hidizs has brought a new small dongle to the market. It is true that they have several, and some small ones like the S3. But it seems that they are still looking for a more appropriate design for use in conjunction with the smartphone. I'm the first to think that having an extra cable hanging from my phone can be a nuisance. But how about creating a much more integrable design? I think that could have been a starting point for Hidizs' new product. The SD2 is a small, irregular pentagon-shaped dongle with a USB Type-C male connection and...

Introduction There's always a first time and today it's a double first time. From AliExpress shop Angeldac Audio Store, today I have the pleasure to review a Muse HiFi dongle. Shenzhen Yunke Acoustic Technology Co., Ltd. is an innovative technology company that integrates research and development, production and sales of HiFi audio equipment. The company's purpose is to pursue the ultimate in the ultimate and to discover simplicity in the simple. To their credit they have different IEMS and other dongles. In this case I am going to review the second...

Introduction Tempotec started in the DAP world with the V1-A, a small player that had a transport-only version with dual micro-SD slots and a DAP version. It was just a small sample of what Tempotec could do in this field. But it was a long time before it released the V6, its first Android-based DAP. A little over a year later Tempotec is back on the attack with a new model: the V3. It is a sub-$200 DAP capable of rivalling all the DAPS on the market in this range. This time, Tempotec uses HiBy OS as operating system, although its sound hardware is...

Introduction Founded in 2015, Rose Technics is an emerging audio brand that has spent years in the pursuit of unparalleled original sound reproduction through intelligent technology and meticulous craftsmanship. I can't hide my fondness for this brand and have been lucky enough to review some of their great models, such as the Mini2 MKII 2.0, the QT9 MK2 and QT9 MK2s, as well as the Martini earbuds. And I have to admit that each of them is on my list of favourites in their respective categories. So it's no wonder that every Rose Technics model that...

Introduction Tiantian Dongting TinHiFi was launched in 2017. TinHiFi gets its name from the homophone of "Listen" and "Hi-Fi". On the other hand, the brand advertises that one of its best assets is that it tries to listen to the world and, with that, to the users who buy its products. They claim that, although the T2 model has already been iterated several times, it still has room for improvement. This time, thanks to users, they have opted for clearer and more transparent high frequencies, as well as cleaner, more controlled, more precise and...

Introduction Simgot, the Shenzhen-based company founded in 2015, once again lives up to the meaning of its name, "Simple and Elegant", with the EM6L model. This is a 5-driver-per-capsule hybrid IEMS (1DD+4BA) tuned to the H-2019 target curve. This reference has been universally acclaimed for its three-frequency balance, accurate soundstage reproduction and precise imaging. The EM6L combines a dual-cavity dynamic driver with a custom-designed 8mm polymer diaphragm. In addition, two sets of balanced armature transducers handle the high-midrange and...

Introduction As usual with the great Hidizs models, they have released a limited edition of their latest IEMS model with planar technology. This is the Hidizs MP145 Limited Golden Titanium Edition. It is available in a limited run of only 199 units. The packaging includes two types of cables, one with a 3.5mm plug and one with a 4.4mm plug, as well as a 10th anniversary badge. Each product has been uniquely numbered in the world. Again, Hidizs uses titanium known for its superior properties that make it ideal for making Hi-end capsules. Of course...

Introduction The already famous 7Hz brand is once again launching a new collaboration with the famous In-Ear Fidelity founder and YouTuber, Crinacle. Of course, it's the new 7Hz x Crinacle Zero: 2. This new model features a 10mm dual-cavity dynamic driver with a PU+Metal composite diaphragm. The result has been an improvement in bass and midrange, as well as faster diaphragm movement, giving a clearer, more accurate and punchier sound. The standard cable has also been improved by using a high-purity, silver-plated, oxygen-free copper conductor...

Introduction The famous AliExpress portable audio store NiceHCK released its evolution of its first F1 planar IEM at the end of 2023. Sure enough, it's called F1 Pro. It is a new model containing the next generation of the 14.2mm planar diaphragm driver. It is 2µm thick, uses N55 neodymium magnets and a double-sided magnetic circuit. The capsule is made of aluminium alloy and the ergonomics have been improved compared to the previous model. This time there are no different mouthpieces to change the tuning, but the profile is unique, slightly more...
