2024.05.16 23:51 mr_boizoff Truthear x Crinacle ZERO: RED Earphones Review
A job change and all sorts of other adventures made me take some time off from the reviews. But, as the saying is, "Don't count on it!" — there will be a lot of them in the short run, and they will be interesting, well balanced and spot on! submitted by mr_boizoff to headphones [link] [comments] In short, let's talk today about the in-ear wired earphones Truthear x Crinacle ZERO: RED (or just RED later on), which I purchased for about $55 you know where. https://preview.redd.it/9ywolwakyu0d1.jpg?width=1800&format=pjpg&auto=webp&s=57da9791a73200cc6d3c99ce8a3c061657ae7bb8 By the way, my old camera broke down, so I bought a new one, that's why the pictures will be even more unbelievably brilliant now. Come on and get a look, all the pictures are clickable, as always. Truthear in a nutshellTruthear, a Chinese company, has just turned 2 years old, but they have already released 5 models of earphones and one portable DAC. The company was allegedly founded by one or more Moondrop people. With all the trimmings of modern Chinese fashion, Truthear has a mascot, which is an anime girl named Shiroi, weighing 45 kg, 170 cm tall and... I have no idea why I say all this.Their partner in the field of 3D printing technology is HeyGears, whose equipment or capacities, I believe, Truthear uses to produce its devices (at least, earphones). What's includedThe proud owner of this top-quality cardboard box will find in it as follows:https://preview.redd.it/ea3yvoxpyu0d1.jpg?width=1800&format=pjpg&auto=webp&s=bd5ea91ac6fdb1ec11c76dd3f8c77c81b7b7b7e9 1. the earphones themselves; 2. a cable with a 3.5 TRS connector; 3. an adapter with an additional load of 10 Ohms (I'll tell you why we need it later); 4. a set of 7 pairs of eartips; 5. a fair-to-middling cover made of faux leather; 6. a pile of papers with the image of Shiroi. The box, I will repeat myself, is perfectly made, I've never seen anything like this. I'm totally cool with the set, it's a good one. Technological features, build qualityRED use a less common structure 'a larger dynamic driver + a second smaller dynamic driver'. The first one is responsible for the subbass and bass up to 200 Hz and has a diameter of 10 mm, and the second one plays the rest of the range and has a diameter of 7.5 mm.The manufacturer talks about the 'CCAW voice coil', that is, about the fact that the driver coil is made of copper-plated aluminum wire. Usually, when it applies to headphones, this is made to reduce the weight of the driver's mobile system. This technology is not new: for example, it is also used in Moondrop Aria Snow. Besides, 'DLP', or 'Digital light processing', 3D printing technology is mentioned. This is a three-dimensional printing process, characterized by high accuracy and the ability to correctly reproduce extremely small details. And the last but not the least, the earphones are optimized for use at high volume (over 94 dB) and configured in accordance with the 'IEF Neutral 2023' curve by Corin Ako (better known as Crinacle), but with some adjustments in the bass and subbass sections, giving the sound of RED more weight and physicality. So, RED are earphones printed on an industrial 3D printer, based on a 2-driver scheme. And Crinacle, a well-known reviewer and owner of the largest IEM measurement database, is responsible for tuning RED. The earphones have a simple but distinctive design. The enclosures are completely glossy and slightly transparent on the inside. On the outside, there are mildly glaring red inserts under a coat of varnish. https://preview.redd.it/5og1uxwsyu0d1.jpg?width=1800&format=pjpg&auto=webp&s=b0403d22e9fcb489cf8da789149869145fcf8349 You can discern bass speakers inside at a definite angle. https://preview.redd.it/9v2r688uyu0d1.jpg?width=1800&format=pjpg&auto=webp&s=846183aa032e50b66ae4344c5af8fe6109e1cc26 The grids of the sound ducts are neat, inserted smoothly. https://preview.redd.it/6b569ycvyu0d1.jpg?width=1800&format=pjpg&auto=webp&s=4a2a9a4c28e277808efd6e80c2b767457ee7e640 There is one compensation hole per each earphone, located in close proximity to a 2-pin connector. L and R are marked in bright golden letters. Small edgings for fixing the eartips were made, too. Overall, they are quite good and even stylish. The only issue is microscratching that affects the enclosure right off the bat. But it's not really perceptible to the eye. On top of that, the earphones act as a magnet to fingerprints. The cable is just decent. It doesn't get too tangled, and the earholders are made at the right angle. The metal splitter is solid black, with the company logo printed on it. https://preview.redd.it/c7331knwyu0d1.jpg?width=1800&format=pjpg&auto=webp&s=d66836329928887b3fc396b7bb6596bf486eae20 The very same cable comes with Truthear HEXA and Zero earphones. The case is made decently, too, but it does not have any internal compartments or partitions. I already wrote about how an adequate case should be designed 5 years ago – no one has released anything alike yet. https://preview.redd.it/3rbvma2zyu0d1.jpg?width=1800&format=pjpg&auto=webp&s=cc21b72be8af06e6cd816a5903135b0e1255c46a ErgonomicsThe geometry of the RED enclosures turned out to be perfectly compatible with my ears. They don’t have any strange concavities, bulges, or sharp edges, the sound ducts are positioned at a natural angle, the dimensions of the enclosures are... ordinary, only a little thick. Just put them in and listen to music. And they don't have much weight at all.I'll assume that the sound ducts may turn out to be uncomfortably large for owners of small ears, because, let's be honest, these are not sound ducts, they are simply muzzles. Probably, when you get a first taste of these earphones, you will want to change your favorite eartips for the same, but smaller ones. The flipside is the noise insulation — RED's one is above average because the earphones fit in tightly. As for the 10-Ohm adapter, it is not convenient to use it on the go: a few centimeters long, thin rigid structure will stick out of the player audio output, which can easily damage the connector if stressed accidentally. Quick specifications overview
Subjective sound impressionRED sound great: balanced and new at the same time. Imagine that a 'top-up' of a very weighty and fast subbass was added to neutral sound delivery, which never overlaps the bass for a moment, not a iota, let alone the mid-frequency range. What's more, a lot of well-articulated high frequencies were poured in (we're talking about the 3-10 kHz range), but not those that get sandy, filled with sibilants that grate on the ear. They are just heard very well. This is, you know, sort of 'a joy of a HF-phobe who still wants a lot of HF'. With this in mind, the middle range is perceived to the utmost, there are no dips and curbs there, and it is just excellent.The result is a 'smooth', but vibrant and simultaneously informative sound delivery with a stable low-frequency basis, perceived as 'dynamic' and 'detailed'. It is ten kinds of cool, simply brilliant tuning that retains its uniqueness and accuracy far beyond the price category of these earphones. Against the background of the high frequencies delivered in this fashion, RED have a clear and wide virtual sound stage with a clear localization of instruments. It could be better, but in a very, very different price bracket. Why the RED sound might not work for someone:
MeasurementsThe earphones were connected to the RME ADI-2 DAC (IEM output). A measuring rig conforms to the IEC60318-4 standard. The provided eartips were used for measurements. The smoothing is indicated on the graphs. For the info about rigs, graphs and headphones measurements, refer to my article.Frequency response: https://preview.redd.it/eri2gsdezu0d1.jpg?width=1600&format=pjpg&auto=webp&s=290174f139b73f2f312471e985e624548293bc9b Keep your eye out for the dashed green line – this is the target curve conventionally named Crinacle Neutral Target 2023. This target curve was proposed by Ako in April 2023 as an alternative to the Harman curve, which is appreciated by far from everyone. The diffuse field curve measured at the Type 5128 rig manufactured by Brüel & Kjær was used as a basis, which was then transferred to the IEC711 rig and 'tilted' clockwise. Why it was done and why this way – I will try to answer these questions in detail in another article on the theoretical part of measurements, but I won't go deep at the moment. What matters is that this is not just a tuning. This is a very specific tuning that has been contemplated on for quite a while. To put this in perspective and see something more common, here is the frequency response of RED and the most current Harman curve: https://preview.redd.it/hi0j1bkuzu0d1.jpg?width=1600&format=pjpg&auto=webp&s=8fd9854f18d81798fc43e769f6eca16027dbb144 And the situation here is very interesting:
As a reminder, there is a 10-Ohm attenuator included. https://preview.redd.it/gna9eigwzu0d1.jpg?width=1800&format=pjpg&auto=webp&s=cb2c1b9ed0b29c76a2e156215626383ff72c6ca4 When it is connected, the left part of the frequency response graph rises predictably, and the sound becomes more 'common': https://preview.redd.it/n5egvhryzu0d1.jpg?width=1600&format=pjpg&auto=webp&s=5b3d26d901780a7eca911071bd68f838b2ce6b88 The left/right volume balance is not ideal, but acceptable: https://preview.redd.it/iwsc9mh00v0d1.jpg?width=1600&format=pjpg&auto=webp&s=e7fb32e88c180e2183a53c7747464d5ab8382ef5 Nonlinear distortions (these are measurements that should not be 100% trusted because my equipment is far from perfect): https://preview.redd.it/m8ozge320v0d1.jpg?width=1600&format=pjpg&auto=webp&s=0b47fde9e64b1857e633b8adebc82a2f182f5da6 Sound source choiceFor my listening tests, I've connected the earphones to the following devices.
With Hiby R6, the earphones' sound is a little more bassy and solid. I didn't hear any other difference in the sound of RED when using various sources. Eartip choiceI didn't like the eartips provided.https://preview.redd.it/ibe7nc860v0d1.jpg?width=1800&format=pjpg&auto=webp&s=fbd68bf567e714ad6809423295c8e0b049af3048 Three left pairs have a clearly smaller diameter compared to one of the sound duct and are just difficult to pull on. The right pairs fit the sound ducts easier, but just like the left ones, they're not really soundproof. As for foam eartips, I just don't like them. In short, I tested RED with TRI Clarion, and the same I recommend to you. The fit is comfortable, deep and tight enough. ComparisonsPLEASE NOTE: everything I say below is only applicable to the earphones from the point of view of comparison to other models, nothing more!RED vs. Truthear HEXAThe Truthear x Crinacle ZERO: RED and Truthear HEXA frequency response graphs compared:https://preview.redd.it/690dctkb0v0d1.jpg?width=1600&format=pjpg&auto=webp&s=901456e8b5ae27dfe60ab024099b82a41dd4f49a Subjective difference in sounding
RED vs. Moondrop MayI'd like to note that comparing RED earphones and, in fact, DAP+earphones, which is what May is, is incorrect. Therefore, below we will talk only about the sound. May were connected via their standard DSP cable, and the equalizer was set to 'Standard'.The Truthear x Crinacle ZERO: RED and Moondrop May frequency response graphs compared: https://preview.redd.it/up1nlade0v0d1.jpg?width=1600&format=pjpg&auto=webp&s=10b015a8032de6440aefc8033fde02c579d72268 Subjective difference in sounding
SummaryThe Chinese economic ramp-up, the development of manufacturing technologies for drivers and enclosures, as well as the development of knowledge about sound in in-ear headphones let us buy a product for $55 in 2024, for which sound they would have charged us good $550 without batting an eyelid and turning a hair 10 years ago, although it seems questionable to me that someone would have been up to such tuning at that time.And I'm quite agreeable to give credit to Crinacle: while I honestly wrote in the KZ Zex Pro review that the earphones were frankly poorly tuned (whether through Crinacle's fault or not, I have no idea), RED is a completely different story. This is just an example of how to proceed from competence in the field of headphone measurements to successful headphone production. I am not inclined to believe, of course, that this was a sole effort of Crinacle — everyone sang in harmony, both him and Truthear as the immediate manufacturer. In general, everything is both clear and complicated about RED at the same time: these are earphones with a universal fit and eminently calibrated tuning, combining neutrality, detail, weight, dynamics and lack of listening fatigue in equal measure. Top it off, there is a 10-Ohm attenuator included for those who 'starve for the lower section'. To buy or not to buy: to buy, at least just for the fun of learning what kind of tuning is this! |

2024.05.16 23:26 WobblyGoblin2 How would you attach aluminium trim to this corner?
I have a piece of powder coated aluminium trim that fits this corner perfectly. This ended up being a job I took on as I didn’t want to pay the extortionate amount the windows people wanted to charge. The corner piece is smooth on the inside. submitted by WobblyGoblin2 to DIYUK [link] [comments] My builder suggested expanding foam to insulate and then use Gripfill adhesive to attach the corner trim. I put on the foam and then trimmed it down once set. Used Gripfill - You can see a lot of the blobs of (or where they were attached). The corner seemed solid at first but once the sunny weather arrived a few months later it popped off. Is there a better adhesive to use? Should I use something flexible instead to allow for expansion and contraction with the heat? I’m trying to avoid drilling and using screws to maintain a smooth finish on the outside. |

Hello all! submitted by plsstopprocreating to ArtsyWeirdoPerfume [link] [comments] Feeling accomplished today because I made a custom sized light-blocking panel out of a 1/2" thick foam insulation sheet, and IT WORKED! We're at the part of the year here in Alaska where there's no true "night", the sun sets a little before 11 and then it's twilight for like 6 hours before it rises again. Last year we made do with blackout curtains but they weren't ideal. So I just had my first good night of sleep since I got back from my trip last week 😅 Today I'm wearing Fable & Canon's Eris (Patchouli, vanilla, black pepper, and rosemary) - I have no idea what "popular vanilla and patchouli" fragrance their website is referencing as inspiration for this, since I'm not in the world of mainstream perfumes very much, but I do know that this is lovely! It's warm and spicy but somehow also feels appropriate for springtime. And for a perfume oil, the projection is great! I'd love to hear about something everyone has done that they're proud of recently (if you want to share), as well as what scent y'all are enjoying on this lovely Thursday! |

2024.05.16 18:42 miniheinz [Routine Help] Close Comedones getting worse despite a routine
Hi everyone, submitted by miniheinz to SkincareAddiction [link] [comments] I'm asking for a friend who started her skincare journey last year. She has an oily type, her skin tends to get greasy 3-4 hours after. Her main concerns are the closed comedones, as the skin that gets very greasy and shiny. She tried out a couple of products during the year but stopped later as they had some negative effect on her skin (fatty alcohol, in particular), in March, she started the following routine: AM:
Closed comedones getting worse on the cheeks even if she never had them before there She had them before but they're worse now She decided to pause all the products, and use only cleanser with one of the above-mentioned products. I'm trying to convince her to still use a moisturiser, but the BOJ doesn't seem to work for her as her skin feels very greasy even hours after applying it as if the moisturiser isn't absorbed well. We're based in France, she switched to another cleanser that dries less her face (Caudalie Gelée Nettoyante Purifiante) and to occasional Paula's Choice 2% BHA Liquid Exfoliant. What do you think? Do you have any advice for a greasy type, especially with the closed comedones? Do you know how and why the comedons on the cheeks get so much worse? Thanks in advance!! |

2024.05.16 18:09 pls_send_stick_pics Should I remove or cover?
Previous homeowner put this blue foam insulation over the foundation. The foundation is insulated from the inside as well so I'm not sure it's doing much, home inspector suggested putting siding over top but I'd rather just pull it out. As a bonus it adds a great habitat for rodents to live. We're in southwestern Ontario and our winters are relatively mild. What do you guys think? Junk it or cover it? submitted by pls_send_stick_pics to DIY [link] [comments] |
