Linsoul 7Hz x Crinacle Zero:2 In Ear Monitor, Updated 10mm Dynamic Driver IEM, Wired Earbuds Earphones, Gaming Earbuds, with OFC IEM Cable for Musician (Orange)

Simply outstanding, even better with a wireless adapter
This is a review for a combination of two products: the 7Hz X Crinacle Zero:2 paired with the TRN BT20 Pro – combined these two create a True Wireless (TWS) pair of headphones for under £50 total. Individually, both products will typically sell for £25 or less. I purchased these both as my first set of wireless buds but also to allow me to have replaceable wireless adapters in the event of battery failure or equipment damage. I would have preferred a product with replaceable batteries but these currently do not exist.The 7Hz X Crinacle Zero:2 has quickly gained fame as the second revision of a very high quality set of wired in-ear monitors (IEMs) for £25, considered the ultrabudget price bracket. There had to be some concessions at this low price point and unfortunately the sticking point for most people will be the provided removeable cable. For those unaware, the most common point of failure on an IEM is the cable, so being able to replace a damaged cable on an otherwise working product is very welcome and cuts down heavily on waste. Unfortunately the provided 0.78mm 2PIN cable is adequate in terms of sound quality but very tight on the connector – you will likely feel you’re going to break the connector when initially inserting them. Once on however, the cable is held securely and is functional, if a bit spartan. Most people are probably going to want to replace the cable, and the Tripowin Zonie is an easy choice for this – make sure you get the 0.78mm 2PIN version if you do this.The provided tips were not tested, but match the previous Zero’s tips, which I have tested in the past. These tips are functional, and if they work for you there’s no need to look further afield. I, unfortunately, have very fussy ears that require specific tips. Fortunately I already had access to a spare pair so I simply used those instead. I had no issues whatsoever with fit with these IEMs, so it seems the 7Hz nozzle shape particularly agrees with me as I also had similarly few problems using the much more expensive 7Hz Timeless with a similar nozzle structure. Some people have reported problems wearing these IEMs due to their ear shape, however, so you may need to consider a different product if these are a bad fit for you.While I was waiting for my wireless adapters to be shipped I tried the product wired with an alternative cable and tips. It has to be said – the sound quality of these £25 IEMs is audiophile-grade beyond all doubt. If you have ever wondered what music and audio is supposed to sound like, these gems will tell you all you need to know. Clearly all the budget went into the drivers. They are particularly good at reproducing midrange tone and timbre in a way that much more expensive products often struggle with, so most anything you play on these will simply sound correct and accurate. This would be remarkable at any price – at £25 now there’s no excuse – this is a PHENOMENAL quality floor to start from and everyone should try these at least once. It almost feels insulting to limit them to a lossy Bluetooth codec like I have! They also EQ like champions if you’re still not satisfied, although I find a very subtle EQ is all that is required to suit my personal taste on these.However, they aren’t perfect. While the Zero:2 has no problem reproducing any audible frequency well in isolation, from the lowest 20Hz thumps all the way to 20KHz (20000Hz) mosquito buzzes, reproducing them all at once as with regular use listening to music exposes some mechanical limitations of using a single tiny driver to do everything on its own – in this situation the low-end and high-end each get muted compared to how they should sound. They do not sound muffled, however – merely quieter than they should be in theory and very much still audible! You will hear clear meaty subwoofer-style thumps from these IEMs, you will hear intricate breathy high notes from these IEMs, but if you play a complex track with everything at once the midrange gets pulled forward very noticeably as the driver simply can’t reproduce it all fast enough. This is still a dramatically better handling of a driver’s shortcomings than with lesser products, so don’t misunderstand – this is as graceful and distortion-free a handling of an overextended driver that you could ever encounter, and many of you might actually prefer a midrange emphasis anyway. It does mean, then, that there is room for improvement in much more expensive products – but not a lot! Most people reading this will be happy to stop with these, unless you particularly dislike a netural sound signature (where nothing is boosted nor surpressed in the mix).As a paired unit, the Zero:2 and BT20s work very well together overall, and over time this turned out to be a bit of a fluke. I keep finding that the left adapter slips slightly on the 2PIN connection when in use, exposing the pins by a millimetre, but this is easily checked for and corrected and did not affect the connection or sound quality in practice. I suspect this is more a problem with the Zero:2 than the adapters however and explains why the cable supplied with the Zero:2 is so stiff, but it’s worth noting nevertheless.Ultimately, I consider this experiment a success. The 7Hz X Crinacle Zero:2 is a fantastic IEM, let alone a fantastic ultrabudget IEM, and you are highly likely to have an excellent time with it. If you want to go wireless with it, the TRN BT20 Pro is at the time of writing one of the few choices available to let you do so and is very affordable as well. They make a good, if not perfect, pairing and I am likely to get a lot of use out of these two!

Solid Choice
Sound quality is great, miles ahead of pack in ear buds, and in fact better than some IEMs at a higher price level. Good bass, including sub bass, without it being overwhelming or muddy, nice detail, can really make out the bass guitar parts on some records for example which cheap earphones struggle with, sweeping guitar riffs sound lovely.Can’t comment on longevity as I’ve only just received them, but I’ve received other cheap IEMs that were DOA so they’re winning on that front. Cable is fairly cheap but it’s a) removable and b) a cheap set so. You can always replace with another cable but you’ll probably find a replacement cable is the same price as the IEMs themselves.Soundstage is impressive too, I use them while playing Switch and the spatial sound is great, especially in eg Dragons Dogma, Skyrim.Comes with a solid array of tips too, not just S/M/L but in-between sizes too. I’ve had no issue with fit and they seal well, nothing falling out if I shake my head.Of course they’re £20 IEMs so they won’t stand up to a £120 pair of Sennheisers, but they’re a really solid choice, just wouldn’t buy them if you need something that you can expect to stand up to a couple years of use. The sound quality is ahead of the price, but the build quality is firmly the price they are, that’s the price you pay. I would pick these over a £30 set of more well-known brands, which I’ve had fail on me too.

Good sound quality, but broke after a month
Right headphone blew after 1 month, just after the return period, good quality sound but did not last very long whatsoever

Excellent son à un prix plus que raisonnable.

Graves bem definidos, embora precisem de um reforço na equalização. Médios e agudos bem muito bons
