I have a few different IEMS I've been testing with gaming on my PS5 from the budget category I.E. Wan'er, Aria, 7hz Zero. And I have to say these are my favorite so far (Aria Second). If you've happened upon these you've probably heard about their massive sound stage and for the price, it is quite impressive. Good bass but also very defined and separated highs mids and lows where your game (or music) doesn't sound muddy and muffled together. They have definitive directional sound and an airy-ness that really lends to an atmospheric experience. I played with call of duty and could hear clearly where gunshots were coming from. The horizontal Soundstage is bigger than the vertical. But hey. They're 25 bucks. But built quite solid. I also played spiderman with them as an alternative atmosphere and could hear all of the little details in the city. Overall. They are an excellent buy for gaming or music or both. And if you don't like them. Hey, again, $25 bucks. My only caveat is definitely find some more ear tips. Contrary to my former experiences, the foam eartips can make them sound quite piercing at times. Especially with gunshots. The final audio eartips sound quite well. But if you already own the 7hz zero I actually really like the frequencies delivered with the blue or pink eartips that come with the 7hz. Happy gaming. And happy listening friends.

I spent my time with headphones and have recently gotten into more IEMs. It's truly amazing how wonderful these sound at this price. I first listened to them with an iphone, then old android phone and they were so quiet. Stepped up to my portable dac, and still required being turned up to about 75%.Then I finally plugged them into my desktop amp with a balanced cable, they came to life. The speed at the transitions between notes is amazing. I was picking up the little nuances in songs, that I hadn't noticed. Notes didn't hang around anymore, they were just gone when they were supposed to be.They're large and comfortable to an extent, but it depends on ear size. I switched the tips to my new favorite W1s.They're not the best thing since sliced bread, but it depends on what is missing in your collection. I have some that I listen to when I want to have fun. These make me want to relax and listen to songs that I thought I already knew.

The first thing one notices is that these are heavy for their size. The body is made of zinc instead of plastic so there is a considerable amount of mass there. The next thing are the short nozzles which make getting a good fit a real pain. I ended up going with the Sedna Earfit TPS tips. These are $20 for two pair but they will seal at all times. I did have to wrap some tape around the narrow nozzles to get the Sedna tips to stay on. Of course, one usually replaces the cable on inexpensive Chi Fi earbuds. I had a set of Tripowin 16 core silver plated copper and they do sound better than stock cables. They are less tangly, too.As far as sound, they are a bit bass heavy in the lower bass. There is a treble peak at somewhere around 4-6K that is not too bad. The midrange can sound a little sucked out but the resolution and texture is there. Yes, they should be amped. I have a custom Mayflower Cmoy running at 1X gain that is essentially a portable O2. It really tightens things up and focuses the image.I do have a pair of CCA CA16, which I thought were quite good. The Blon do have more lower bass but it is faster. The CCA is quite good in the midrange. The Blon can seem a little sucked out but there is slightly more resolution there. The CA16 are really good up top. Especially since they are a three way system with the fastest drivers up top. The Blons keep up but are not as neutral. I am hoping the top end smooths out as they break in. Imaging goes to the Blons. The CA16s do a great job. The sound stage is wide and pretty well focused. The Blons have the width but added depth. Also, the sound stage is more focused.The CCA CA16are tough to beat. They are twice the price and are fairly neutral. The Blon 01 has a little more zing on the deep bass as well as that treble peak. I am hoping the latter goes away as they break in. We will see. The single driver does produce a more coherent sound and the lack of a crossover is probably why the imaging is this good. For most genres the Blon are pretty clear winners. For orchestral music, it is a tough choice. the Blon is more revealing with better imaging but the CCA are just a bit more natural sounding. BTW, I have the same tips and cable on the CCA CA16.IMHO Blon should go with a plastic body and do something about the short nozzles. That is not much to complain about. So, change the tips, change the cable, and then use an amp. They are pretty incredible then. :-)Update: I used them over the weekend for an extended time plugged directly into my LG phone. Yes, they need an amp. They do sound good directly plugged in but the bass was considerably looser, the midrange seemed rather thin, and the soundstage was good but not great.

Very well balanced across all frequencies. No harsh treble, smooth mids and tight but not overwhelming bass.

If you don't give it power, its very sizzling and hard to listen to. Once you do, most of the sizzles are gone, mids are full and sub bass is clean tight and satisfying. In stock tuning, this thing has deep clean sub bass that's missing on other planars like leshueor S12 or timeless. Those just have boomy annoying mid bass.The midranges are good and very detail, every bit as clean and resolving as more expensive planars. It's also very open and spacious on par with my $1000 akgn5005 amd hifiman Ananda.It sounds less planar sounding than other planars. Give it some EQ to tone down the treble and there's nothing that can touch this for the money.

These KZxHBB PR2s are amazing for their $50 asking price. The planar driver can make sounds you've never heard before in an IEM and are extremely dynamic and fast. It's truly amazing what you can get for <$100 these days in IEMs. There's basically no reason to spend big money on the old school brands (ie: Shure/Etymotics/Ultimate Ears). The biggest con is that you really need a headphone amp to make these buds shine. They have very low, 94dB, sensitivity. So if you just plug them into a USB dongle or straight into a phone or portable audio player you're not going to get much volume out of them. With a decent USB DAC dongle, I had to turn the volume up to 90% to get usable volume. Using my DAC/amp setup, I still need to turn it up to 60-70% whereas most others headphones are down at 40%. If you have the power to drive these properly, they really do shine. If you don't, just skip them as they will be dissappointing.

Excellent!

Wouldn’t be happier with the price I pay for this . Every YouTube reviews of theses were right . Nice bass , confortable and low cost !

No tiene cancelacion de ruido como dice

Son muy buenos audífonos, son cómodos y se escuchan bien. tengo un detalle con ellos y es que en mi teléfono oppo se escuchan bajos y algo diluida la calidad del audio mientras que en otros teléfonos se escuchan muy bien pero el problema supongo que del teléfono. Un detalle un poco molesto es que los audífonos son como anclas, literalmente se anclan a muchas cosas y debes de tenrr cuidado al jalarlos. Fuera de eso por el precio son buenos audífonos.

Anteriormente ya los había comprado, son unos de los mejores IEM que he usado, son especialmente cómodos para mi, como referencia los KZ ZSN PRO X me resultaron muy, muy incómodos, pero estos son otra historia en cuanto a comodidad. el sonido es fantástico, tiene unos graves que llegan a comerse un poco las frecuencias agudas, pero es tolerables. en cuanto a duración, son de zinc y bastante resistentes, mi anterior modelo me duro cerca de 1 año y medio.
