r/iemsBest Budget IEMs For Valorant
3 months ago

im currently using blon bl03 version 1 , which is good for valorant but not perfect one. actually what i come to know that every person has its own sound taste regarding his capability of listening , some love bass some hate , some love treble some hates. so i concluded that before buying a new iems just give a 30% conclusion on reviews, 30% on graphs and rest is your risk of buying new iems. but look at graph first and analyze that are you a bass guy or treble guy or if you buying for gaming then you need good treble and good mids and a slightly bass and a best proper sound staging helps directional sounds so keep these things in your mind and you are good to go. and 1 thing more i will definetly give a try to em6l than supermix 4 heard that supermix 4 sound staging is somehow become harsh when sudden frags and guns fires sounds collectively coming from same direction on in team fight supermix 4 become harsh which effect sound staging.

BLON BL-O3 would suit your purposes nicely. I bought one a while back and was very pleasantly surprised. It punches well above its price. Good luck with your search.

Admittedly from Chifi - got into them during E1001, Whizzer, KZ ZS days and started going down the rabbit hole of "oh this sounds rich, that sounds smooth this neutral that soundstage". 15-20 pairs in, I just got tired of 'chasing' the best sound for the best price because there is always something new and new =/= better. I also worked through dozens of DAC dongles and finally just went TWS for practicality. In hindsight, nothing got me feeling as pleased as my bl03 with foam tips. They sure aren't the the universal best, but to me the sound was so smooth and relaxing. Occassionally I take them out and listen to them at home. But when I'm out and about, I just use my Nothing Ears. But secretly waiting for them to die on me so I can justify a pair of Technics. By the way it's like this with a lot of different hobbies. It's a tiresome cycle but the joys must be worth it for people to do it over n over.

r/iemsWan’er S.G’s I don’t get the hype
11 months ago

Not really in order, as different tunings: * Moondrop Chu 2 - mild v-shape, great IEM * QKZ HBB - warm/bassy, great IEM * Blon BL03 - fun v-shape (but the fit is terrible) Bright neutral has a few options - I prefer the original Chu but the crappy fixed cable lets it down. The 7Hz Zero is a bit better in that regard, but I don't think it sounds quite as good. Arguably it's better to pay the extra for the Moondrop LAN for this signature because it's the best one until you go up significantly, but OTOH it's also kind of overpriced for what it is (I think it's around $40 normally, but it's basically just a Chu 2 with less bass). The 7Hz Zero 2 is OK as well but I personally find it a bit of an overly safe middle ground between other, better IEMs. Like the QKZ HBB, if you want warm but don't want to go quite that warm. It's probably the one that's the closest competitor to the Wan'er, as a better all-rounder. Although I find the Wan'er has a stand-out feature in its vocals while being weaker elsewhere, but the Zero 2 doesn't have a single stand-out thing it does better than anything else. It could maybe get the award for the okayest $20 IEM, as it doesn't do anything bad, but nothing stands out as particularly good either. You also have things like the KZ EDC Pro as probably the best beginner IEM, for around $5. It's very close to the Chu 2 but a bit bassier and slightly less refined in the treble. Probably more comfortable than the Chu 2 and less prone to condensation issues. The KZ Castor Bass, around $15, is good for a really hard-hitting bass tuning, although it's not an all-rounder and the tuning is a bit grainy.

r/iemsConfused between blon blo3-ii or blon blo3. Please help
3 months ago

Both have a weird fit, so probably aren't the best buy nowadays. It has trouble staying in the ear because of its shape. The new one has a less weird connector for the cable, which is a good thing. However, they made the tuning worse, so it's not really an IEM anyone recommends. It's pretty meh for the price range and you still have the problems with the weird fit. The original BL03 is a bit of a classic and still holds up for how it sounds, if you want a fun-sounding but competent IEM with good bass and reasonable technicalities. However the stock cable is crap and the weird connector makes it awkward to get a replacement. It's TFZ, but even TFZ cables don't fit perfectly because they made it nonstandard. They fit securely, but there's a gap that doesn't look quite right. I would suggest instead looking at something like the KBear KB01, which is around the same price and is a better IEM overall. Not exactly the same tuning, but it still has decent bass and an overall balanced tuning that works for most music. When you get your phone without an audio jack, buy a dongle DAC at that time. For Apple, you may want to stick with the Apple dongle. For Android, the JCally JM6 Pro is the most recommended. This also has a bit more power, which you won't need for these, but might be useful in the future if you get something else that's harder to drive.

Blon BL-03, and no but that thing was my work horse for years.

r/iemsHow much do I need to spend so my iem doesn't sound cheap?

The cheapest I have are the Blon bl03 ($30) and they sound great.

r/iemsI'm an IEMs absolute noob, and I wanted to give them a try. What was your first IEMs? Do you regret it? What would you get as a first cheap one if you could do it again?
4 months ago

My first was the original Blon. No I don't regret it, I still have it. It served me well for a few years. Knowing what I know now, I'd go straight for an endgame set and call it a day. But, if I also wanted a sub $100 set, I'd go for either the Juzear Defiant or Ew300.

Blon BL-03 was my first real introduction and the only thing I regret is letting the hobbyist and collector mindset consume me. I now have too many IEMs and too little money!

r/iemsAre IEMs really good for gaming? I have a doubt.
9 months ago

I do not play games online. Mine are all single player games and my Blon bl03i/bl03ii has been phenomenal for gaming.

r/iemsWhat was your first experience with more expensive IEMs like?
6 months ago

My journey was something like this: Got Hifiman Re400 Waterline back in 2016. It was neutral. Loved it. One year after the cable insulation fell apart. Audio Technica IM70. Harder hitting bass. Highs were a little subdued. Used it for 2 years. Then the cable connector stopped working and I couldn't find a cable replacement as connector was proprietary. Asked a friend to get me Ibasso IT01 from US in 2019. I do not remember much about its sound. But the connector was mmcx and it sucks. One of the earpiece ended up with a loose connection. Between 2019 and 2021, I got Dunu Dk2001, Obravo Cupids and Bravado. Liked them, specifically Bravado and Dunu. But Bravado had driver flex and it was very bad in that aspect. Sold all of them off. End of 2021 after Covid restrictions were lifted in my country, I had switched jobs and I was looking for some better iems (I could invest some more money into them). Fortunate meeting with a dude (who turned out to be a very good friend later on) made me experience some iems and those blew my mind. And luckily for me, he was looking to sell all of his iems as he was in need of money. Inear PP8. Blew me away. I bought it off him. Then Oriolus MK2 (bought it for my then gf and now wife), Oriolus Mellianus (detail monster without being harsh). Pears SH3. I understood with SH3, it is the tuning that matters and not the number of drivers. Bought both Mellianus and SH3 from him. And all at very good prices. All of this was between 2021 and 2022. Starting 2022, I got a few more iems. Oriolus Isabella. Such beautiful mids. I eqed the lowend. Gave me a lot of joy. Next was Oriolus Szalayi. I was looking for an iem pair with heavy lowend. Sza delivered. It is still my favorite pair. With Isa, I started on the single dd path. I got FAudio Dark Sky next. Wonderful sound. Then I had a chance to buy Inear SD5 wooden shell. Loved it too. Thicker lowend than PP8, but PP8 was still better as an alrounder. I got Letshouer S12 and liked it but the upper mids sounded harsh to me. I changed the cable to one with a mic and it is relegated as my calling iem. I was looking for a cheap but good iem pair that I can use while travelling. Bought Juzzear 61T. Liked it a lot as it has very good lows and mids and highs were good too. My wife liked how it looked and sounded and thus it became her iem. She has two now. Last year I bought both Blon BL03 i and ii for regular use, and they still are my daily driver. And with this I was all done with my iems. I got out. Start of this ear, I started looking into flathead earbuds. Started with VE Monks lite. Then got for myself the Fiio cheap flathead pair. Then two of the Faaeal earbuds and Ry4s. I will get one last earbuds pair sometime later and then drop out. During Corona, I was stuck at my hometown and since I packed lightly hoping that I will be back for work, I packed lightly. But alas, I was stuck at my home for about 2 years without my dap and iem. So, what I have done now is, I have kept most of my favourite iems back at hometown in my room. Rest are with me. This way no matter what and where, I just need to carry my dap and I will always have iems to listen to music.
