“the Linsoul Zero:2 absolutely shock me at how good they sound driven by my old Samsung Note 9, no dongle, no nothing. I have weird small ear canals for a big guy, and these fit perfectly with the pink tips that came stock on them.”

67% of 97 verified owners recommend the 7Hz Salnotes Zero 2, based on real owner verdicts aggregated from Reddit, enthusiast forums, and YouTube.

“the Linsoul Zero:2 absolutely shock me at how good they sound driven by my old Samsung Note 9, no dongle, no nothing. I have weird small ear canals for a big guy, and these fit perfectly with the pink tips that came stock on them.”
“I was somewhat disappointed with the Zero2. They are decent, but I may have tainted my view by listening to the Castor black for most of the week before I got them.”
“the original Zero is one of the most annoying IEMs I've used when it comes to the tips.”
“is now quite content with the IEM.”
“I have the zero 2's and have to cut 125-250hz by 2 db and boost 8-16k 2 db to get them to sound good. Even then, separation isn't optimal.”
“It seems unneccessarily large/bulky.”
“even compared to the Zero 2s, they do a great job and might even come out ahead depending on your sound preferences”
“Zero 2: slightly better Zero 1 with samey package; $25”
“Still, i prefer the Zero (OG) than Zero 2 but i would choose Hola all the time.”
“I don't get that same lower treble "piercing" sound as I do with Zeros.”
“These are also now my favorite cheap IEM, beating out my previous go to recommendation of the BL-03. They're fantastic.”
“The sound quality is good, perhaps a little too quiet in the mid-range frequencies. Source either a Cowon J3 or Fiio JM21. I mostly prefer the much cheaper KZ -EDX Ultra; they're louder - especially in the mid to high, and sound more open.”
“I have the Zero2 and it's just alright in my opinion. Definitely not bad, but also not as good as a lot of people say. Treble is quite 'metallic' and not very pleasing for my ears. Bass and mids are alright. The cable is absolute trash.”
“returned Hexa and kept zero 2 they are amazing. I want music to sound good & not boring. Hexa's were harsh, then i thought about getting Zero Red but decided to try Zero 2's first & search is over man.”
“The Zero, and Zero2 are a bit hard to fit in my ears, so I didn't get as good an experience, but the eq is still nice, just a bit congested and I didn't get as much detail from them.”
“it sounded completely different once I use foam tips in my OG Salnote Zero, the bass actually better and treble is tolerable”
“Decided to get the gate because wasn't a fan of the color eartips and wire”
“I just got zero2, cadenza and caster bass edition; I definitely love the caster for how bassy it is and the former two is quite decent on the bass while being more balanced.”
“Recently bought the Zero 2 and Ziigaat Nuo and they both are great for $20, albeit a different sound signature. Unbelievable how cheap these iems are for its performance.”
“Crin's collabs are really lacking lately.”
“The Zero2 is a very competitive IEM for being only $20. What the EW300 does great is taking that same awesome W sound signature and stretching it to a nice wide soundstage.”
“I have recently bought an iem earphone (7hz salnotes zero 2) which had cost me around 1800rs. After receiving the product i noticed that the mic wasn't working at all.”
“It is V-shaped. Unfortunately for me, it does not fit into my narrow ear canal... so I had to return them. But, despite not being able to make a good seal in my ears, I still liked the sound.”
“Today I'm with the Zero 2. With the FX9 tips , and Crins Bruel & Kjaer EQ preset, they deliver a sound at the highest level!”
Practical notes owners raise — setup, quirks, and issues to watch for. They don't say whether the person likes the product, so they're not counted in the score, but they inform the pros, cons, and who it's for.
“Looks like the pre-installed tips (red) are the 2nd largest in the box, they are a little small so the seal is not great, but the largest (yellow) are too big, never had this problem before with the original 7hz zero”
“Audio quality is great for a 1st time iem user, only issue is comfort due to iem shape / ear tips.”
