7Hz - Timeless

Of this list, my pick would be the S12 Pros. They can do the ethereal and detailed sound for things like small ensemble jazz or classical and then crank it up to 10 for harder metal and rock styles with equal aplomb. The S12 series have been my favorite ever since the introduction of the OG S12s which quickly replaced my OG Timeless. In the years since I've owned or tried most of the major players in the planar market and they have remained my favorite single planar until you get to the CFA Supermoons.

Timeless 7Hz. Anyone else or are these too old or surpassed now?

Timeless 7Hz is great for classical.

My first pair was some Fiio pair (o think the F3?) that everyone raved about for gaming and sound quality compared to how cheap it was....was one of THE WORST sounding hollow tin pieces of shit ive ever heard lol. I swore off all IEMs after that thinking they could never compete with "real headphones" but then I got pretty damn lucky; there was a pricing error on Amazon and I bought 2 pairs of EW300 DSP for me and my ex for $8 each (was supposed to be $80) and damn were they actually pretty fucking close, just had weird highs that I started hearing and didnt like them after 5 months, so I gave them to my niece and bought myself a used pair of 7Hz timeless and just cleaned them, absolutely my favorites so far. I fear this new hobby of mine is going to cost me more than my ex ever did, which she made off with $1000s worth of shit. Oh well I got better headphones/earbuds now 1 point for me; 3450 for her

The first wave of well-tuned planars (Timeless/S12/etc). That level of technical performance for 200 bucks (or less) was (and still kinda is) insane.

> The s12 pro are still fantastic in my books. Yeah, it and Timeless broke the meta for a good reason. Roll the clock back to 2020; good tuning was already widespread, but anything technical was >$300 for the very best stuff (like Blessing 2) and >$500 on average.

It'll be a tie between blon bl03 and Timeless. Blon because it scales well, takes EQ like a champ and has a soft, "glowy" mids. And Timeless because it sounds detailed and effortless.

My 7hz Timeless for example does in my opinion sound better than my Sennheiser Momentum 4 for example, so I can kinda agree. The same Sennheiser Momentum 4 in my opinion does not sound as good as the Fiio FT1 Pro that is half price. So it's swing and roundabouts

Knowing your recommendations here, do you have any experience with the 7hz Timeless. I have them and I like the bass on them (once I EQ a bass bump into them) but Ive read a lot of ppl saying they’re disappointed by the bass and Im wondering what something better would sound like. Im wondering how they compare to what youve mentioned above because I def like bass but Ive been underwhelmed by the Zero Blue 2s (rather fatigue-ing).

I have the s08 and the s12 pro. I like the s12 pro, they sound very similar to the 7hz Timeless, and the Timeless are one of my favorite headphones of all the ones I own. I haven’t heard the MP145, but they are supposed to be incredible if they fit. The normal T10 is an amazing value. I’m not sure how good the T10 Pro are, but if you want value, the T10 is the way.

I was from Aria -> Timeless -> Supermix 4, and so far i’ve been liking the Supermix 4 when I changed the tips to Tangzu Sancai. Dy think Tea Pro/Odyssey is a worth upgrade / worth buying? Im tryna find my endgame, and Tea Pro actually looks intriguing to me.. what are your thoughts?

I wouldn't list the QKZ Hades, as it's pretty universally hated, unless you specifically mention that it's a *very* niche tuning most people don't like (even most bassheads). And even among people who like it at all, it's generally a one-genre set. I'd strike the Juzear Clear off the list because it appears to have [really bad unit variance](https://old.reddit.com/r/iems/comments/1insj4z/some_thoughts_on_the_juzear_clear_and_myer_audio/). I still recommend it for the cable if it's on sale for $20, but only if you really want that cable (it normally costs about $15-20 on its own). It's not a highly recommended IEM anyway, it just had a brief period of hype as a basshead IEM. Rarely gets mentioned nowadays. Neither of my two units are true basshead sets (and one is quite bright), so clearly some golden units went out to reviewers. The Blon BL03 ii hasn't got particularly good reviews. It seems to be that if you care about tuning, the original is better. The new one has 2-pin but it has all the ergonomic problems that plagued the original, so I don't think it should be recommended at all, with maybe a nod to the original as being a classic if people are able to pick one up cheaply. I don't think the KBear KB02 is worth recommending unless you specifically want to know what a BC driver does, in which case it's the cheapest way to get one. I got one for that reason. It sounds pretty bad. All the reviews point out the same issue - there's some weird "springy" resonances, especially noticeable with spoken word. It also makes everything sound like you're listening through a cardboard tube. It's just weird, not good. Audio Amigo and Paul Wasabii both have good reviews btw, I agree with pretty much everything they say about them. I don't see the Tin Hifi C2 mentioned on your original list or the new one. That's a 2025 version out recently. I have both and they are both excellent. Lots of reviews out there, but fewer for the 2025 version. I'm not sure if the old one is being discontinued, but it seems to be still for sale for about $20 while the new one is closer to $40. The difference between the two versions is quite subtle. The Moondrop Starfield 2 got pretty universally terrible reviews. The Juzear 41t and the Flame are the same IEM, so I'd put them on the same line - the flame just has a different faceplate. I have the 41t and it's good aside from the annoyingly bad venting, but I'm hesitant about recommending it for the reasons mentioned in my post about the Clear. Since it's a hybrid it really *should* be fully vented and I now consider this an engineering flaw rather than "just the way it is". Every other manufacturer seems to be able to vent their hybrid IEMs properly. The 7Hz Timeless probably shouldn't be on the list because it's very outdated nowadays. It's only a classic because it was the first reasonably-tuned planar, not because it's good by current standards. It was still an early and not-very-refined version of a formula that's been iterated on continually since then. The AE is better but less widely reviewed. The 2 seems to be getting good reviews but I believe it's closer to $300.

There's quite a broad range. For example: * Aful MagicOne - pretty, but not overdone * Ikko OH10 - good looking, nature-based & reserved * 7Hz Timeless, Timeless AE, Simgot EA500 - minimalist * Tin C2, Dunu Titan S (black/red version), Truthear Hexa/Pure - industrial There's a whole load in the middle that are just random swirly colours which has become the default low-effort design. Something like the Thieaudio Legacy 2 does that well IMO because its just one colour with a bit of texture, not all the colours, all at once. If you want a plain black cable, look at the KBear ST12. There's lots of options out there. I notice the stock cables often don't match the IEMs very well, and intentionally or not, this most likely helps sell a lot of aftermarket cables.
