QKZ x HBB

Your Sony were 10Ohm, Zeros are 16Ohm so there should be a difference with a same source. Zeros are known to be uncomfortable based on your ear canals size. Don't hesitate to return them. For the price get a cheap dac (like 8 dollars) from AliExpress and get iems with standard bore size. There are good entry-level bass oriented iems like the Qkz x HBB Hades or 7Hz Legato. or even KZ castor bass pro

Most of these give me the warm + bassy vibe, some are way more bassier than others & some are more darker or brighter than others in tuning but none are what i personally would consider bright, sharp or piercing in the highs. 1. 7Hz Legato 2. Kbear Rosefinch 3. Tangzu Fudu Verse I 4. Kiwi Ears Melody 5. Kefine Delci 6. Truthear Zero Red 7. Tripowin x HBB Mele 8. QKZ x HBB 9. 7Hz x HBB Elua 10. 7Hz Zero 2 11. Kiwi Ears Cadenza 12. Kefine Klean 13. Kiwi Ears Dolce My Personal favorites are the QKZ x HBB, Rosefinch, Legato & Delci as I can crank them all the way up without treble fatigue, the Rosefinch & Legato arguably have the most sub-bass rumble on this whole list with slightly darker tuning, the Cadenza & Delci are slightly more balanced bassy sets with warmer, lusher sound i would describe

my favorite is the QKZ x HBB but its more so because its the first iem i listened to that had the sound signature i was looking for which is warm, smooth treble + thick or meaty sub-bass thump & rumble. Ironically its my most favorite set even with the more expensive sets i own maybe because of sentimental reasons but i still keep it in my collection because the tuning is my personal baseline for what sound im looking for. then i would say the 7Hz Legato would be my 2nd favorite as it has this bassy club like bass i never really cared for EDM or Electronic music until i got these, i understood what reviews meant when they described it as "A Wall of Bass" when i bought them they are basically are a more bassy more detailed & cleaner sounding Kbear Rosefinch which is already a bass cannon set in its own right both are warm but i would say they lean just slightly in the darker tuning. then you got the more expensive heavy hitters, TSMR Armor, Ziigaat Doscinco, Fatfreq Deuce, Punch Audio Portazo & Martillo. the TSMR Armor is what i would describe as a more refined/detailed QKZ x HBB with even more meaty & punchy bass in the UDD switch config. the Punch Audio Portazo to me sounded better than the Martillo as i already owned the Deuce and i couldnt justify the price tag of the martillo for cleaner sound as i bought the Deuce & QKZ Hades strictly for insane amounts of sub-bass for guilty basshead pleasure, the Portazo just has a harder mid-bass punch than the Martillo with brighter but not harsh,sharp or shouty treble to me its the better value, the Ziigaat Doscinco is what i would call warm, lush sound with mature tight bass i liked the sound of them but ultimately returned same reason as the martillo the value to bass performance for me wasnt there but i see why many people love them. lastly the Fatfreq Deuce my guilty pleasure bass cannons set, these are not warm but just like the Portazo they are not really bright either in the sense of being harsh or shouty in the highs if you are chasing sub-bass rumble and something like the Rosefinch or Legato didnt scratch the itch enough or cant justify the price tag of the Fatfreq Scarlet Mini or Grand Maestro then you have the Deuce i compare the amount of bass on them to the QKZ x HBB Hades which has been discontinued but much much cleaner sounding whereas the bass on the Hades sounded muddy, cheap and the vocals were recessed to the point they sounded underwater, the deuce just make me smile when i play hip-hop and EDM they are what some might call one trick pony but as a basshead they do the trick very very well and they finally scratched my itch because of them i now kinda stop going after more expensive bass heavy sets like the Kiwi Ears Punch or Ziigaat Arete 2 and turned more towards sets that are unique, weird or lesser known to keep adding to my bass collection as the deuce are pretty much my endgame set as a basshead lover.

Here are some recommendations under $50 or can be found most of the time under $50. KBear Rosefinch 7hz Elua (not ultra version) QKZ HBB Hades (you say you don't care about details, stage etc but you may regret your words after hearing this.) 7hz Legato (if you can stretch like $10, this one has the most dynamic and engaging bass among my recs.)

Hades makes every other cheap basshead set feel like God's grace. Take any other basshead set and do you think it's muddy, bad vocals, has no mid, treble, stage, resolution etc? Hades will make you eat your words. It has extremely stupid amount of bass with no texture, it's dark, overly muddy, boomy, congested. Legato bass has texture, hits very hard and pleasant. Other frequencies are very acceptable for the final purpose. I have seen reputable reviewers criticizing Legato with vocals etc but personally I find those takes immature and ignorant of its purpose. It wasn't tuned as a pure basshead set only but trying to give the feeling of old, classic subwoofer sets. And it succeeds very much if you ever have been familiar with that sound. (that might give ideas about your age also.)

As bassy as Rosefinch? sadly none, if you can wait for a Sale, QuietSea II (which is $70 stock). We bassheads really are starving out here in the $50 price range. Now, if you want only bass, no exageration, like literally only bass, consider QKZxHBB Hades.

I have the Rosefinch, Legato, and Hades. The Hades sucks. I mean I think it *technically* it has the most bass but it's not as good as the other two imo I've been eyeing the Diablo and Armor for my next basshead step up
