TANCHJIM - One (USB-C)

All of the above have emphasized bass (more than neutral) to varying degrees, I would recommend something like Tanchjim Bunny, Tanchjim Zero Ultima, Tanchjim 1, Zero 1. (Tanchjim is the only - or one of the few - IEM companies that makes more neutral signatures at the sub 30 price range.

The Simgot metal 1DDs are all very comfortable. You have the EA500LM for a balanced, but somewhat aggressive v-shape, the original EA500 that's very bright and gets fatiguing quickly, but it probably has the biggest wow factor for the price. And the EA1000 might be just in your budget depending on sales/offers and is sort of a more refined EA500 that isn't as bright or fatiguing. The EA1000 is my overall favourite IEM, but the EA500LM is possibly a safer option for more people as it's the bassiest one, and although it also has more treble than the OG EA500, it's more balanced out by the bass and it doesn't sound as bright. The other notably good 1DDs are the Tanchjim ones, but their ergonomics are terrible. They're small, but have very bad fit stability. Also the Moondrop Kato, if you can find one, is a great all-rounder 1DD and very comfortable. But it's discontinued. The Kefine Delci is really comfortable, but it's a warm, laid back sort of tuning that's not really competitive with the $100+ stuff when it comes to resolution etc. If detail is your top priority, you aren't going to beat the EA1000. Also while it doesn't have as much bass as the EA500LM, it has more "kick" to it than any other IEM I've heard, and it is very *realistic* sounding bass, especially for acoustic drums.

tanchjin ONES are great! love that they are bullets with 2 pin connectors

tanchjim's dsp is peak, the bunny itself is very normal

just get the dsp, it's not a big difference in price and eq in what you want. the bunnys are very very responsive to eq, in a good way

no, tanchjim bunny\\one made it obsolete
