ISN Audio - EST50

ISN EST50. Good all around fun.

ISN EST50, super fun and engaging, impactful bass with the right tips.

ISN EST50 most musical under 500. Not a Harman + bass clone I've had the Oracle MK1 and Mk3. Bought both used, sold both at a slight loss. Same boring curve. Prestige LTD (makes the target curve worth it with technicalities, staging and timbre), Campfire Bonneville, and I assume the new TA much better but outside your budget.

Well the nature of est iems is that they are pricier than the „usual” BA hybrids, as the drivers themselves are more expensive. When thinking new we are talking 450-550$ at least. Well they may exist a decent set I’m not aware of as I don’t know all iems or even half that are out there, but it is what it is. The EST in it’s character though is worth ot imho, as it sounds way more natural than BA treble or Planar treble. Think DD naturalness yet with way more extension. Then the implementation must be good, as when the iem is not tuned in a way to fully utilise the est potential then there is not really a point to spend extra for them is there. On the cheaper side You have something like: 450$ Sound Rhyme DTE500, a fantatic, warm set with good sparkle. Kiwi EarsxHBB Punch, 400-450$ ( depends if you can get linsoul discount ) latest basscanon from Kiwi and HBB it uses est. Hisenior mega5EST/Mega5est bass+ ( bass+ has nicer treble as welll ). This is a gret choice for most, 550-589 $ I/O VOLARE is at around 600$ has 4 est, very nice set There was also Penon 10th anniversary, but it is no longer being made. 450$ Penon also owns ISN audio and they have ISN EST50, their previous flagship around 420$, but DTE500 is a better choice. I currently own their new flagship the ISN EBC80 2DD 2BA 2EST 2 Bone Conduction drivers set. It’s a fantastic set with a bit large nozzles though, so is not for everyone. And is 699$
