Then probably have less distortion than most earbuds in this price range which is what makes them appealing, there faults are faults of omission rather than added  sizzle distortion or exaggeration...the upper register is somewhat veiled but appealing and acceptable considering the price, the lower end is also not as well defined as some more expensive ear buds would be but acceptable... Don't expect these ear buds to compete against Klipsch Image S-4 buds or Sennheiser IE-4's...but in this price range you could do worse a lot worse...
