      Budget Beauties

      Timely delivery and great customer service from Hifinage.com. Looking forward to buying more stuff from them.

      First impressions: A lot of people suggested wide bore tips for this. Tried stock tips, it sounded below average, muddy. Tried wide bore and the highs were gone, it was a mid-bass massacre. After an hour of replacing tips, tried the double-flanged one and voila. Tight controlled bass, minimal mid-bass bleed and focussed mid-range with a slightly harsh upper mid to lower treble (totally acceptable).

      The low extension is fantastic, in addition to my reg music tried some movie trailers as well. Blasts, rumbles sounds fantastic with good depth but surprisingly recovers very quick as well. Checked with some electronic music like Dzihan and Kamien, plaster as well. Sounds very good. With any other tip except the double-flanged one, it reaches basshead levels which I personally never enjoy.

      Mids are recessed yes but have good tonality and attack. Metal guitars(Dying Fetus, Cannibal Corpse, Krisiun, Origin) sounds very realistic with slight grain which I like. Softer albums like Seachange (Beck) sounds acceptable.

      Highs are a little limited and tamed. Make no mistakes with the double flanged tip it gets very bright but still a bit limited and stiff(extension wise). Some track shows a slight hint of sibilance here and there but that’s nitpicking.

      Sound isolation is extremely spot-on as it fits perfectly in my ears. It’s light, comfortable for long listening sessions.

      The soundstage is decently wide horizontally but a little less vertically. Overall the 3-dimensional presentation is satisfactory.

      Imaging is good overall, separation is decent too.

      Extremely sensitive to tips. Never heard such a huge difference with different tips with any other earphones.

      I don’t wanna comment about cable quality etc at this price point. Removable 2 pin cable is provided whereas my one more triple doesn’t come with one(and costs almost 3.5 times).

      What a value for money. What a great time to be alive.
