The LEAR Kaleido is a great IEM. Suitable for mini audiophiles, high enders who want a chilled vibe session and also the more profane mobile phone users.
Easy to drive, nary a hiss and a satisfying black background.
I found the fit easy, light and comfortable.
JVC Spiral Dots are my usual go to tips for fit and preferred sound signature, I found the stock tips comfortable and well fitting, I ended up using the black silicone the most.
The Kaleido leans towards the warm side of things, its very forgiving, smooth and velvety.
Dap matchability is a must, I enjoyed it with Opus#2 (most recent firmware) , iBasso DX200 with amps 1 & 4 (with ALO Audio cable and iBasso adapter) and the Hidizs AP80 for instance.
I found a brighter dap such as the Opus#3 gave the treble more presence and also lent more towards a V shape. I would recommend a neutral or near neutral dap as a complimentary pairing, but we all have different ears ;)
Daps aside I tried it also with my ipod Touch 6G (using Flacplayer app by Dan Leehr), whilst it performed well with dedicated daps I could detect less resolution, graininess and a more compressed sound stage on various tracks when used with the ipod touch 6G.
Perhaps some of the more recent phones with their high end dacs might be more of a pleasing experience and combination.
The LEAR Kaleido has more of a chance to shine when combined with a decent dap.
In closing the LEAR Kaleido is an earphone that can be pleasing for many a casual user I would expect. There is nothing terribly offensive about the sound, no sibilance or screeching highs, no flabby or overpowering bass, enough mids to give the vocals that swing but without entering into muddiness.
It is an earphone that is lovely to look at, small enough to fit most ears well, has an engaging sound which is coherent and performs great when paired with a decent source.
