I bought them for commuting and traveling light with good sound quality, and so far they deliver. Sound is kind of V-shaped with elevated bass; it has been well described elsewhere (the original Shure SE215 with no phone controls is kind of a classic, look for Tyll Herstens' review and measurements). Sound isolation is good, though not great for traveling these days when buses/airplanes have noisy air filters working. The cable somewhat stiff and can be a bit annoying from the L/R joint upwards, but is also robust at the plug and earpiece ends which is reassuring. Build quality in general looks good, and the replaceability of cable and tips is something I value. Also, nice case and eartips of different sizes come in the package. Confort is good, but it took me a while to get used to the fit and learn to put them right. Be sure to get a proper insertion for tight fit and good bass in the sound. For the price this is a solid choice and I would buy it again. Oh! And thanks for the nice sales support at Thomann :)
