Just want to share that for those looking for a pair of great sounding ear buds, the Bang & Olufsen Beoplay EX is imo, the best sounding ear buds for I’ve heard so far. It beats Sony xm4 hands down. The only one that comes close is the new Sennheiser true wireless momentum 3.
For the same price, plus don’t get the Beoplay EQ as the weight of the ear buds are not evenly distributed for long hour listening. You’ll feel the strain after half an hour. The EX which comes with a stem is the one to get because of its design that allows some of the components to be stored within the stem, thereby reducing the bulk. If money is no issue, this is the one to get.
