If you want to unscrew your audiophile requirements on the road and in sports, you should look at the E1010 of 1more.
With a high demand, 1more is approaching its cable-bound in-ear tip model E1010: the Quad-Driver capsules are made of aluminum and work with one carbody driver and three additional mounted miniature mid-tweeters that offer a frequency response up to 40 kHz , In addition to this are kevlar-coated, oxygen-poor copper cables, a speakerphone and metal reinforcements at all mechanically susceptible positions. The manufacturer also won the grammy-award-winning sound engineer Luca Bignardi.
In addition to a high-quality package, a leather carrying case, 6,3 mm and an aerial adapter and a fastening clip, I find the tangle-free cable, the robust yet lightweight capsules, connections and controls as well as the hands-free system High level of language intelligibility. It is by no means a matter of course that the choice of nine ear pieces is lavish. Ultimately, these have a significant impact on sound quality.
The wearing comfort is high, because the well-fitting aluminum capsules are light enough for the continuous operation. Personally, with me a somewhat more compact design would have improved the seat still somewhat. The sound insulation from and to the outside is also very good. Ultimately, of course, the sound counts. Again, the E1010 does not allow any weakness and sounds balanced and unstrained over the entire frequency response. In the heights, the drivers offer excellent transparency and resolution, which means that the finest details, the room and, in particular, the stereopanorama are accurately imaged and fanned out. Harsch never sounds, unless the source material has corresponding deficits. The midrange also convinces with its detailed resolution, openness and realistic fundamental sound.
The E1010 is defined in the bass section. Deep frequencies are reproduced tonally and without gums, at the same time never overburdened. As there is no lack of pressure, the fun of listening is not too short. Only a little extra bass I would have liked.
