    Customers like the comfort of the headphones. They mention that they are a solid pair of comfortable ear buds, that stay in place and do not hurt when they lay on their side in bed.

    Customers are mixed about the performance of the headphones. Some mention that they have performed well, the subsystem is very good, and the bass is coming through and becoming more powerful. They are perfectly fine for lifting and body exercises, and they are perfect for running. Others say that they stopped working after only using them for not even 5 months, the right side speaker does not work, and that the earbuds finally died in early February 2016. The bass response, which is slightly over-powered, is enjoyable depending on the occasion.

    Customers are mixed about the fit of the headphones. Some mention that the package ear pieces were the perfect fit, while others say that they don't hear right, definitively not the right fit, and the buds are a bit too long.

    "...They make a nice tight fit in your ear canal and only after very extended periods will you notice them at all...." Read more

    "...Length:It's pretty long, but most headphone wires are too long. I just tuck the extra wire into my pocket if it bothers me...." Read more

    Customers have mixed opinions about the appearance of the headphones. Some mention that it is a great design, while others say that it has an odd look. The asymmetrical design is unique and provides a unique noise-canceling design. However, some customers also say that the design is flawed and boring, or even cheap.

    "...The asymmetrical design also is much better than I thought at first, it actually makes the cord much more manageable since the right ear's cord goes..." Read more

    455 customers mention72 positive383 negative

    Customers have negative opinions about the cord length of the headphones. They mention that the asymmetric cord lengths are weird at first, and the left cable is a tad short. They complain about the two different cable lengths between the earbuds, which can make it difficult to manage. Some customers also mention that it can catch on their collar and pull on the shorter left cord, which is bearing all the weight.

    "...First Impressions:"Huh, the right chord is long... huh? Ohhhhh, i get it." It something how it went when i pulled them out...." Read more

    "...The only weaknesses that I can say is that the pair I got had unequal wire lengths (the right line was twice as long as the left) which I can only..." Read more

    "...have given these a 5 out 5 star rating were it not for the uneven earbud wires and more importantly the thinness of them." Read more

    "Quality of these are great, my only complaint was the length of the cord was a bit short (for my usage at least)...." Read more

    4 Stars
    Have always bought these buds
    First impression was the wires have gotten thinner where they tee off over the years. The bass response seemed, at first, to be slightly less than the ones I bought a couple few years back BUT I am hearing better clarity compared to my old ones. The older ones might have a little more bass response which is good if you’re out biking etc but the older ones had a muddy sound compared to the newer ones.So they’ll do the job.As per usual though along with the thinner wire the pouch seems thinner as well. I tossed it and will use my old one.

    5.0 out of 5 stars fette bässe, super klang, super preis/leistung: perfekt!
    Reviewed in Germany on February 8, 2024
    p.s.: nach einigen tagen intensiven nutzens bin ich sehr begeistert, diese kopfhörer sind wie für mich gemacht und es zeigt mal wieder, dass man in dieser preisklasse sehr gut klingende headphones bekommt, die manch teures exemplar alt aussehen lässt.

    mein geliebter sony inear kopfhörer gab nach ca. 10 jahren den geist auf, es gibt ihn leider nicht mehr...r.i.p.

    ich habe als ersatz teure teufel inears und diesen sennheiser geordert,die 110 euro preisunterschied sind ausser bei der verarbeitung kaum zu spüren!
    überhaupt: ich hatte schon viele inears ausprobiert, die preise sind hier kein klarer indikator für die klangqualität, um die 30 euro gibt es sehr gutklingende modelle.

    mit den richtigen pads gibt es hier einen mächtigen bass auf die ohren, perfekt für drum&bass etc., richtig sitzenden stöpsel sind bei inears absolut essentiell, speziell für die bässe, ich habe eine große sammlung von alten inears und probiere immer aus.

    diese inears sind klein und leicht, sehr bequem.
    tatsächlich sind es die am angenehmsten und best sitzenden inears, die ich kenne, kein langsames rausrutschen etc. wie bei manch anderen, man spürt sie kaum.
    klasse!
    sie sind auf wunsch sehr laut, der klang ist für den preis wirklich erstaunlich, kommt den sony sehr nahe.
    bässe, mitten und höhen sind ausgeglichen, ich habe bassbetonte eq einstellungen und fest sitzende aufsätze, der bass geht tief runter und ist fett, dass es eine freude ist!

    die kabel sind hier sehr dünn und wirken nicht sehr robust, dafür macht der abgewinkelte stecker einen stabilen eindruck, mal schauen, wie lange das durchhält, hier hat der teufel klare vorteile.

    die teufel sind robuster verarbeitet, der klang bei klassik und pop super, aber der bass ist nicht so mächtig...geschmackssache.

    der klang dieser kopfhörer ist genau mein ding!
    für basslastige musik gefallen sie mir mehr als die teuren teufel kopfhörer, die dafür bei klassik etc. die nase etwas vorne haben.

    diese inears kann ich weiterempfehlen, bei dem preis wird es kaum bessere geben!
    ich habe sie gleich nochmal für meine frau geordert, die sie auch super findet.

    sie kommen meinen alten sony sehr nahe, ein würdiger ersatz.

    danke für das lesen und ihre geschätzte aufmerksamkeit!
