    mostly good

    • Written by from Boston

    have had these for 4 months now, ran over 500 miles with them...great sound (i run to edm music, so the bass is great...not sure about music with more highs), it's lightweight, and a fantastic fit.

    however, sweat did get into the mic after a while and everything in that remote piece stopped working, but the sound still comes out just fine.

    Delivers great sound, an excellent fit

    These are my 2nd pair after losing the first.
    Delivers great sound, an excellent fit. Just wished the controls were placed a little lower down the cord as it tends to dangle a little. This can be adjusted using the clips that's provided though. I have had several other brands but my Sennheisers always give the best sound. I use them on my long bike rides and are great.

    I have been searching for an active pair of head phones that are light weight, has lots of base, functional and easy to use. They don't fall off easy to adjust and what else can I say. I am ordering another pair for my honey and myself! Great training accessory. I love my Bose over the ear but this is an awesome alternative for in-ear use.

    Great sound and stays in my ears

    • Written by from London

    I bought these headphones for use at the gym.
    I've tried ones that hook over your ears or earbud ones and when I get a bit sweaty, they just slip out.
    After much research and advice, I decided to opt for these. I cannot fault the sound quality or the fact they actually stay in place when I'm on the treadmill but I must have really odd ears. My right ear was absolutely fine yet after 2 hours in the gym, I could barely touch my left ear, I was so painful and bruised.
    Sadly I'm going to have to return these......gutted as I though I'd found the perfect headphones :-(

    My attempt at a comprehensive review

    • Written by from San Carlos

    I've used these for trail and road running approximately 100 miles now.

    Overall: Great bass, fair to poor highs, great fit, but has a few functional issues.

    Even though the highs are diminished, the bass and overall sound is still better than any headphones of this type I've ever heard. The fit is excellent. It is lightly spring loaded to hold each earbud in your ears. It never slips and is never uncomfortable for me for over 90 minutes at a time. Car traffic can still be heard pretty well.

    The mic and controls are well-placed, but hard to distinguish the buttons while running. I've taken maybe 4 phone calls while running, and everyone has complained about wind noise and basically unusable sound quality. The cable is on the left side, which makes it a poor choice for a hands-free set while driving for me. The behind-the-head frame probably makes these a poor choice for use on an airplane, but I haven't tested that. I have rinsed them with water several times with no change in performance.

    Two biggest complaints: Excessive wind noise while running or in any light breeze, and foam pads that constantly fall off. The wind noise is usually tolerable, but often not. The foam ear pads are a must if you sweat at all. Without them, the rubber earbuds become like toilet plungers on your eardrums. Not good. The foam pads mitigate that problem, but they are far too delicate and easily fall off when taking the headphones off. I have dropped the little foam pads on the trail several times, but miraculously found them again. Sennheiser needs to fix that and they need to give you at least a half dozen spare pairs.

    I do like these, but for the price, they should not have the problems I noted.

    i always go for small ear-buds-on-a-wire... fit my irregular head well and stay put when i am running. i've been through many generations of Sony clip-ear or back-head ear-buds. they were good, but disposable. i jumped up to the Sennheiser's on a money-lark...

    these things are expensive, but well-worth it. incredible bass and dynamic range. i'll never go back to lesser ear-plugs.

    I tried a lot of headphones in different designs, finally I find this one. Sound quality excellent as I only use it listen mp3 during travel. One thing disappoint is the controller button still has room to improve.
