There is a huge proliferation of headphones so you will be forgiven to think they are all the same thereby restricting yourself to using price as the only panacea. Trust me, you will be wrong. The Adidas PX 685i Sennheiser Sports are, without doubt a premium product that delivers. I have been a fan of in-ear headphones for donkeys years but have to admit the traditional dangling cables mean, if you are a gym or jogging type (like me!), they can be very frustrating. The PX 685i 'phones have solved that particular problem brilliantly. They stay in and stay on thanks to the cute head band. That retro touch may not be everyone's cup of tea, and I must confess, the feature made me pause a while, but for what they are meant for (clue in the name) the design actually works.
When it comes to what really matters i.e. sound quality, this, I have to say, is top notch. The bass is just right and the treble is just perfect. Add to that the cute 'smart remote' which allows you to change tracks if you so wish without taking your phone/player out of your pocket. The microphone also allows for taking calls without breaking your stride. The versatility does not end there as these are compatible with the iPhone, notoriously a closed garden and you can still execute your voice commands using the headphone's mike.
These compare very well with my old (3 years and counting) trusty pair of Sony MDR-EX300 which has served me very well for all this time except when I hit the gym. The sound quality on the Sony is great but these are actually better and of-course their ability to stay on even with a vigorous treadmill stint is a distinct bonus.
I am not big on running outside in the elements but was recently caught out in the rain and decided I was not going to let go of my music so subjected them to the downpour for over half an hour. They seemed to have coped OK and I haven't noticed any change in sound quality.
All in all, a very decent buy.
The cons? Well, these headphones are kinda of pricey and I suspect with this being a combined Sennheiser Adidas venture; that is not a surprise. Also, the head-band style may not be for everybody. I was also rather surprised to find no real choice of colours for the actual head band, the most visible and the 'statement' part of the device (I could have any colour as long as it was white or black). I do think the designers missed a trick here as they could have been bolder.
In summary (repeated below of course) these headphones have a high quality sound production, are versatile, appear durable (only time and use will tell) and have a nice understated retro style. On the minus side they are decidedly more expensive than most of us are comfortable shelling out (this will inevitably change with the passage of time - if you are the patient kind) and the styling is in the Marmite category.
