Before you read any further, I'll point out that these "sound isolating" earphones retail on average at nearly three hundred pounds a pair (that's not a miss print). Therefore for the average consumer (or at least those of us who are not football players or other famous figures) the idea of spending...

The Shure 535 noise isolating earphones are the best on the market for you audiophiles out there. They have Triple High Definition Micro drivers which are composed of 2 woofers and a dedicated tweeter. This gives the Shure 535's the best all round sound.

Sound Quality; Design Quality

Cost

Less than six months after purchasing the left earbud stopped working ( a quick search seems to show this is a common problem), as of yet I have had no joy getting shire to replace them. Avoid.

If you can afford the price, just buy it. I will not go to deep explanation about cables, frequencies, fit in, e.t.c I love listen music ALL the kinds and 535s can cover ALL the kinds, perfect.

Everything

Hard to find something bad

I have owned these (previously the SE530) for some time and I would never look back. The feel weightless, wrap around your ear, fit snuggly in ear, and deliver the most beautiful sound I have ever heard from an In Ear device.

Sound quality is awesome IF YOU CAN GET A GOOD FIT. I struggle to get a good fit in one ear. Can't get a good fit at all with the supplied foam tips. I have also tried various Comply foam tips, but again no joy.

I have had several pairs of Shures over the years: always top quality sound but I have had some issues with reliability. They need to be treated with care.

Shure Incorporated had its humble start in Chicago, founded by Sidney N. Shure back in 1925.  The company in those days was simply a radio parts company.  Fast forward 88 years and the company has grown considerably in size and diversity; now a manufacturer of both consumer and professional...

The cables themselves are the first things that shout "high quality". Shure has gone with a new Kevlar-reinforced material that's far more resilient than standard plastic, and they've added gold-plated connectors right on the monitors themselves.

Perfect sound quality; replaceable cables

Takes some time to get used to the fit

At last, after many years of wasting so much money on inferior but big name in-ear earphones I have found earphone nirvana.
