Summary: Having had a set of Sennheiser MX300 II earphones break down after 5 months of active (gym/sports) use the common "dead left ear" came, so I tried these buying into the "booming bass". This could not be further from the truth! Earphone fit feels similar to most other wrap-around sports earphones with admittedly slightly less bud movement during running, though this does not counter the overall poor fit regardless of earpiece used.
Summary: As someone who has tried almost every brand of sports headphone I can tell you that none of them are perfect and even these won't last forever if you train a lot. However I think these Phillips are the best you can get under £25. The splash/sweat proofing works well, the sound quality is very good and the lead is sturdy enough to withstand heavy use.
Summary: These are my second pair of these headphones and I still absolutely love them. Great colour, well made, they don't move while you have them on and for me as a avid runner this is a must! Buy them!
Summary: I have a set of Klipsch earphones which are great for day-to-day usage but not particularly practical for the gym or running. I was a bit worried about these as I had bought some cheaper earphones on Amazon and they turned out to be terrible and pretty much unusable (cheap wire, terrible sound quality etc). Not so with these Philips headphones! The sound quality was good, which was a pleasant surprise.
Summary: I use these for running and walking in all weather. Have even used them in the bath! I'm not a fussy user so I cant comment on sound quality or bass as other peoples reviews, but I can say they stay on, function well, are water proof and comfortable. I listen to music and audio books with them and find the sound quality to be just fine. I've had my current pair for many months now and they still look good as new.
