Pros: Pretty impressive sound
Cons: build quality
Spend some time googling for decent budget earbuds and sooner or later you'll stumle upon Philips. There's some raving reviews out there for their SHE3580 which went out of production in 2012. According to Philips product support this is the same device with just the colours changed a bit.
Where to buy?
Over here in north-west Europe they're easy to find with most big name stores as well as the bigger online retailers stocking them. Expect to pay between 8 and 10 euros for the white or black. Price and availability of the fancier colours varies.
What's in the package?
The little plastic tube contains a piece of cardboard that proudly proclaims "dynamic bass", 3 sets of tips and a cute little set of earbuds. Everything is easily separated for recycling purposes.
Getting a good seal with these was tricky but I do have a weird ear canal, it's relatively big, oval and changes direction really easily. The tips are of soft silicon as you'd except and because their opening is round and the tip of the phones is oval they are tricky to change but stay in place well. The cable is smooth enough not to supper from microphonics easily. The earphones are really light. Build quality is lacking, these do need some care or they will break.
How do they sound
Initially... terrible! Really muffled. Apparently these are really in need of burning in, something which I don't believe in normally. But leaving them on overnight did improve matters tremendously.
There's bass, if you get a good seal, but it's not oppressive or distorted like the Sennheiser CX300 or the beatz. There's enough there to give your music some body and it does go pretty low. it can get a touch muddy if you have multiple instruments there.
Mids are nice and come across fairly neutral
Highs can go really high but there is the occasional bit of sibilance on female focus.
I am amazed at what Philips can do for 9 euros. These sound better than my old sennheiser pmx 60 and come close to the PX100. They don't necessarily beat the sennheiser CX 300-II since there is a market for audio which hugely inflated bass but to me they do.
Rock: Yeah, it works for that. Listened to some live recordings. Nice soundstage, good instrument seperation.
Classical: Acceptable but struggling a bit sometimes. On chamber music they did ok, bigger symphonies and some things muddle a bit like the string section.
Jazz: Totally fine for that
You have to consider these verdicts in perspective. Do these outperform a set of decent full sized headphones? No of course not! But for casual listening without annoyance these will do just fine for many people. Their relatively neutral sound profile means you can listen for extended periods of time without getting tired. They are suitable for travel or discrete office use and at a price point where damage or loss isn't a real issue.
