First the sound: it is excellent, the bass is powerful without eclipsing the highs and middles. Sound quality to be found in some helmets, more expensive and less discreet, and some high-end headphones. The immersion is total, whether in classical, reggae, from metal or electro (hardcore included). Really excellent. Gold-plated plug course. Remember to properly drive the nozzles and tips to choose the right according to your ears.
Then comfort: These in-ear headphones are quite comfortable even after prolonged use (even with one ear on the pillow), we do not feel pain or inconvenience. Beware though if you fall asleep with the headphones are really long, quite suddenly they exceed the ear and leave at the slightest touch from behind. But hey, you have to find a few flaws ... It's still not very disturbing.
The headset is supplied with three pairs of tips (S, M and L, M being the default on the helmet) standard very easy to change (except of course if it's your first time). But there is also a small black plastic box (see 4th picture) approximately 75x55x30 mm. Small, but design is useful. And finally, a little piece of plastic which I know the name used to wrap around the cable and attach it to reduce the cable length as needed (rather than the hard stuff it in a pocket and to risk damaging it. I had never seen that in the pack a helmet at this price, it's really great! If I ais opportunity I'll post you a picture of the full package. The entire pack fits in the small box, and luckily because there is not the original packaging (see second image). But it is voluntary, therefore, the package enters the slot mailbox. Practice.
Another argument of these headphones: their strength: and although it is at the rendezvous, rigid cable 1.20m, I love the texture (it does not adhere as some, and that's good). In addition, this cable is very easy to unravel. What is the relationship with the strength? The nodes are the first responsible for the bending of the cables and therefore to death ... All my old headphones ... And believe me I am a test panel to myself, the average life being my headphones about 1 and a half months ... Anyway.
Good is to conclude, excellent sound, comfortable headphones supplied with some quality accessories, strength (no-doubt) foolproof. For a ridiculous price ... Buy them absolutely. Most handymen will even add a spring to provide this helmet the ultimate strength. Pleased to see that the quality is standardized gradually!
