Summary: No hissing or humming and audio clarity. on lower volumes you dont have much bass impact but its no worse than a pair of earbuds. Its defiantly worth going with the brand name. Cups are just as slim in real life as the picture suggests.
Summary: I have found Phillips headphones and earphones to be of good quality and a better sound than some i've paid 3 or 4 times more for. My only gripe is with the instructions, theres no mention of holding the button for 7 seconds to pair until you look up the full manual online!
Summary: Connects to my Iphone and Ipad, all controls work fine and the battery life is very good longest I have used them is 5 hours without recharging and I am sure that they would last a lot longer. Bonus feature that I found out by accident is that holding down the volume up button on the headphone fast forwards the track, very useful . Range works in all rooms in my semi detached with leaving the ipad in the lounge.
Summary: Can't compare with other Bluetooth headphones as these are the first I've ever bought, but they were easy to set up, my iPhone and iPad pick them up straightway when I want to use them, the sound is great, they're comfy to wear, hold their charge for ages - would definitely recommend.
Summary: It does look flimsey, but is not, yes you could scratch the matt paint off easily, speakers do not turn as in 5000 to allow to be folded up flat. But these fixes are in the next models up 5000 and 9000 series, so this 4000 series model is cheaper. It does what it says. Got mine for £24 so a bargin as the rrp is £45 an now the current price is up to £37 on here.
