Philips SHN2500 Active Noise Canceling Headphones Review: The Philips SHN2500 can reduce external noise but not totally. It is good especially when traveling and need something to listen to that can also reduce surrounding noise. This pair of earbud headphone also comes at a good price. The cord of Philips SHN2500 earphones are quite long at 6 inches but here comes the problem according to one customer,
“…in the middle, there is the bulky Noise Canceling switch that holds the AA battery. Not a problem when you are sitting (eg. on and airplane, or at work) because you can just set it down. But for example, when you are walking, it hardly reaches your pants pocket, so you can’t stand up straight, or it will pull the buds out of your ears. Leaving it hanging will do the same thing. In fact, this has been such an annoyance to me, that I never use these anytime I’m being active. And it’s a shame, because they do a good job of cancelling lawnmower noise.”
Bottom line: The Philips SHN2500 Active Noise Canceling Headphones is a nice pair of earphones for its price but you have to get used to the bulky noise canceling switch. Better yet, just go for isolation earphones like the Maximo iM-490 iMetal Isolation Earphones.
