March 17, 201411 yr I bought a wireless headset OKER WH 9000. I thought of buying a few sets for friends in north america but wondered if perhaps they might not work there. Here are the specs: Modulation system: VHF/RF transmission frequency: 86+- 0.5 MHz receive band 84-88 mhz 84-108 mhz headphone frequency response: 30-20,000hz
March 17, 201411 yr Why wouldn't they work there? If you're thinking about legality, the operating frequency is at the beginning of the US FM Radio Band. Lots of devices transmit in this range. US FM-Radio Band allocation 87.8–108 MHz

Lots of devices transmit in this range. US FM-Radio Band allocation 87.8–108 MHz thanks. I just don't know anything about frequencies and I was not sure if for example the frequencies on which the headphones operated would not be compatible with systems in north america (analogy= buying dvds in thailand for use in north america without knowing the difference between pal and ntsc.)

I wasn't planning on using the microphone- just the headphones. I'm not sure I understand this information re wireless microphone designations (?? :>)
March 17, 201411 yr The headphones you referenced in your OP (OKER WH 9000) is a two-piece unit: the external box has connectors for TRANSMITTING Stereo input to the Headset on 86.0 MHz. Normally these types of devices have to pass CE inspection before they can be allowed into and legally used in Canada. If only the Headset (receiver) was used then there probably won't be a problem.
March 18, 201411 yr I've had several pairs of OKER headphones (standard wired, purchased at Pantip Plaza)) and while they were very inexpensive, they fell apart rather quickly. The ear pads constantly fell off and the extremely thin faux-leather material quickly peeled off. Don't expect to get more than a years normal use out of them. On the plus side, their sound quality was surprisingly good considering the price and the microphone pick-up on 2 way headphones delivered very clear speech when used for VOIP calls.
March 19, 201411 yr Can anyone tell me what sort of headphones to buy for watching/listening to the TV? I don't want Super Duper High end ones. Just a set to do the job.
