Just a quick note, "noise cancellation" usually refers to active circuits built into the headphones/earphones/IEMs. These usually work best on background or droning noises, but won't be of much help if, for example, the baby in the seat behind you starts crying.

"Noise isolation" on the other hand is plain old blocking out sounds, in the same way that earplugs or earmuffs do.

Pardon for necroing a necroed thread - anybody have anything on Logitech Wireless Headphones, particularly these two: or [url=http://www.amazon.com/Logitech-Wireless-Headset-Stereo-Audio/dp/B0040QMB8O]F540?

Looking for a wireless set primarily for music and the occasional voice chat (built-in mic not necessary though). I'm no audiophile so decent enough sound quality with a reliable connection is mostly what I'm after.

The F540 seems discontinued (hence the lack of a product page) and primarily designed for consoles, but apparently works with PCs.
Are the mentioned ones decent enough for ~$100, is Logitech even viable in the Wireless Headset market (went with them only because of a local promo, they'd still be ~$90 though, seem overpriced around here)?

Or rather, is ~$100 enough for a decent wireless, or is it still not worth it at that lower range? Googling rather gave me a hesitant "no" but maybe someone here has some secret/better info/insight.

I've been using Creative EP630 for more than 5 years, still rocks (I guess? :p)

Mine are Audio-technica model ATH-M20 according to what's printed on the side. All the old pairs of (cheap) earbuds I used to use broke too easily, and some of them made sores inside my ears which was less than pleasant as you might imagine. These are bulkier, sure, but they're comfortable and seem a lot more durable. I'm not enough of an audiophile to really talk about sound quality though. They work for me.

I'll ask the question here, as I am not getting answers from the company or specialized forums.

Do two separate wireless headphone systems in a same house (one for computer, the other for tv) conflict with each others if they are from the same brand ?

More specifically, when they are sennheiser rs 170, a model which, for some reason, doesn't seem to offer chanel selection settings (I've heard that lder models did ?).

More specifically, could one headset be occasionally switched from one emitter's frequency to the other ? Like, using the same headset sometimes on the tv emitter, and sometimes on the pc's emitter ?

Has anyone any experience with juggling with such devices, or some understanding of how modern sennheiser headphones work ? Or, failing this, an idea of where to check ?

I own two pairs of headphones, my favorite being a pair of Sony Stereo MDR-ZX100 headphones that I bought at Best Buy for $20 a few years ago, they sound great, nice full sound, are pretty durable and they're comfortable to wear. I would buy them again.

The other pair of headphones is a pair of Sennheiser HD 201 headphones, they are really quiet and tinny, and have a odd shape that can get uncomfortable rather quickly. I paid $40 for the Sennheiser HD 201 headphones. I would not buy them again.

I don't think they will interfere with each other because the transmitter has to be paired with the headset.
cant say that I'm sure, but as long as you don't activate the multiple headset connect mode, it should be fine.

I own a set of the RS-140, but not another set. So, I have no experience to share with you. But they are still running after 7 years...The earcups are starting to get a little aged, but otherwise no worse for the wear.

The RS170's (as well as 160's and 180's, I've got the 160's) use Kleer, a proprietary digital transmission tech over the 2.4GHz band (the previous models, like the 140's use 900MHz). The signal can drop out, but shouldn't pick up any interferences like regular RF did.

As alien mentioned there shouldn't be any conflicts between headsets since they get paired to the transmitter. Not sure about Your set-up, but If You have two emitters, one plugged into the PC and another into the TV, You'd just need to re-pair the headset every time (each transmitter can be synced with up to four headsets at the same time so there shouldn't be any issues).

For some more info, I found this thread on the Head-Fi forums useful when I'd been looking into the 160/170/180 line (a Sennheiser rep seems to be answering people quite regularly there).

Ok, thank you a lot.

When you say "can drop out" do you mean that yo occasionally hear little blanks, little interruptions ?

Yep, exactly, but that's only when out of range, or behind a thick wall that kills the signal for example. For regular use within the same room as the transmitter I found it pretty much flawless.

With the 160 plugged into my PC, I can walk around the apartment freely and it only "drops out" on the balcony, when I'm standing at a spot that's behind a thicker wall. The 170 has a much better transmitter supposedly (theoretically with a max range of 80m in line-of-sight, the 160 "only" 20m) so I don't think You'll have any connectivity issues within reasonable range.

Have you experienced micro-dropouts near the emitter, in the instant where a movie gets silent ? I mean, when the movie is silent with background white noise, but the headphone simply shuts it to absolute silence for a second ?

I don't think so, but I'll try that out later today. I do recall reading about something similar, I think the advice was to set the headphone volume as low as possible, and as high as needed on the source, but I might be mixing stuff up here. I'll see if I can dig out a link for that.

Edit: this Amazon user review cites the same advice:
Transmission from the base station to the headset seems to require the input signal amplitude to pass a certain, small threshold. As a consequence, transmission cuts in and out during an extremely quiet part of music. It is therefore a good idea to follow the suggestion in the manual to turn up the volume of the input device as much as possible (but avoiding distortions) and to regulate the volume directly on the headphones.

I used mine for years as well. Someone said they were on par with the famous Sennheiser CX (forget the model number)....they were superb the creatives. Shame mine broke ($30 worth). Bought a few cheap ep630 clones which apparently came from same factories as the originals.. but they didnt last very long at all. Tried replacing the original EP630';s with Altec (cheap but marginally better than the cheap creative copies), and Brainwavz M5 - these seem to be ok but still... (kinda giving the IEM's a rest... sore ears and all). May end up coughing up more money for original EP 630's before they EOL (if ever)


Whats peoples opinions on bluetooth headphones?. Got a cheap overear (wrap around back of head types) which seem to work well but only lasts around 10 hours (good for cheapies ehhe) and range is pretty poor around 6-7m. Good for home and also been using them as walk abouts outside (hooked to my mobile) as well...
