Sennheiser On-Ear 900MHz Wireless RF Headphones

UPDATED/Embellished on 11/11/2017: Ten Stars! I always read reviews here prior to moving ahead. I read many of the one star reviews on this product, however, another thing I consider is the number of 3 or less star reviews compared to 4 and 5. So I took a chance and must say these headphones are working very well for me. The range is awesome with hardly any interference, the battery lasts long enough and the cycle of pleasing is sufficient. Seems most of the negativity is based on the unit being difficult to the right frequency. The tuning wheel must be turned very slowly, as it's covering many frequency bands with every tiny movement. Not difficult at all if the tuning is done slowly. This is FINE tuning. As for the range? It's unbelievably good. So long as the base is not in a metal room, in your average house with drywall you can easily walk to every part of the home, garage and yard without losing the signal. Of course if there is a lot of metal, chain link or if the base is in a bomb shelter, the range will be less. There is also an additional bank of frequencies available simply by flipping the switch on the bottom. More than enough tuning capacity to meet most every, if not all applications. Negative reviews regarding hiss are either caused by poor transmitter location and/or improper frequency tuning. Also, it's important to know if there is no signal going into the system, there is nothing to transmit but static, and that's exactly what you'll get! When the audio signal is interrupted (pausing or stopping a DVD, TV powering off, etc.) The headphone system will "time out" after no input signal is sensed after 2-3 minutes and you will indeed get bombarded with white noise / static. THIS IS NOT A DEFECT. If there's no "sound" going into the system, there's just dead air being transmitted. Dead air sounds like this: "Swishhhhhhhhhh!" Another complaint had to do with extreme difficulty hanging the headphones on the charger/transmitter/base. If the base is level there is no problem. I did however experience what one reviewer documented, which is having to tinker a long time hanging the headphones on the base until the charging light would stay on. Over the years the metal strips on the base (which charge the headphones) can and will collect dirt or tarnish. I used a jewelry cleaning rag to shine them up and once again, just plopping the phones on the charger is all it takes. Someone mentioned the volume and tuning wheels are too close together, but they're not too close so long as you're careful. If you're wearing gloves or have 5 thumbs on one hand, yes, you will have trouble turning the tuning and volume separately. Only thing for me is the light weight of the headphones. Overall this is a merry thing, except when I need to tie my shoes or swing my head around wildly (which I often do when reviewing here). All in all the price, comfort, function and sound quality are awesome, and that's a word I use way too much, just like most you all. Enjoy these, you will not regret a day in at all. As of the time of this embellished input of informationary review for your reading digestion, I've had my set over six years now. I have moved 3 times and have obtained phenomenal signal in all 3 locations. I've sat in my car outside, walked around the house, every room, upstairs, downstairs, etc. (basements might be a problem) out in the yard, etc. As I mentioned earlier, the transmitter must be in a suitable location, away from AC lines, metal, and formulated ionic sentries, etc. The tone is excellent! Better than the TV speakers. The original rechargeable batteries lasted almost 3-years before they quit. Easy to replace. You can even replace the rechargeable batteries with regular batteries, just DO NOT hang it on the charging station. Also! Additional headsets can be purchased and will work off one transmitter, however, since additional headphone sets cost more than the entire kit (with charger/transmitter), I'd recommend just getting two kits just because. Best if plugged into the external speaker output on your TV, then the TV can be turned down as these have their own volume. Multiple headsets are a great if you rent, have kids, rent from kids or have other reasons to keep your TV volume lower than any particular need therewith. Only thing with multiple headsets would be the recharging with only one base. Guess what? You can put [2] regular AAA batteries in the additional set(s) and forgo the recharging in those set(s). Considering the excellent tone and range, the excellent reputation Sennheiser enjoys, all this $300 level quality and performance for less than $70? Geez! Such a deal should be kept secret, so, please don't tell anyone! 10/26/2020: I had updated and reduced stars, thinking my second unit has also stopped transmitting after a feew years. Well, I found out this was due to the unit needing an internal reset (after a power surge). Unplugged from AC and Audio, removed batteries from headset, waited 15 minutes and POW! Both units work! So, 5 starts remain.
