I own a pair of Sennheiser 170's and they are really excellent headphones but @ over $200 I didn't want to spend as much since major use of these 120's was my bedroom TV. PS, if you're buying a tv these days, be careful to check the back before buying. Most decent size LCDs/plasma's don't have headphone jacks, many do not have RCA audio outputs, and some cheap models don't even have optical outputs. I'm not sure how optical to RCA converters worked, so, I wanted one with RCA audio out in addition to optical, and second choice would be headphone jack. In my humble opinion, RCA-output is the best because there is constant output level and you then control the TV speakers with the mute button on your remote. If you are limited to a headphone jack, the speakers usually are cut out when the phones are plugged in making it necessary to be plugging and unplugging whenever you use the phones and then want to go back to the speakers. Back to the 120's. First of all - sound quality is excellent, tho I don't use them primarily for music, I'd have no hesitation to do so. Unlike the 170 and 180's they don't have features like base boost nor do they have the surround sound simulation that the 170/180's have. PS: this feature on the 170's is really cool and I love using them on my family room tv for action movies. But, back to the 120's: even without these features, the sound is great. Next, reception: unbelievable. I've been all over my house to test them and they work great, even on different floors. Next: comfort. I actually really like the "on the ear" fit for my purposes. Soft pads, no irritation, but haven't yet worn for hours. I can say that, since I have both, there is one advantage of these compared with "over the ear" fit that is a feature of the 170's. With over the ear, if your head is resting on a cushion/pillow such that the cushion/pillow pushes on the earpiece, it causes the earpiece to put pressure on the back of your ear and actually can cause irritation. It's my one complaint (albeit minor) about my 170's. The one problem wiht the "on ear" fit of the 120's is that it is not "secure" - i.e, because they fit lightly and comfortably, if you want to wear them while you're say doing a project that requires bending over, they'll tend to slip off your head/ears. If you're sitting, at your computer, lying down for a nap, no problem. But if you''re going to be active with them - like working in the garage or cleaning the house while wearing them, might consider the more secure fit of over the ear. Since they're not over the ear, they're not as noise isolating, but that can be an advantage if you want to know what's going on around you - like hearing your wife calling you or the doorbell, etc. Finally, as for some of the criticisms of others that I've seen posted on these reviews, here's my take:
1. Hiss: non existent. none. I'm using these with RCA outputs on my tv that have constant output and in this mode 0 hiss at any volume even with total silence on the source. If you're using headphone jack output, probably should have the component volume up enough (normal listening level) so you don't have to crank the phones - but I've pushed the volume on these during silence on screen without any hiss!!
2. Unable to charge with earpieces extended. Huh? Maybe they've changed the design of base unit, but this is simply NOT true. I've extended them all the way and set on the base to charge. No problemo.
3. Volume control on same side as tuning wheel. Please.
4. Auto on/off. So far no problem while watching TV. I suppose if you're pausing dvd's frequently, this could be a minor annoyance, but if you're wearing wireless headphones the need to pause should be minimal, since you can keep listening while you grab a beer in the kitchen or take care of business in the bathroom! Here's the bottom line on this: I TURNED THE TV OFF AND CLOCKED THE TIME-TO-AUTO-SHUTOFF: 3 minutes exactly. So.. how can this be a problem listening to music: suggest if this a problem you are using a headphone jack and the component volume is set incredibly low, turn it up a bit! Oh, yeah, when the base is off, then turn the tv on, the time between tv volume "on" and base unit auto on is virtually instantaneous. Again if, not getting this performance, suspect it is headphone jack and component volume problem.
Overall: this is a great set of wireless headphones at a reasonable price (less than $100 on amazon) and the problems noted by others have either been engineered out of the product over the years (some of the negative reviews are years old), or the folks with problems haven't set them up correctly (using headphone jack with component volume turned too low). For best results, try the rca audio outputs and if you're going to buy a new tv, look for and get a tv that has this feature!

Customer Review: Garbage headphones!! DO NOT PURCHASE!!!!!

Manufacturer design flaws
I’ve purchased these headphones Dec 2 2014 and have used them ever since. I’m hearing impaired and now can watch tv without disturbing the rest of my family. As for quality I’m not an audio tech type person, but I must say the first time I used the headphones I was and still am amazed of the sound quality. Some reviewers complained about the loose fit. I also found this to be an issue. Within the first 6 months the headphones would slide off my head if I tilted my head forward, especially when I got up from my recliner to retrieve an item from across the room. When the headphone falls and drop to the floor (hardwood floors) the earpiece would detach and fall away. One time the plastic retainer clip that secures the earpiece to the headphones snapped and could not be repaired. After numerous attempts to contact support I finally spoke to a person only to learn that to resolve the issue I must purchase a replacement pair (not one, but a pair) earpieces. Right after that incident I attached cloth weaved strap from right earpiece to left earpiece with slight slack. (See attached photo). Now I can completely tilt my head forward and even shack my head and the phones stay in place. I minor fix to a flaw in manufacturer’s design. Over the years of use I’ve found other flaws which were not a big issue. However this past week I’ve become confined to my recliner due to a right rotator cuff surgery. The flaws are as some other users have stated in their reviews, is the volume control wheel and the tuner wheel are located too close together and can become confusing. And since my right arm is incapacitated I must use my left hand to adjust the controls further confusing the control wheels. The other flaw I discovered is the control wheels are on the back side of the right earpiece. When I am reclined in my chair the headphones rub against the chair headrest causing the control wheels to rotate and throwing off the volume and the tuner frequency. Very awkward to keep headphones in place and readjust the controls back to desired setting with left hand. As others stated in their reviews regarding the inconsistency in the charging contacts, I don’t find an issue with the charging contacts, as I have the charging station (see attached photo) that the headphones hang on the charger. Every so often I clean the hanger and the contacts on the headphones. I find if I place the headphones on the charger with the “E’s from the brand name on the top lined up with the hanger it makes a good contact. P.S. Another issue happened approximately 6 months ago. After 4 1/2 years of use the volume control wheel would cut in and out. Just like an old radio volume control. I dabble in electronics. This is usually caused by a dirty control. Just needed some contact cleaner sprayed on the inside of the volume control. I wouldn’t recommend this procedure for anyone that is unfamiliar with electronics and especially if your product is still under warranty. In closing, sound quality, stereo effects, setup and price-Thumbs up. As I mentioned in my review, I overcame some of my issues with a little ingenuity (with exception of the issue of the location of the control wheels) I have a product that I can live with. Not all products can be 100% flawless. For this price, not bad. BTW: this very week I discovered the rechargeable supplied batteries just gave out. Great 4 1/2 year run.NOTE: To Sennheiser, Next model place the controls on the front of the earpiece. Also add a back strap or design a more secure headphone.
