I have been a user of TV Ears for many years.  As a quality hearing device they are wonderful.  As for quality, there is a lot of room for improvement.  The new 5.0 digital is extremely uncomfortable and actually hurts your ears.  I was told this was a new version and the arms were made not to break.  Wrong; I can't tell you how careful I am with the ear pieces, because I have had upwards of 5 or 6 break.

I purchased an entire new set back in December 2014 and tow have now broken.  Upon calling customer service I was told a new set, just like I had would be $53.00.

It is time to find a new manufacturer with a better quality product.  Enough is enough.

At first I did not like them at all due to poor seal in my ears (and poor seal = poor sound) until I replaced the tips with Shure Olives. The fit is much better now, still not perfect though. At least they are not falling out anymore and do not require frequent adjustments.
The summary:
Sound quality - 4 stars, on par with what you can get out of Apple devices or better (with supplied tips my rating was 2 stars, so Shure tip caused a significant jump)
Controls - 5 stars. I love it for the fact that this 3-button control is reliable and gives me full control of my device, not just 'stop and go' like most other earphones equipped with 1-button control.
Comfort and fit - Shure Olives improved my rating from 1 star to 3.5 stars, but that may vary from user to user. Still, the bulky back ends don't sit properly inside of my ears and cables are connected at weird angle. Remote control placed very high, making over-the-ear cable placement virtually impossible.
Build quality - 4 stars. No complains other than above mentioned design flaw. Cables do not get tangled excessively, there is some noise caused by cable rubbing (not too bad).
Durability - no verdict yet, I've used them occasionally for 6 months and they are still as good as new. But I'm one of those people who never break or lose anything, therefore I may not be the best case study.
Looks - no verdict because I don't care and is subjective anyway. That's what product's picture is for.

Not the best I ever had (and I had / have quite a few), but clearly above average.
PS They cannot be inserted deep into my ears like Etymotics and for that reason the outside noise isolation is not nearly as good

Update: after a few months of gentle use the cord started developing permanent kinks above the jack. Now it's been about 18 months since I bought these earphones and it seems like they are near the end of their lifetime (it's been a good life though). The cord will break any day now, I'm sure. Still keeping my rating unchanged at 4 stars for overall value.

I purchased these from originally from a retail store. Not Amazon. So take that for what it is worth. I was looking for a new pair and saw these on Amazon but chose something else instead.
Pros
Sound: The sound is fantastic for what I use them for. The highs are crisp and the lows sound like bass instead of a muffled tunnel. I plugged them into my iphone 5s and I put the phone into my pocket and kept the volume control buttons near my neck where I could reach it. I would ride my motorcycle from work to home each day. I could answer phone calls with just a push of the center button. The calls I received had no idea that I was driving at 60 miles an hour on a motorcycle. I could hear them perfectly. The music was great as well.
FIT: They come with a couple of different ear pieces so that they can fit your ear correctly. In addition you can send in to the manufacturer and have them send you a custom set just for you. You have to move the orange rubber ear pieces around so that they fit to your ear canal but once you find the correct angle. they are great and comfortable.
Ambient Noise: It has the perfect amount of ambient noise so that I can listen to music and still hear if people are speaking to me. Perfect for riding a motorcycle and listening to music because I can still hear traffic noises which helps me remain safe. I wore these both with and without a helmet. (Don't Judge on the Helmet thing.)
CONS:
Quality: One side of the first pair I purchased quit working after a few months. The replacement also quit working after a couple of months. I was driving along on my motorcycle and looked over my shoulder and when I looked back the one side had quit working. I had kept slack in the cord because I didn't like it pulling against my neck when I had to rotate my head. So, the movement when I looked behind me was minimal.

Customer Support: I called the manufacturer and asked for an advance replacement. They refused. I offered to give my credit card as collateral in case I didn't sent back the defective pair. They refused. I finally let them know that I could still use them with one side working and that I wanted to do that so that I wasn't going without and that if I had to send in the current pair then I would forgo being without anything by purchasing something else for the interim and that by allowing me to do this Yurbuds was risking that the item I was going to purchase to get me by, would be better than what they had and thereby I would change loyalties. I of course spent 8 minutes explaining to the Stubborn customer support person the logic of my pending actions. I explained that this was like buying a toaster. If it breaks it isn't worth the effort to get it replaced I would just buy a new one and the new one may not be Yurbuds. After 8 minutes of my wasted time she finally relented and agreed to send me an advance replacement. Which I received and 2 days later and for which I was thankful for.  However I resented having to spend time convincing the customer support person that it was in Yurbuds best interest to replace them under warranty.
When the second pair also failed after a couple of months I didn't bother calling them back. I just went and purchased a new pair.

I am VERY pleased with the quality of these earbuds.  At first I was not sure that  they were all they were cracked up to be, but after switching from the triple flange to the double flange, I got a better fit for my ear canals and the sound is very impressive!

These sound great, they may be a bit bright for some folks, but I like them.  The only negatives are the ear cups and pads and the overall quality.  I wish the holes were a bit larger or even oblong to accommodate normal ears (my ears do fit, but takes some adjustment to get them in there).  The ear pads are velour which I prefer, however the foam they used seems cheap and almost "crunchy" for lack of a better word to describe them.  I still really like these for the price which is good for a nice sounding set of phones.  Comfort, despite the problems is not bad, I can use them for a long time without problems.

Isolation just OK (I really wish this was better), and quality seems like an only time will tell thing, but they do not inspire much confidence, they feel cheap.  I can live with these problems though, did I mention they sound good?

Good sound, great quality, it's a Sennheiser.  What do you expect?

First of all, let's get the cons out of the way. I only have 1 major con.
Number 1: The eartips provided are mandatory for a sure fit. When you have the right eartip on, the sound is INCREDIBLE. The bass is strong but isn't overpowering as it lets the middle and treble through quite well.

Now that that is out of the way, the pros.
Number 1: As said before, the sound quality is great, especially when paired with a music player that can change the bass, mids and treble like Poweramp. If you don't have that, then it's okay because the earbuds come equipped with their own equalizer settings.
Number 2: I love how long pressing the front button can activate and help you interact with Google Assistant. It is so helpful as I no longer have to go to my phone to tell google to call someone. I can be in another room and still make a phone call with really clear audio. No issues asking the other party or vice versa to speak up or repeat what they said.
Number 3: The longevity, oh my goodness.... At the time of writing this review, I would have had these earbuds since Christmas 2015 and they are STILL GOING STRONG. Of course because of age the bass is disappearing but other than that the battery still holds up well, I still get at least 2 days of standby and quick charging, about 1.5 to 2 hours and they are full.

Overall, I would HIGHLY recommend these as they are really worth the money. Unless your a heavy exerciser or a runner, these do an OUTSTANDING job for the price. I would most certainly purchase again.

They are comfortable for me.  They fit close to my head and make a perfect seal. Although I can hear much reduced conversation, a sudden noise like a clap or bang is practically cancelled.  They are SO much better than my old pair which I (fortunately) lost in my move!  Yes, I would definitely recommend them to a friend or relative.

Absolutely brilliant!, they're clear when I talk to my hubby,  great for radio & audio books &  music too!,  but if you want something to burst your eardrums..  I recommend you buy those overpriced ones that impress your mates

These are fantastic cans that deliver on the promise of full immersion.

Noise Isolation: I prefer closed-back for travel and these do a wonderful job of blocking out noise from your surroundings.

Build: The quality of the construction is also top notch with great materials and finishes and modern yet subtle orange highlights.

Comfort: The memory foam on the ear pads remain cool so wearing these for extended periods is pain/heat free. These are very comfortable. They feel much lighter than they actually are.

Sound: The quality is top notch. Excellent clarity and detail with good bass.

Great product: quality of sound is terrific. There are two issues 1) durability - cord from right ear could get damaged over time because there's no way to ensure it won't get entangled and 2) volume control is missing ...I thought my purchase involved earphones with volume control

It's somewhere between good and great.

I am conservative in my rankings, I feel those who buy stuff have the all-too-human tendancy to "talk things up a bit," since their choices/money are on the line. Therefore I am conservative.

I work in a server room w/ fans humming 24x7.

Upside - Noise cancellation does indeed work, and work well. It kills the noise "for sure" and the modest amplification does indeed help for a clean un-colored sound. All the details come thru and I can still hear my colleagues due to the relatively open design of the 'phones. I listen to classical music mostly, and I hear the subtle details using these 'phones quite well. Accolades on this account.

Less bass and frequency response than my Sony MDR-71's which have excellent acoustical isolation, and therefore great response. BUT the Sony's have downsides too, as they can't be worn for 5+ hours comfortably and if one has to listen to occasional inquiries they tend to be too isolating. I am glad to own both, as each has it's uses.

Senn downside: The fit leaves something to be desired though. I always feel as they will pop off like a cork on champagne. BUT they have yet to do so, even in shaking my head vigorously, therefore I would rate them superior and far more cost effective than the (IMO) overpriced Bose NC 'sets.

Okay first off I received the incorrect ones.  I purchased the earbuds with the charging case however i was sent the ones without a case.  No biggie I can just return it but it was quite inconvenient.  In the end I was too busy to return them so I just gave them away as a gift.

As for quality, this things are great.  At first I had a bit of an issue getting them to fit in my ears but after I figured out that they have things on them to hold them into your ear they work great.  I run miles and miles and never have an issue.  At the gym they stay in my ears.  And the quality is great.  Sometimes wish the battery was a little longer but can't expect too much from a set of wireless earbuds.  Definitely do not regret buying these.

have been very happy with them so far. the sound quality is good, though to be honest, I'm not an audiophile.

This is a luxury item with a corresponding price.  For that reason, I have high expectations and I found material shortcomings.

First, though, I want to mention the positives.  Except as noted below, the build quality is lovely.  There are few items that I own that ooze this degree of class and beauty.  I simply adore it.  The moving components slide smooth, the leather is sumptuous, and the color choice is a home run.

The touch controls are great.  The ability to adjust volume and tracks was simple and liberating.  Nicely done.  I deemed the sound quality to be very good.

Now for the negatives.  I have to say that my expectations of the noise cancelling were not met.  I tested the Bose noise-cancelling headphones, the Quitecomfort 25, and the noise blocking was dramatic.  I expected the same results here but it was just okay.  Maybe the developers wanted to balance the strength of the noise cancelling with sound fidelity, since the dampening introduces a slight hiss, and the Bose headset has crummy sound.  Worse, however, at least with my particular headset, I experienced some odd sound aberrations that I think is a defect.  Just listening to the silence, I would sometimes hear a rumbling sound like someone was moving furniture in a distant floor.  Odd.

I do have a concern about build quality.  The stitching on one earpiece was slipshod.  It was worthy of a cheap garment.  I would have concerns that the stitching would not hold up with regular use.  I posted a picture of this defect below.  The most significant defect is the battery door.  It is too loose so the battery loses contact.  At first, I thought I was just having problems with Bluetooth connection issues or a discharged battery.  But then I discovered the the problems were solved when I would press on the battery door.  There is no fix for this, and I have to keep pressing the door.

Due to the defects, I will return my purchase.  And I will not ask for a replacement.  I will stick with my noise-blocking ear buds, even if they have inferior sound, because in a noisy environment like a bus or a plane, silence is a higher value than sound fidelity.  Had the noise cancelling been more robust, and if the product had no defects, I would have given it full marks after I received a replacement.

The tonal quality is very nice. Not exaggerated bass. These are the second set of the same buds. The first was a gift, fell apart early, and had no purchase info. But the audio and noise suppressing quality was so good, I bought another. I have documentation if these are faulty.

I'm changing the review back (this is the third time) to five stars. I had a few problems with my rechargeable batteries. They were no longer supplying the right amount of "juice" and the noise canceling was keep turning itself off (thus interrupting the sound) although according to my multimeter measurements all my rechargeable batteries were charged enough.

In a nutshell, the headphones are great. Build quality is great, they feel very sturdy but are prone to scratches. The sound quality is outstanding, bass is very deep and the "hi-s" are also decent. The noise cancellation feature leaves up to the hype and outshines the Bose QC3 headphones (these are German quality after all). I can tell you the noise cancellation is outstanding. I work in a server room with over 400 systems running and the "hum" is greatly reduced by these headphones.

People leave uneducated and uninformed comments about the noise cancellation technology. No, noise cancellation will not block your peers voices, your toddler's screams or your spouse yelling at you. It is supposed to cancel repetitive linear patterns only such as fan/engine noise, hiss etc.
