These are great.  I have the PE700ii (just like the PE770 except it plugs directly into the computer via USB instead of using a thumb drive) as well as the SE400, and I use them in both with great results.  I used to wind my own bobbins, and had tension problems and frequent issues with my bobbins, but these are not only super convenient but they work better!  I am a convert to these prewound bobbins, and the bobbin thread works great with brother machines.  I am loving these, hope you add black thread soon to your 90 wt prewound bobbins!

I bought these to go along with the&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/BEHRINGER-MICROAMP-HA400/dp/B000KIPT30/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">BEHRINGER MICROAMP HA400</a>&nbsp;and they work great. Nothing really to them; They just convert the smaller 3.5mm headphone plug to the larger 1/4 inch one.

I have a set of PS500e Grados.  After installing the ear pads, the sound of the headphones changed significantly: The midbass was accentuated and the highs were muffled.  To be fair, these are MUCH more comfortable than the original Grado pads but the trade-off of lower sound quality wasn't worth it for me.  They were easy to install and remove and are made of really good quality material.  I think a redesign of the foam pad where it is tapered, like the Grados, or a larger inner hole for the sound to come through, would make these perform much better.

Perfect replacement for my 12-year-old DT770s.  Now they're like new!  Amazing how much better they sound when the drivers aren't pushing directly on my ears!

Like other reviewers, I come here from the 730 series, of which I have two. After 15 months of full to empty battery usage overnight, every night, the battery in the main pair started to wear out, and I started shopping. The reviews on the Other 'replacements' were less than great, so I swapped to my other 730's to wait and decided to simply get another 730. Whoops, the -latest- reviews of the trusted and true 730 were going down, seems they cheapened them.
So I decided to try the 760s. This review is Only for the Amazon (Prime) delivered 760s, as the First pair I received (only one available) was actually a pair of 750s, and they were as bad as the reviewers said. No Aluminium bands, don't even unwrap 'em!

These are Very good, the controls fall instinctively to hand And use, my comfort sleeve fits them perfectly, they deliver the warm bass easier to find than even my 730s, (tilt them in your ear and try Every bud, even if it doesn't seem logical-the Smallest buds felt Too Large, the mediums turned out to be best, the large was softer, but presses as I move my head, my experience), very comfortable, recommended to all 730 owners.

Now if only Windows 10 didn't treat them like dirt (I must remove them from Bluetooth, re-pair them, make the Required enhancements adjustment (bass and loudness) Every Single Night! grrr.. but hey, they fixed the wifi/LAN connect-only-if-the-moon-is-full issue, so I'm sure they'll get around to it..

Still, worth the trouble and the Only logical replacement for the Original, not cheapened, 730s. Bonus? even More battery life! I have Yet to kill them with my over-night Netflix take me away from the ambient noise with a good documentary regimen (try West, it is Fascinating and lasts For Ever! I know more about the development of the Western United States than I thought possible, like learning a language in your sleep, LOL)

I bought with my husband in mind to use on the iPad 2 I gave him. I happen to really like them. The length is great, and they glide on the screen unlike some rubber styli. He took it and said this will be great for his desk  top pc, the touch screen monitor is not easy to navigate as far as it has to be. So he found a solution with these. Somebody has to go with out a tether because you only get 2, but he won't need one. The tethers are great, they work great for my kindle and my Windows tablet Acer W510, just connect to ear phone Jack and you do not lose it. Great idea. Also extra nibs, they are like the Bamboo Stylus nibs but cheaper that 18.00 for 3, that was ridiculous and they fit each other's stylus. You get 3 include in this package, and a cloth for screen. I recommend, good deal. You can get 12 nibs for 6 and that is great when more are needed.

All of the hoops fit and worked perfectly with my Brother PE-770 machine.  I tested each one and they are all perfect.  In fact, I can't tell the difference between them and the one that came with my machine.  The construction is high quality and as I said they fit perfectly.

I bought these as replacements for my blade micro heli.  After a few cycles the heli flight were really short and I first suspected the batteries.  So I reached out to NanoForce for advice and they were very responsive and genuinely concerned that their product would not perform as expected for me.  It turned out that it was actually the heli with some misaligned parts that was at fault.  So I am flying the heli again and my park flyer happily and the batteries are actually great.  I think they are better than the eflite originals (but that may be an unfair comparison since they are quite a bit older).  The point is: don't hesitate to try them I think you won't be disappointed.

I originally bought these for a pair of Altec Lansing IM716 IEMS which they are great with, but I also tried them on my Etymotic ER6i and found they are the holy grail of ear tips for this particulate IEM.  On the ER6i, they are so comfortable you do not even know they are in your ear.  They provide the isolation you get with the silicone flanges or foam tips but are much more comfortable and sound GREAT! Something about the larger opening at the end of the tip really expanded the sound stage on the ER6i.  At $5 a pair, they are a little bit $$$ for the month or so each pair lasts, but not any more than what Etymotic offers.  The ER6i is not listed as compatible by Comply, but trust me, they fit just great.

I bought these for some Shure SE215s that have proven to be, by FAR, the most reliable ear buds that I've ever come across.  These foam sleeves are a little bit of an upgrade from my originals since these have a little screen inside them, which keeps ear wax out of the ear buds, great idea!  As for sonics, I've found these to provide the best bass response compared to the other tips I've tried, but also provide great clarity.

I bought these after my second pair of sony mdr-ex71s broke (one earbud went out). They are a definite upgrade from the sonys, both in sound and build quality. They sound similar to the ex71s overall, but high frequencies are less harsh and the bass is more under control. That's not to say the bass is lacking, these headphones are fun to listen to and have plenty of kick to them (I listen to mostly electronic and hip hop).

In terms of build quality, the aluminum housing is great and feels more robust than the sonys plastic body, yet they're still light enough to forget you're wearing them. The cord is stiffer than the sonys and has a cheaper waxy feel to it compared to the rubber of the ex71s. However, the ex71s cord is notorious for degrading over time (both of my pairs did) so hopefully the denons don't suffer the same fate. The cord is very microphonic, so these headphones are the best when you're relatively stationary. The rubber tips make a good seal with your ear and stay on the earbud very well. The tips on my sonys would fall off all the time and I'd have to go searching for them. The denon tips have yet to come off at all.

Overall these are great headphones, especially for the price.

I love them.  They are small, but feel good in the hands.  These are leaps and bounds above the cheap plastic knock-offs.

They work great with RetroPi, as long as you don't overcomplicate the installation.  Be sure to apply the firmware updates before you attempt to pair with Bluetooth.

These work great, and are nice and flexible.

I highly recommend these. I've been using them for 3 years now and they are outstanding. Just watch the pricing here... Sell for about 44$ in a sport shop and your not paying shipping. If your a Prime user, not so bad.

These works just great! The only problem I have with it is that sometimes the plastic connectors can break. Just be careful to not twist them, and you should be fine.
I think they should pack an extra 2 or so of those connectors just in case. I bought an extra set to expand my original, so I ended up with a few extra.
