Price savings is worth the slight difference in quality

These are letter sizes and not legal as the length is too long to hold a legal size folder.  But the plus side is since it is longer, you can store more folders in it.  The quality of the file box is slightly lighter  than some of the more expensive ones, but the price saving is worth the small difference in quality.  The top opens from a fold in the middle which is also convenient.  All in all it is an excellent trade off and I would recommend it.

So I bought these from online shipped from China, there was a long delay but contacting the seller who was very courteous, they had high demand for these from manufacturer and were able to speed up my order and provide me a small refund for delay, which was a nice gesture.

Once they arrived a week or so later, I plugged them in from my Xindak 8 DAC to a pair of studio monitors, Emotiva Stealth 8's, thus the RCA to XLR running in unbalanced mode.
I played some alternative, electronic/dance and jazz music. I observed a marked improvement in the frequency response, it was unexpected but I was easily able to hear the difference, the highs appeared to be crisper, mids broad clear and voices a little more distinct, softer vocals came through a little more. The lower bass frequencies seemed punchier, again more distinct. The music just appeared to sound better, like I'd rolled in a holy grail pinched waist Amperex tube into the Xindak 8. It was like having a veil lifted once again.
I've used the lower end Kimber Kables and other high/mid range cabling, but I was surprised to hear this marked a difference from fairly affordable silver coated cabling. The cables themselves were thicker and heavier than most RCA's, a little more rigid too, so if you do need wire in very tight spaces you may need to aware of this. There's a trade off for improved sound, I didn't feel a little bulkier or heavier was a bad compromise, in truth I was expecting a little of this.

I think ZY Hifi have a good product that allows you to hear a marked difference and I hope others get a chance to listen to equipment through these. The transparency of the overall system will matter somewhat for amount of improvement, but like anything it's trail and error practice. There are other silver coated copper core cabling brands out there, priced much higher, but likely not as affordable as these for improvement they make - great value.

Disclaimer: I have absolutely no relationship with the manufacture or seller, nor am I in audio business, I just had a good experience with both product and seller.

Inexpensive compared to others costing more with little or no difference in performance.

I am finding the quality of LD to be worth the price difference compared to some cheaper options.  It arrived quickly as expectedf

I've bought these colored headphones in stores on and off for years, so I was excited to see them on Amazon for such a low price. I'm pretty sure they aren't the same as the ones I used to get.  They definitely have a cheaper feel.  I feel like some of the reviews on here are probably for ones that were not purchased on Amazon, like the review that said the speaker part on the headphones popped out - that used to happen to mine.  These don't look as though it will be as likely to happen but I have only had them a week, so we'll see.

These are different than I was used to.  The color is much duller (although still pretty) and most importantly, the ear buds have an odd shape to them where the part that goes in the ear sticks out a bit.  You can kind of see it in the picture.  I suppose this is done to help them stay in, but it feels kind of annoying and take some getting used to.  If you are used to a more round shape, you may not like these.  They are hard plastic, as another reviewer mentioned.  Sound quality is also not great.  I do notice a lower quality than the standard Apple headphones which I was using before.  For my purposes, however, they are just fine.  I am not very picky about sound quality and it is acceptable, and they are a great price... I love the color which matches my iphone's case.  You have to be aware that at this cost, you aren't buying great quality anyway.

It works as well as the more expensive, and I saved more money

These ear pads are slightly different than the factory originals, particularly with respect to the interior diameter, which is very slightly larger than the original ones. At first I thought the differences would be noticeable, but I replaced only the left ear pad and after several weeks of use I'd have to say that any differences have been insignificant.  Given that these replacements cost much less than the official ones and seem to perform just as well, I'd have to say I am pleased. The one factor I cannot yet evaluate is how long they will last compared to the originals, although there does not seem to be any reason to expect a difference in durability.  Performing the replacement is easy: one yanks out the originals, pulls off the film to expose the sticky surface, and inserts the new pad into the headphone--it is essentially idiot proof.

Does what it is supposed to in a more economical manner, with the same quality as the higher priced filters.

I saved a good bit buying the mount here and don't have any complaints.

Better than paying half-again the price for the same item.

We noticed a small difference using these cables. The price was right. But I think you can find the same thing at Best Buy, Home Depot or Wal-Mart for the same price or less (and no shipping).

noticed a small difference in performance right away, could feel how much better quality this filter is compared to stock

Sometime you question whether shelling out the extra bucks for a component like this can really make a difference.  In this case, yes, it does.  I highly recommend it, it will be quieter and shift better, guaranteed.  You can find it cheap enough on the Amazon marketplace.

Did not notice a power difference, but the savings from air filter changes is worth it alone.

No promo/discount given

They actually work, seems to be a very slight colour difference between the two I put in, but for so cheap you can't complain. I'll try to post back when they die.

There is not much to say about replacing an electronic component part, except in this case the technician did recognize that this new product's display on the computer screen was indeed sharper and clearer than the one it replaced.  Therefore, it certainly was an improvement.  The price tetered upon the threshold of my acceptance or rejection regarding the cost/benefit analysis in that the amount paid was about the maximum that I would have allowed, and if it were any  higher I would have scrapped the laptop.  This repair/part replacement simply extended the useful life of the unit for a few more years.  This laptop was my only computer until I upgraded to a much better quality laptop in March, and it has been relegated to "secondary spare" status, but is ideal to take on vacation, as it is compact and easy to pack and transport.

They are definitely a bit larger than the standard, worth the difference in price.  But don't expect to save a whole lot of time.  You'll still change cartridges pretty regularly.
