Youkamoo4 Pin XLR Balanced Replacement Upgrade Cable Compatible for Sennheiser HD650, HD600, HD660S, HD660S2, HD580, HD58X, Massdrop HD6XX Headphones Balanced Upgrade Cable XLR4

The cable is well made, and the sound is better than OEM. It brought new life into my HD580 headphones that are from the 1990's. One mod that I had to do was to squeeze glue into the end where the cable goes into the connectors. They have no strain relief on the ends. I saw some reviews, were the cable pulled out after a few months. I may buy an extra set.

This cable is absolutely outstanding! The audio quality is far "Superior" with this on my Hd 660S compared to the stock cables. The soundstage is wider and way more spacious compared to the stock cables, instrument separation is way more spacious, detailed and cleaner, compared to the stock cables, I guess using silver lining instead of copper really makes all the difference......the base is deeper, tighter and punchier, and the treble is far Superior compared to the stock cables, it's more detailed, sparkly and airy! the mid range is far more crystalline and cleaner with vocals and horns especially sounding more colorful and resonant!Overall this is an absolutely worth it purchase!

Excellent! Real value for money here in which I think I got the 85 dollar version instead of this one. Comes with a carrying case and a pouch to carry that! then there's a high end leather cord wrapping holder that says premium. The cord and adapters are high quality and you can hear the difference from other balanced cords. I have 4xxxs and a balanced cord from another dealer and the quality compared to these is night and day. The cord itself is nice and doesn't roll up on ya and is adorned with stuff that are not on the more expensive 4xxx cord. Example is the cords at the splitter leading to the cans has a round stopper that can adjust to keep the split cords neat and tidy along your head and neck. I am very happy with my purchase. Interesting note, I had to buy this item twice because of a package pirate. If the price was like my other cord I would not have risked rebuying something unknown to me. The price point really is this great selling feature and I hope people figure this out and they sell millions of these because they deserve the success. I salute these guys and would buy there products again. T.

I love how this thing looks. its quite light. Don't have much long use on it yet so I can't say anything about durability other than looking at the build quality. I would not say its a super strong cable but it seems about average. I would never use this cable on the go, It seems too fragile. I think there is a lack of heatshrink / support near connection points, I personally would sacrifice aesthetics by adding some there., those areas will wear out first. Otherwise, good value for money. Using with HD 600

I purchased this cable as an option to go with the Sennheiser HD660 S2 since they don't include an XLR connection. I wanted to try a cable with an XLR connector to go along with a DAC/Amp combo I recently purchased. In honesty, the difference in sound between the standard unbalanced TRS cable that came with the HD660 S2 and these is negligible (to my untrained ears). The main benefits that I get from this cable is the fact that it is truly non-microphonic from end to end. The cables that come with the Sennheiser pick up annoying bumps, scrapes, etc., straight to the cups. This cable doesn't have that problem. Also the cable is longer, so I can sit back in my chair without the cable tugging.It comes in a plastic travel box and the cable is inside a leatherette pouch with the connector inside of little ziplock bags along with a leather-like strap to keep the cable neatly rolled up when not in use. Very nice touch. Also, appearance-wise, I like the braided encosure of the cable-it also compliments the bronze branding on the HD660 S2. Nice touch.My only wish would be that the connectors to the cups should be something other than the clear plastic. It's hard to see which one is left or right and it cheapens the look a little.

A/B test your cables guys! People say it's snake oil but you can hear for yourself that it's not. I've tested out 7 cables and they all affected my audio in many different ways. Here are my reviews for them ranked from best to worst.#1. $21.59 | Youkamoo 8 Core Silver Plated (3.5mm) - Grey- This one was almost a night and day difference from the OEM. I immediately noticed how my songs opened up and the highs just sounded so nice and sparkly. It wasn't an increase in treble but more that I heard details in the highs that I've never heard before. For example, I can hear these subtle mouth noises a singer makes when they sing that I never noticed before. It was almost mind-boggling. I definitely hear an increase in soundstage and detail overall. The lows sound the same and the midrange/vocals sound even better.#2. OEM Sennheiser Cable- Surprisingly the OEM cable that comes with the headphones sounded better than most of the 3rd party options I've tried.#3. $15.99 | FAAEL HD600 Cable (3.5mm)- This one sounds really close to the OEM cable that maybe it should be tied for 2nd place. I could've just been biased towards the OEM cable because I've used it for so long, but I would say the OEM cable just sounded ever so slightly better. Compared to the #1 cable, this one just had a little bit less detail and it didn't add that sparkle that the #1 cable adds. Overall, it was just a tad bit harder to distinguish and pick apart instruments during choruses.#4. $23.99 | Youkamoo 8 Core Silver Plated (3.5mm) - Black w/ translucent connectors- This one looks the same as the #1, apart from the color and the piece where the two cables fuse into one. But it didn't sound as good. It was noticeably less detailed and worse than the OEM and the #3 non-silver plated cable. Can't really explain it other than it just didn't have that magic that I was looking for.#5. $16.00 | NewFantasia Upgrade Cable (3.5mm w/ 6.35mm adapter)- High are noticeably degraded and lows are less extended. The soundstage is definitely narrower and not in a good way. This cable just sounded worse than OEM.#6. $29.35 | Hilitand Cable, Double Needle 8 Core Balanced OCC Silver Plated- Overpriced and you can buy the same cable (see below) for 1/7 the cost.- Either this is a poorly implemented silver plated cable or they're outright lying. The audio sounded so grainy and my songs lost so much detail, especially in the highs. Hi-hats and cymbals were hard to distinguish and vocals lost their airiness.#6. $4.35 | Double Needle 8 Core Balanced OCC Silver Plated Audio (Same as above)- See the review for the Hilitand cable since this is literally the same cable for 1/7 the price. They both sounded exactly the same.

They arrived a few weeks earlier than expected. I've only used them for a week but will update this review if my initial positive sentiments change.

不注意でHD25のプラグを壊してしまったが、以前断線した純正ケーブルをまた買うのも面白くなく、ちょっと贅沢だけど評判の良さげなこちらを購入した。DJ用途じゃないので左右対称でも問題ないし、ついでに差込口を下向きに変更しておいた。交換した直後はシャリついてとても聞いていられず、失敗したかなと思いつつクッションを挟んで大音量で一晩放置。翌日着けてみたらやたら低音が濃くて解像度も高いヘッドホンに変身していた。なにこれ？ドライなHD25から正反対の音に大変身ながら全然嫌じゃないどころか明らかに純正より良い音だしこういうのもアリだなとは思うけど、元の疲れない音も捨てがたいので次に交換する時はおそらく純正ケーブルに戻すと思う。

HD650の場合、標準ケーブルに比べて高音が出て低音が減りバランスが普通寄りになります。HD600、HD660sも高音寄りにシフトするので純正の音から変えたい場合にはお勧め出来ますが、バランスをそのままにグレードアップさせたい場合には向かないと思います。

Beautiful cable, seems to be working flawlessly so far. Comes with some extras as other reviews have mentioned, they’re very high quality and a nice little surprise! Sounds noticeably better than the stock, single-ended cable that comes with the HD600, and looks much better. No complaints at all considering the price

I can't complain for the price. It is a little on the short side(Shorter then advertised), and the finish on the connectors going into the earcups leave a little to be desired but other then that it is a perfectly good balanced cable! I don't notice any sound difference between this and my more expensive NewFantasia cable.
