Alright I compared the momentum on ears with 3 cables:
Ebay cable
Original On Ears Cable
Over Ears Momentum Cable
Source is the Hippo Biscuit mp3 player
Conclusion:
Over ears cable > One ears cable > Ebay cable
The ebay cable in comparison has a really blunt treble with poorer extension, losing most of its sparkle and air. The bass is also more focused inside your head and is thumpier and doesn't sound so smooth.
The over ears cable on the other hand sounds smoother overall with a more refined treble and is the best sounding among the three i feel with the widest soundstage overall.
However when i checked the Sennheiser UK replacement parts i saw that both the momentums use the same cable code.
After a month of use of the China cable, I have to give my 2 cents. First off, I have not tried the China cable with the Momentums. However, I have a/b all 4 of the Momentum and Momentum On-ear. My conclusion is that the cables with the inline controls do sound slightly quieter in comparison to the straight, but sonically speaking they are identical. I have to concur with Sennheiser on that the cables are identical.
Now on to the HD598s. I love the new cable! It fits so well, both physically and aesthetically. The cable itself is of high quality construction, something that I was worried about. The plugs and cable strains do their job extremely well when being stressed. I keep forgetting that the cable length is only 1/3 of the original so I keep reaching for things thinking I have another 2 meters of play only to yank, twist, or pull on the cable and headphones. Both have held up well under my blonde moments.
Sound quality with the China cable is actually slightly better than the stock. Upon first plugging in the China cable I was surprised at the difference. I know most of you have noticed no change, but I actually find that there is
subtle, yet noticeable differences. I was not expecting this as I purchased the cable for it's length, yet
to my ears I immediately noticed a difference (for the better). I didn't order the cable from eBay or Amazon. I purchased it locally from, ironically enough, a Chinese fellow selling the cable on Kijiji. He was using the cable with his HD558 before he upgraded and at the time of purchase told me that he thought the new cable did sound better. I thought nothing of it until I got home, plugged it in and resumed the song I was playing before I left (Gjermund Larsen (1981-) - DIPLOM - folk suite for fiddle and string orchestra by Trondheimsolistene). "No..." I thought, thinking this must be a placebo effect. I plugged in the stock and pressed play, then swapped it again for the new. Ok, this is interesting. This is what I found:
Bass: No difference in extension, but it does sound fuller with more body and air. This is most noticeable with strings.
Mids: No change noticeable.
Treble: A slight extension in range, and like bass more air. Female vocals sound more 'sweet' when hitting the higher registers, and cymbals gain a little crispness.
Soundstage: A noticeable improvement, probably the area that gains the most. Not wider, just a whole lot more open; more air.
As stated I have been using the new cable for the past month. The past couple of days (in between my Civilization: Beyond Earth games) I have been a/b the stock and China again. I figure I have been using the China cable long enough to notice any changes over the stock. Again, I immediately notice the
subtle differences.
Here is some headphone pron (yes that is spelled right
) for you good folks!
