Works perfectly with my 4.4 wm1a and se846.
Lovely quality and great shipping.
Absolutely wonderful experience

I order mmcx 2.5mm and 4.4mm cables for my Fiio fh3 and Magasooi k3 pro.
Really nice cable for good price.

Cables are very light and the connector are of good quality as well.

MMCX connector was bit tight to insert but once you have done the hard part the mmxc connection seems very smooth not too tight to revolve IEM's in socket or too easy to miss align.

The ear hooks are very light and gentle on ears as well.

Sonically I did not found any noticeable difference from stock cable, but i did felt some dynamics increase like bass felt bit more and highs were tad less harsh. But it can be a placebo as well, as i did not extensively do a-b testing for stock and C8 cable.

I bought my new iem moondrop blessing 2 so I am again planning to order this cables for 2pin connector as I miss these incredibly comfortable cables on my B2.

Thanks HP for nice/rare offers and products!

Static issues from day one (using with Shure Aonic 4) and I don't mean noise, the headphone would literally give an annoying (albeit mild) electric shock when listening on my PC due to grounding issue. The stock cable didn't do this.
And now after merely few months after I bought it, audio is cutting out from the left.

Moral of the story, keep your Chinese cable purchases under a 1000 bucks because they'll eventually fail and end up being a recurring, half-yearly purchase. Also, the same brand on Amazon is available for less.
Two stars because at least you can change cables with wired IEMs unlike disposable Bluetooth phones!

High quality and sturdy. Material feels good to the touch, this might be a placebo but the stereo separation is much better than my older cables.

Purchased this for use with Moondrop Aria. Its a bit tight, but fits perfectly.
Very lightweight and soft. Its a big upgrade over the stock cable that Moondrop provides.

Not a big change in sound, the only thing I noticed is that minor details are heard more clearly. Overall timbre seems improved. And left right channel separation is more apparent.

Also a big thanks to HPZ team for providing me Audiophile Playlist Cards with this purchase! :)

Been using this earphone for more than an year now, time for a review.

Build:
The handmade machining of the T20 metal housing is pure comfort on ears. Cables are tangle free and come with great metal support near molded areas to prevent damage.
Comes with interchangeable filters for bass, treble and mid range, to feel the difference distinctively one has to use an amplifier.

Performance:
Works well with high end Android's and iPhones with 16 ohms impedance but when paired the earphone with a Shanling UP4 amplifier, that's when the magic happens.

Low/Bass, Mids, High trebles all sound perfectly well. Can't get any better for the price we pay.
Lows

The lows were solid on the T10s, but the lows here seem to be even more powerful, even when using the flat filter. Switch in the bass-boost filter and it feels like the lows should be shaking the floor beneath you. Still, these are well balanced and never sound booming or overdone.

Mids

The mids are open and unrestrained sounding, with low-mid depth that we often find lacking in in-ears. There is no dip in the mids, though there is a very slight bump around 2 kHz that adds a perfect bite to electric guitars, making these excellent in-ears for rock fans.

Highs

There is a nice clarity to the highs that somehow never gives way to harshness. Hi-hat and cymbal work is well translated but even cymbal-bell heavy parts never sound ear-shattering. The whispered vocals on June of 44’s “Lusitania” are eerily clear and the T20s don’t exaggerate the sibilance.

The T20 is a powerful IEM and to me it is their best one so far. I am convinced the T20 is an earphone that pleases a whole lot of listeners, this is about as good as it gets in this price range without going to custom monitors. You won’t regret buying it.

Received the cable well within a couple of days, kudos to the headphone zone team.

Build:
The Tripowin C8 Cable's braided in a unique way with coper films around fabric based material giving flexibility and durability.

Performance:
Paired the earphone with Shure CE215 via a Shanling UP4 amplifier.

Low/Bass: Needs a whole lot of improvement in low frequencies.
Mid range: Earphones are great at midrange and have a warm tone, makes it a good listening experience, can change according to user opinion
Treble/high range: It does add significant improvement when paired with Amp, else no improvement at all.

Cables are a great purchase, value for money product.
