Sennheiser CX MOMENTUM True Wireless 3 Noise-Canceling Earbuds

When i am use this dac in my iem, sound quality much better and improve. Nice product.

Fitting is OK. But earpads could be much softer. Other than that go for it.

This converter is excellent, recommended. I have tried this with even a locally made earphones and also branded. It really made lot of difference in quality. Price tag is also reasonable, worth buying recommended.

I have piston fit. Later I bought edx pro(just a curious bug in head to try iem), then I wanted to buy 1more single driver. But unfortunately it's not available on sites these days. Then I stumbled upon demo section. I saw these earphones. I bought them. They came in excellent condition. Sound is really a big upgrade over piston fit. Music listening is more fun. Guitars felt a little low. I listened to the long after you've gone. Guitar strums were not that joy giving (compared to edx pro). Mahaganapatim by the priyarang project . Initial sounds I don't know what they are called;felt so good. I could feel the sounds coming from different positions. Thank you.

Those who are looking for 2.5mm male to 3.5mm female convertion adapter please don't go for this. This adapter may be only used with the particular sennhizer Headphone only.

Good quality convertion cable from 2.5mm male to 3.5mm female, served the purpose very well.

They are very good performing in all genres of music although not bass heavy. Although would like to see how they test against time with build quality and all.

Excellent Cable worth for price

Nice and sturdy case ideal for storing IEMS/earbuds & cables on the go.

This is my first IEM purchase. To be honest the sound quality is way more than I expected. For beginners like it's ideal choice to test & experince.Hearing good quality music for past three months. Looking forward to develop and upgrade my audiophile experience. Eyeing on the next one. Will snatch the right one soon

Value for money, great iem for this price, as others have said in their reviews, these are good and leaves nothing much to be said.

first time ordering from the audio store, the packaging was nice, they included additional 2 pairs of black silicone eartips, which i appreciate very much!

I asked for replacement once I recieve the replacement product i will review again

Bass is very leaky , wanted a balanced tight bass like that of cx180 but not even close to that.
Fitting could have been better.
Can get equivalent tws /neckband for under 3000.

Very good product

TL;DR: EarAudio adapter is great, if you need balanced, go for it, its worth a shot.

Wanted to use my sennheiser HD660S with the balanced port of fiio btr5. I do use senns with ifi hip dac as my main driver, so just wanted to try the fiio balanced option. So, needed a converter which could convert 4.5mm male end of senns cable to 2.5mm male end (fiio has 2.5mm female input end for balanced connection).
Senns do come with 3.5mm regular cable so I had already used the fiio btr5 with senns (on 3.5mm) and was quite impressed with the output, but was still curious about balanced connection, so got the earaudio converter to give balanced a try and it was worth it.

The connector / converter (EarAudio 2.5mm male to 4.4mm female Adapter Cable) is of great quality, I don't think there's any loss in quality at all, at least while using with stock senns cable (which are already quite good). Serves the purpose well, build is great as well.

So, for someone who'd want a couple words about balanced connection, it's a hobby guys. For me, balanced (on fiio) sounded way better than single ended because fiio btr5 provides more power output in its balanced output than its single ended connection and secondly, btr5 balanced output is just way better in every way than its 3.5mm counterpart.

I used the adapter with senns hd660s, fiio fh3 (4.4mm balanced cable). For iems, its not that exciting to go balanced route as iem (in general) don't need that much power but if you have a full size headphone lying around which could use balanced, its worth a shot to try balanced (with something like btr5).

Caution: ifi hip dac also has balanced, but its balanced is useless for iem as it hisses a lot with iem, so before going balanced, make sure to read some reviews.

As for my iem, FH3 (with btr5), I'm using them with a balanced 4.4m cable which just changed the way it sounded originally. Fh3 with 4.4mm connection is a different beast, punches above its weight and in this particular case, the balanced connection was super worth it.
