I have an HD650 with stock cable (3.5mm, 6.3mm) and a Tripowin Granvia (4.4 mm termination) and to pair with my source (iBasso Dx220 Amp 1 MK II) i needed this cable. I had researched a lot and most of those cables were either expensive or aesthetically not good (bulky). I had read about the ear audio cables which were made in India and heard very good reviews about them from various forums. TAS had them in stock, and it was a seamless experience buying from them. The delivery happened very quick too.

The cable - Looks and feels it lasts a lifetime, the terminations are made really well, no flex whatsoever when connected. I'm able to enjoy the HD 650 at its max potential due to this cable. Thank you Ear Audio, absolutely well made cable, and i love the name "Ear Audio" :-). I'd also like to get a 4.4 mm balanced to dual RCA (3 mtr) from you if that's available.

TAS ~ thank you for your quick and prompt delivery and very honest pricing. This may have been my first purchase from you, but this experience will make me lean towards more in the future.

Wishing you the very best Ear Audio. You guys compete with the best out there

Though I was a bit concerned to buy a dangling type adapter, the doubts were removed when it arrived. Very well made. good quality check and looks good too. Earaudio is also an Indian brand, so that's a bonus supporting a brand in a niche low volume area. Bought the 4.4mm to 2.5mm as well.

Compared to the expensive balanced adapters this one is quite nice in quality and does the job perfectly.

This works well. Quality is very good.

The Performance of this Balanced Adapter is Excellent.

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.
