Worth it
A good upgrade. Lets the headphone amp output at full power. Also, seems more robust that the regular cable and less likely to get tangled.

Improvement over stock cable
The cable is an audible improvement over the standard 3.5mm one that comes with earphones - this was clear the moment I started using it. My player is a high resolution music player.

Makes A Noticeable Improvement!
Compared to the 3.5mm cable the balanced 2.5mm cable has a noticeable improvement to audio quality when powered from a decent amp (on Etymotic ER4SRs). I was able to test using an identical setup as my amp supports both 3.5 & 2.5 output therefore the only change was the cable. Very happy with my purchase.

The only real option
This is basically the only readily available option if you want a balanced connection with your Ety's

Definitely an improvement over stock item.
Very pleased with these. There is an overall improvement in presentation of the audio to my brain. Running from Astell Kern DAP giving a very pleasing output. I have been using Etymotic for years and find them the only IEM for me as they 'fit'.

Attention, à savoir : J'ai commandé ce casque jack 2,5 mm Etymotic pour mon ER4SR, et j'ai acheté plusieurs adaptateurs audio jack 2,5 mm vers 4,4 mm ayant comme ampli-DAC, un ifi audio HIP DAC V3 et un ifi audio ZEN DAC V2. je croyais que le problème venait des adaptateurs made in china commandé sur Amazon mais j'ai eu le même problème avec l'adaptateur dédié vendu par Ifi Audio (en forme de "T") : le son à chaque fois était très resserré, comme monophonique et plus fort du côté de l'oreille droite ; le même rendu avec les 3 adaptateurs. Le problème vient donc du câble car celui-ci ne doit pas être conçu pour être utilisé avec ce type d'adaptateur. J'ai sollicité le support Etymotic qui ne sont pas compétents décidemment.. : "Nous ne vendons pas d'adaptateurs et je ne peux parler que de nos produits. Je vous prie de m'excuser pour la confusion et l(impossibilité de vous aider.) Lorsque j'ai acheté le câble à 66€, quelques jours plus tard, il a augmenté de 22 €.... Et bref vous n'aurait pas d'amélioration audible en passant d'un câble asymétrique à un câble symétrique hormis une augmentation du volume sonore. Donc retour de ce câble.

My FiiO M11s sounds best driving balanced phones. This cable allows me to use my favorite Etymotic IEMs in balanced mode for a great optimized combination.

Comprei para usar com meu DAC Qudelix 5k, mas o som fica baixo do lado direito e o estéreo fica comprometido. Não sei se foi um defeito isolado mas vi outra avaliação aqui com o mesmo problema. Não recomendo, passe longe desse produto.

標準で付いてくるアンバランスケーブルがそのまま2.5mmになっている感じでいい感じです。音質についてはバランス接続のおかげで標準ケーブルより力強く鳴ってくれます。

Although these cables don’t fail as often as the cheaper etymotics earphones that the cable cannot be replaced on, these cables will still eventually fail if you use them while travelling like I do. Buy two and don’t worry about one failing and then having to wait for another one to come
