Tiny Versatile 2.5mm Male to 3.5mm Female Adapter with Lock/Unlock Feature : Extremely Versatile for Attachment to headsets/Devices with 2.5mm Audio Port.

I'm glad this adapter exists! The adapter works fine with the vmoda boompro mic and my Sennheiser headphones. It is a little difficult to push in all the way in but it will snap/click-in with a little pressure. Just be careful when you're pulling it out from the headphones because there is a little resistance.

Allows my sennheiser 560 S to work with the v-moda boom pro. This converts the locking 2.5mm port to a 3.5mm female port so my sennheiser can act as a headset. Works well on day 1. I will update my review if it stops working or I have problems, but so far it works exactly how I want it to. Update: still great

I was hesitant to buy this product because $18.49 seems like an awful lot for a simple adapter. But "buy nice or buy twice," right? I thought that at least the price meant that the product would be made robustly with quality materials. And it worked perfectly—for just over a month. Then I started losing sound in one side of my headphones. Checked the headphones, checked the cable, and confirmed that the problem is with this adapter plug. And this is just with normal use, no pulling or jerking at the plug. I thought, that's okay, products can have defects; I'll get it replaced. But unfortunately I was just outside the window of accepted returns on Amazon for this product (one month). So, I did as you would probably do, and I emailed KOKKIA and asked to exchange or a refund. It's been several days now, and I haven't heard anything back despite their guaranteed 48 hour response. I'm not typically a review kind of person, but I was so unimpressed that I had to warn others. It's an expensive product of cheap quality, and there is terrible customer support. I will be avoiding KOKKIA in the future, and my advice would be for you to do the same.

Works and fits fine in SHURE SRH-440 studio headphones, but it is too small to "twist lock". I just used a few drops of hot glue gun to secure it permanently into headphone socket. Works great with V Moda headphone mic cable.

Works perfectly with my Sennheiser hd560's, but very snug on my Sennheiser momentum wireless 2's. Used for voice capabilities paired with the vmoda mic

Seems fine at first glance, I appreciate how little it sticks out from the headphones (senn 598). That was something I was looking for, BUT the female end is loose so that the male end connection spins loosely and freely. Not sure if I'll keep it because of this.

I don't have very much to say about this thing. It does what it needs to do and makes your headphones more flexible since it can now use a standard cord vs Sennheiser's custom cord. Had this thing for a few months and haven't ever really had an issue other than it being hard to really secure because of the port on the headphones themselves being hard to latch in. Recommend this!

Updating my review - after a day of test, the audio keeps cutting off with just minimal movement to the adapter. Get's annoying whenever the cord moves around

Ottimo adattatore, l'ho acquistato per utilizzarlo con le Sennheiser 560s che hanno l'attacco da 2.5 e l'innesto a baionetta

Needed a microphone for my ATH-M40x only to realise that the headphones have a locking mechanism that makes it hard to just buy any sort of mic, this adapter worked without any fuss.

There is an outer casing on this that detached itself from the rest of the adapter as soon as I tried to remove it from my Audio Technica Headphones ATH-M40X. It is now stuck in the headphones. When I try to unlock it, there are some scratching sounds which I assume is the outer casing free-spinning but I am worried this could damage the headphones.

Das ist der bisher kürzeste dieser Adapter, die für die Kopfhörer mit versenktem 2.5mm Input und Lock-Mechanismus (Sennheiser HD5**-Reihe, Audio-Technica, AKG K361, usw.) die Möglichkeit bieten 3.5mm Kabel anzuschließen, der mir bisher untergekommen ist. Ja, er ragt heraus - wie man am Beispiel meines HD560s sieht - aber deutlich weniger als alle anderen, die ich kenne und er behält die 6.3mm Durchmesser auch über die ganze Länge hinweg bei. Der für mich größte Pluspunkt ist, dass er den 4-poligen Stecker 1-zu-1 durchreicht zu der 4-poligen 3.5mm-Buchse. Das ist evtl. etwas exotisch, aber die Sennheiser-Kopfhörer der HD5** Serie (z.B. der HD560s) sind teilweise intern symmetrisch aufgebaut und man kann sie mit echten 4-pol-Steckern und passenden Kabeln an symmetrischen Verstärkern betreiben (mit der 2.5mm-TRRS-Belegung T=L+,R1=R+,R2=L-,S=R-). Ein "normales" 3-poliges TRS Kabel funktioniert dann natürlich genauso gut in der 4-pol-Buchse. Der Adapter ist nun mal "nur" primär Plastik und recht teuer aber er ist relativ(!) winzig, scheint auch robust zu sein und ist eine absolute Ausnahme mit echtem TRRS-Stecker und -Buchse.

これ探してた！！どこのメーカーも出していないから、これ一択 こういうのでいいんだよ おかげで高品質ケーブルが無駄にならないし、選択の幅が増えていい事尽くめだわ( '∀｀)bｸﾞｯ!
