Original Nokia Audio Adapter AD-52 3.5mm to 2.5mm

I bought this to pair with my Sennheiser HD 598 C's, after removing the locking mechanism, so I could use any 3.5mm jack. This fits properly and works well, but I had to first take off the black rubber wrapping, otherwise it wouldn't fit. There are other people here that have posted pictures of it fitting without doing anything, but for some reason it didn't work for me, hence the reason to remove the rubber. It's very easy though, it comes right off, you just need a knife or scissors to make the initial incision.

This adapter works as advertised, and is currently the cheapest compared to all other 'flashier' looking options on Amazon, and does NOT have issues with functioning and contact which is much more than can be said for some of the other offerings. So... a simple 5/5 stars.BIG WARNING FOR THOSE MODDING SENNHEISER HEADPHONES WITH THIS..If you're looking to mod your Sennheisers (558, 598, 598 cs) to work with a V-MODA Boom Pro Mic or any other 3.5mm input plug... this is THE adapter you need, but DO NOT listen to ALL of the instructions you will find online on YouTube or in a lot of these other Amazon reviews for that matter.Now I am sure you're all aware that you have to remove the locking mechanism, and have done so. While you do that, PLEASE DO NOT follow what majority of the instructions tell you to do and remove the Silver Plastic around the plug hole for the headphones to make the adapter fit inside.Removing the Silver Plastic basically makes any kind of plug that goes inside the headset to be loose and not supported very well after the locking mechanism is removed. The only thing to really support any plugs that go in beyond the little chip and the tiny input jack soldered on to the chip, is well.... nothing, except at least a millimeter gap between the now much bigger hole and the plug shaking loose.... It's not a comforting thought.At least with the silver plastic for the headset left in, there's much more immediate point/surface of contact for the cable's plug to soften the blow should it be given any violent/accidental tug. Without the silver plastic left in, the cable being violently tugged could rock sideways enough as there's a big loose gap between the now far bigger hole and the plug that you're potentially dealing with a big problem.THE SOLUTIONWhy do any more damage to your $100+ headphones (you're already required to remove the internal locking mechanism), when you can mod and tear apart a far cheaper component instead? The less-than-5-dollars costing adapter you just bought.The adapter has a rubber/silicon casing, the black casing thing around is. The actual adapter underneath the black casing is just like any other adapter, in that it's a metal tube like the other adapters you see on the market. This means you're more than safe to take any kind of sharp knife, scissors and simply cut/peel the casing of the plug with relative ease without worrying about damaging the inside. Simply slice a line down the casing, and you will find it simply peels off. Just don't apply the kind of pressure you would for cutting with a bolt cutter and you will find it's very very easy to remove. People mentioned exact-o knife, but I found even my household scissors held like a knife was easy enough to peel off the rubber/silicon black casing around the plug.Once done, the adapter will be slim enough to slide right into your locking-mechanism-removed pair of Sennheiser headpphones without having to remove any additional parts.I hope this warning discourages people from removing the silver plastic from the headphones for modding their Sennheiser headphones. For the rest of you, enjoy, it's a lovely product.

Changing my review after doing some tests after issues with some audio. Apparently the adapter interferes with the left earpiece, which I thought was a phone issue with me but I have come to realize it's an issue with the actual adapter. So far this is the best adapter i've found on amazon for under $4, so if you want something that actually works you are gonna have to purchase something more. Do not recommend at all, if it actually worked maybe I'd change my review.

I cannot give it less stars because it is presumably not the fault of the plug. My cordless (Panasonic) phone has a 2.5mm female, so it fits. But, the mapping from the 3.5mm headset with mic did not work on the mic part - the headset part was fine. This is presumably the fault of the phone with something about the way they map the plug. Frustrating because the phone does not mention what they expect it to be mapped as. But, beware before you use this that it may not work.

I bought it for my bose qc25 as an adapter converting regular 3.5mm aux (that I always use) to 2.5mm end. Worked just great, but you have to try and remove the black cover (the one has NOKIA logo on it) that is covering the adapter to make it fit in your bose qc25

This is a small, lightweight 3.5mm to 2.5mm audio adapter. I bought it hoping that I could use it with a pair of normal headphones with my Panasonic home phones. No dice. I could hear the other person but they could not hear me. This adapter works great for things like modding your Sennheiser HD 598 headphones. Just dont' buy it thinking it will work with your average home phone setup.

Works great for use with Sennheiser HD 598 headphones and V-Moda BoomPro Mic after removing the locking mechanism from the headphone jack. Perfect solution for gaming. This adapter is still kicking it over a year later with no issues so far. Sound quality is great, having zero issues with headset or mic audio.Side note, I used a sharp exacto blade to remove the black Nokia branded rubber casing from the adapter so that it easily slides into the headphone audio jack without having to remove the silver plastic sleeve housed in the headphone audio jack. (You can also use sharp scissors to get a more evenly distributed cut, just don't scratch the metal casing of the adapter.)I prefer this solution much more that using the AntLion ModMic as there are fewer cables to deal with and the V-Moda mic also has an in-line volume scroll wheel. Much better comprehensive solution IMHO.

If you're buying this it's likely because you're using it with Audio-Technicas or Sennheisers in order to use your own 3.5mm cable or the V-MODA BoomPro for gaming. You can look up videos on how to remove the cable locking mechanism, but for Sennheisers do NOT remove the silver plastic thing in the plug, leave it alone. It's easy to just take a knife or something and prick the plastic rubber whatever off of the Nokia adaptet and peel it off with your fingernails, and it'll fit the headphones. After you do that, I can confirm it'll work with whatever 3.5mm cable you put into it, including the V-MODA BoomPro. You can also just remove the adapter and the stock Sennheiser cables will still work, just without the locking mechanism.

Es war wieder ein Bequemer Einkauf! Das Produkut ist genau so wie ich es mir vorgestellt habe. Alles besten gelaufen.
