The ear pad on a set of USB headphones had worn off.
These have been used every day since the pandemic, eight hours a day, 5-6 days a week.
I needed either a new set of headphones, or... something.
I already had another pair of headphones, but it used a standard phone jack, not USB.
Due to software constraints, using the computer's female phone jack socket was not an option.
New headphones? Or an adapter?
I decided that the adapter is worth the price, rather than buy a new set of headphones.
The Dukabel (funny name!) came up in my Amazon search so I went for it. It arrived ahead of schedule.
At first the phone jack would not click completely into the Dukabel adapter's female socket. But I tried it a few times and it fit snugly with a confident snap. The USB connected just fine, and both audio channels came in crystal clear.
When I had my first remote meeting with my work team, they asked if something changed, because my voice sounded so much clearer!
So at that point I know I made the right choice. The right adapter made all the difference.

The reason I wanted this product was because my laptop lacks a mic input and I wanted to get some kind of inexpensive audio interface that would allow me to take an auxiliary cord that I connect to my Nintendo Switch's headphone jack and record the audio from the Switch directly to my computer.

That said, this product did allow me to do that - I can hear and record the output of my Switch from the computer. The audio itself is crystal clear.

However, I did notice two things that I will need to update this review about in the future.

The first is that, there seems to be a lot of background static coming from the device. This can be due to many things, but I know it's not Switch because it's not there when using headphones on the switch. It's either the computer or this interface.

Now, it's not so much the static is absolutely unbearable... it's just more than you are expecting - really I feel like there shouldn't be any static because there is no true mic going in which would often be the source of it. I am using a TRS cable and not a TRRS cable, but that shouldn't matter as there is no mic output from the headphone jack... it's just stereo output.

Also, I did notice the volume seemed kind of low at first - and wanted to point out that if you navigate to the driver properties of this device, and check the 'Custom' tab, you may see a 'AGC' checkbox (Automatic Gain Control). The moment I checked this box - the volume immediately jumped to full line level and the static is much less obvious against the full volume of the Switch. Even at these levels, the audio by itself was crystal clear.

This will work for now.

Considering this was a $10 item as opposed to spending $30, $50, or even $100 to get a more production level audio interface - this was a great value to do what I needed.

That said, something I didn't consider is this device can't take the stereo sound of the headphones and keep it stereo on the mic side... the cable is expecting a mono mic... so the stereo is lost on the way in.

I'm okay with this... I didn't really need the stereo for my purposes - but ideally I would have it. It's not the devices fault - but for anyone else that might use this device like how I did - you may want to instead get an auxiliary to L/R RCA adapter and route the RCA to some other kind of interface. That would be more appropriate.

I did email Dukabel about that static issue and am waiting for a response. Will update in the future about it.

Update:

Dukabel responded to me (apparently from their Marketing Director) - and they wanted to make sure I was absolutely satisfied but felt that given how I am using the product in a way they didn't intend for they offered me a full refund and told me I didn't need to cover the cost of shipping.

I politely declined their offer because I can still use the product for what I needed and the problem I was having with it was something I could overcome.

I must say - I was not expecting Dukabel to be so responsive and supportive - because to me they are a company offering fairly simple products and probably don't have the full resources of other larger companies - yet they went out of their way to assist me.

I'm in the process of email exchange with them to see if the static is really something on their product or my computer - because one of the tests I ran showed the static was present without any input. So it's not having to do with what or how I connected it - it's either the interface or my computer. It really could be either.

But I still recommend this product especially if you are using it for the purposes they designed it for. If it really isn't working for you, it'll just mean you will have to look elsewhere and should easily be able to get a refund.

Unfortunately, I can't comment on those needs because I'm not using it that way.

The overall quality. Excellent.

Headphone jacks don't work on my PC so this is perfect.

I got a different one earlier with a speaker and microphone input. I don't know if it was the model or my computer, but there was a hum. I got this one which is only speaker port and it works very well after one day.
