Headset BuddyLine-Level Input Audio Plus Headphone Monitoring with Built in Attenuator Adapter for iPhone, Smartphones (Mic-Line Plus)

The headset buddy (hereafter HB) totally works as advertised, but it didn't at first and I want to share with you the trick.So I was hooking up a PO-20 (don't worry what that is; it makes sounds) to my iPhone. First, I plugged the male end of the HB into the PO-20, hooked a male2male cable from the line out of the HB to the iPhone and plugged my headphones into the headphone jack of the HB. This enabled me to hear the PO-20 in my headphones but the iPhone heard nothing. Then I realized I had the HB backwards.So I plugged the male end of the HB into the iPhone and ran the male2male from the HB to the PO-20. That got the iPhone to hear the PO-20 but I heard nothing from the headphones. I loosened the headphone plug and jiggled it and heard sound. The problem? The headphones had a microphone (mic) built in.I inserted an adapter I had between the headphones and the PO-20 and everything worked as it should.If you look at the jack on headphones with a mic you'll see 3 black lines. These separate the jack into 4 sections: left, right, mic, and ground. If you look at headphones without a mic you'll see 2 black lines: left, right, and ground. If you look at a pair of mono headphones, or a single earbud, the jack will have one line: signal and ground.So the headphone jack on the Headset Buddy needs a plug with 2 black lines. That means using either headphones without a mic or getting a cheap converter plug. I hope this is helpful. :)

This product works good for my application which was simply connecting my mixer to my phone and going live to fb. The attenuation it provides helps alot with how the phone takes in the signal. Solved alot of time/problems with the volume being way to high and having to experiment over and over with volume checks like i did with other solutions i had found. Definitely a good alternative to the more expensive solutions i found along the way. I had received a faulty cable. Customer service was good and they did what they said they would do which was send a replacement and it arrived fast. The company stood by their product.

I purchased this item so I could record directly from my mixer to my iPhone using the built-in Voice Memos and Camera apps. Sometimes I don’t want to go through all the extra work and just want to record a quick “live” performance to send to friends and family, and this was the answer. Prior to this, I tried using a coiled TRRS adapter to feed the line out to the microphone channel on the iPhone, but I had to turn the mixer volume all the way down, and the recordings would suffer from quality issues and distortion. The iPhone microphone input is very sensitive, and my Peavey mixer preamps are on the high side. Using this adapter, I have been able to keep my mixer turned up and effortlessly record near studio-quality directly to my iPhone to make nifty little impromptu music videos and share songs I’m working on quickly with voice memos. It’s been about six months now and I am still very glad I bought this adapter. I only wish I had this years ago! The material and workmanship is of high quality, so I suspect this will last a very long time, but if I ever needed to buy another, I definitely wouldn’t hesitate!

Works as described. Sound sampled sound actually improved with the use of this.

This adapter did not work as advertised for me. I am a drummer and want to record videos with my iPhone 6s Plus, but with quality audio. I want to be able to run the "line-out" from my mixer to my iPhone, which is what this product claims can be done to achieve "crystal clear audio". I connected my mixer to the "line" input of this adapter and upon playback, confirmed that the adapter never disabled my iPhone's external mic as it is supposed to do when taking audio from another source. In fact, after several more experiments, I could confirm that the ONLY recorded audio source was still from my iPhone's external mic. I then thought maybe I was using the wrong input of the adapter and switched my mixer's output to the "headset" input of this adapter. This time my recordings were completely useless - saturated and choppy distortion. I am thinking this may be a compatibility issue that the manufacturer needs to research and in turn, change the product's description. For example, maybe this adapter is compatible only with certain cell phones, or operating systems?

This product has worked seamlessly for me. I absolutely love it! It's truly a great product that I highly recommend.

Podcasters, vloggers, and video content creators, this is a great tool for those of you who want to record with an external mixer and a tablet or iDevice.This product attenuates the incoming signal from the mixer to a crisp, line-level signal, that I record directly into my iPad, along with other signals run into my board, i.e. background/intro music, other mics for guests, etc.I bought a cheaper TRRS splitter that did not attenuate the input (mic) signal for a vlogging/live-streaming project. It required a very low output volume from the mixing board, resulting in a lot of background noise in the recording.This alleviated much of that issue, and greatly improved the clarity of my voice on videos.

Did exactly what it was supposed to do. Great product. Purchased it for audio backup over cell phone connection for church webcast. Voice was great, but music was choppy. Apparently this is typical for cell service, and not the fault of this adapter.
