    I think I get the basic concept.

    Plug the correct cables in, press the small lever down inside the cassette compartment to trick the deck into thinking there’s a recordable tape there, then press play and record. Correct?

    My actual question pertains to the cabling.
    Most of my BBX’s have a L and R microphone input. What are the correct plugs that go into the BBX? Are they 2.5? How many plastic rings are on the plug tips? Can anyone post pics of the cables they use or provide Amazon links?

    I have an iPhone 7 Plus that I use as a music source (lighting connector), and an iPhone 15 Pro Max with a USB-C. Are there cables such as these that will work with BBX mic inputs? If not, what is the plug on the source end? Just a 3.5 mini headphone jack?

    Hoping to use “mic in” and an iPhone or other source to play music on my BBX’s. I have a small FM transmitter with BT…overall works ok but volume is a lot lower than direct AUX IN.

    Thanks in advance for the info!

    I have a Google Pixel 6A
    I just got this Saturday

    My headphones plug into this and then while the headphones are plugged in you can also plug it into power and recharge your phone if necessary. This is a USBC.
    2. The microphone remote control is 2.5 mm the microphone. Jack is 3.5 mm and is mono when you have left and right. So it's only two pins with one plastic bit in between if you understand that.
    3. One of my microphone choices is this realistic which takes One battery which is electric condenser microphone that you can read, it does not have a 2.5 mm remote control. Jack, it just has the dual mono 3.5 mm jacks. Of course it has a dual head and you may have seen it in some of my old videos.
    To make it work, I have made a custom dual input mono to a stereo. Jack, so I can plug it into a device that only uses one stereo microphone input. Jack or I can plug it into a boombox via the two mono jacks. My choice. Here's a picture to illustrate

    Lastly, it's nice to have a double-ended 3.5 mm stereo cord here

    I have zillions of these y adapters from a 3.5 mm stereo Jack to a dual phono Jack

    So with all these options, there is many different ways to get your sound from your phone to your portable unit cassette playing item. Oh yeah!

    One more thing, here's a item that you might want to get from somewhere
    To play in your vehicle or to simply play in your working cassette deck via your phone via Bluetooth which I can't stand, but I have one for illustration purposes only. I don't normally use this device but I have one actually. I have a few.

    What? You don't have a cassette player in your vehicle or a CD player or?

    I've never done it with the MIC in but I remember in the 80's my buddy used to play guitar through a reciever by going through the headphone jack, they were both 1/4." I believe most Microphones are mono, I just looked at one of my nicer AIWA Mics and it has one ring by the tip. I have stereo microphones, usually used with Walkman sized units that have special tips with lots of rings.

    It would help to know the boombox some of the 70's units had different sized jacks.

    I'm with C2G, I also have the ION and another that has a slot for SD storage, they both need the tape deck on which always generates interference or hum and the volume is always low.

    Personally I use a Wicked Audio Reach, daily, hooked up to a boombox with AUX. They are no longer on their website but they're still cheap on Ebay.

    Wicked audio reach was not on my radar. I’ll pick one up. Thanks.

    Also thanks to C2G…lots of great info there too!

    The Wicked Audio Reach does not have headphone cords so make sure you also get a 3.5mm to R + L RCA jacks so you can plug it into your AUX in.

    Reli, did the manufacturer's expect people to use the inputs that way or is it a "glitch." Was it in any of the Owner's Manuals?

    They expected that you would use the mics to record a live performance, or that you'd want to do karaoke with a radio station. The JDM-market boxes even had wireless mics for that purpose.

    Mic inputs are typically designed to take a much lower signal level than a line input. If using a source like a phone you might get away with setting it to a low volume. If not attenuators are available e.g.
    https://www.ebay.co.uk/itm/375499733187
    You could make your own using a few resistors
    https://www.electronics-tutorials.ws/attenuators/attenuator.html
    but that is such a good price it might not be worth bothering.

    As for the having to press play to use the input on some boxes it is because they lack a dedicated switch setting for the inputs. To turn on the amplifier you have to either select the radio or press play on the cassette deck. Including one would have added about $1 to the price and probably never have been used by 90% of buyers.

    I was in the other 10%. The main reason for selecting a Sony CFS45L as my first boombox back in 1980 was that it has a specific Line-In switch position. That got used a lot as buying a cassette deck for my HiFi was very low on my list of spending priorities back then (and they weren't the sort of thing you would find in a thrift store). When I got my first CD player I was away from home so used the Sony to listen to it. The CD player output was too high for the Sony's DIN audio input leading to lots of distortion so I had to make an attenuator using six resistors.

    p.s. Going off topic by 1989 I recall going into a thift store and they had a stack of Hi Fi units like Amplifiers Tuners and Cassette decks.

    "Black HiFi separates £20 each. Silver £10 each"

    Black meant the HiFi was from the 1980s while silver was more likely to be 1970s and therefore less desirable. What you wouldn't find was any CD players. I thought the one I bought from a colleague was a bargain at £60 used. If you were lucky you might find some CDs. I bought quite a few used CDs at the bargain price of £7 each. Now CDs are three for £1 in charity shops.

    I have interpreted the question in other version - Jam_On_It wants to play a AUX - device ( May be Cinch, DIN or Headphone Jack ) over the MIC - Inputs of his Boom Box. Aren`t there casualities in Sound, because the MIC - Inputs have another electrical values as AUX ( Cinch ), DIN or Headphone - Outputs ? I for myself theretimes soldered a adapter from Headphone-Output ( 3,5 mm Stereo with 2 Rings ) to DIN Stereo ( 5 pins ) and it still works fine with my Sharp MD - Recorder and a GDR SV 3000 Amp.
    And i uses Stereo - Cinch - to - 3,5 mm - jack - Adapters ( Audio IN or OUT ).
    But i never used an AUX Output with a MIC - Input. Thats why you have different sockets for Input or Output in the Boxes.
