There are many of us out here who only trust cables for connectivity. People can go around with their wireless devices all they like, but we don’t want to have to make sure to charge everything before using it. We just want to start using the device!
Fortunately, cables are not going anywhere. They are mostly required for audio video purposes which is something we need for both entertainment and work.
Primarily, there are two types of these connectors, one type passes a digital signal and the other type passes analog signal. The most popular analog audio connectors are the 2.5mm and 3.5mm connectors.
If we take a trip down memory lane, Sony’s iconic Walkman chose the 3.5mm port back in 1979. This made it famous. And when the technology industry evolved and/or copied the Walkman, everyone put this port on their devices. 20 years after the Walkman, the audio cable and the portable audio industry had become so iconic that Apple used its silhouette for their famous iPod ads.
With this cable, you never have to worry about running out of battery or its large size. All you have to take care of is that they don’t tangle.
The Uses of 2.5mm & 3.5mm Cables for Entertainment:
To carry a stereo signal you need two audio channels. The tip carries the left channel, the ring carries the right channel, and the sleeve is the ground channel. This is specific to the 3.5mm cable. And the 2.5mm cable can be used in phones that need to use headsets, or in smaller phone instruments that were cordless but needed a headset.
The most common use of a 2.5mm connector is for connecting a microphone to devices. When you need to have a separate microphone input and audio output an audio splitter is useful. This splitter is a 2.5mm to 3.5mm cable where the connector is 3.5mm and the other side has two 2.5mm female ports. These can connect a microphone and headphones, or two headphones. This cable comes in handy in case you want an external microphone input on your phone, and/or when you want to use headphones for the audio experience.
While buying audio video cables, you can check for whether it is mono sound or stereo sound, and if it has a microphone built-in. The mono channel connector will only have one ring, a sleeve, and the tip. If you are looking for a stereo sound experience, then the connector should have two rings. The tip carries the left signal, the first ring carries the right stereo channel, the sleeve is ground and the second ring is the microphone. It is in the TRS or TRRS connector format.
The 3.5mm connector can route analog dual channel audio for a device that uses the RCA audio video cable for video input and audio output. While this cable is old, it is most often used in gaming setups, that have a console hooked up to a TV, and more than one controllers attached to the console itself, along with headsets or stereo speakers.
Another use case is when you want to use an aux cable but your car’s music system is older. This requires you to use a 2.5mm to 3.5mm cable to connect your phone or mp3 player to it. An older system will also not have Bluetooth, so this cable is your best option for car entertainment.
That was entertainment; now let’s move on to work requirements.
The Uses of 2.5mm & 3.5mm Cables for Office Work:
If your line of work requires you to be talking on the phone for the better part of your day, you wouldn’t want to be constantly holding a phone. Generally, you are required to use a work phone, which is a corded landline phone. In this case, there are headsets that plug into the 2.5mm female port on the phone itself. You may not have a headset that has a 2.5mm connectors but have the more popular and reliable 3.5mm connector. In this case, you can simply use a male to female 2.5mm to 3.5mm cable. This way you can plug in your existing headset to your landline phone.
Concluding Note:
The audio video cables are in huge demand in the accessory market. There are plenty of accessory makers who make sure to put in ports that they think can provide with faster and smoother experience than Bluetooth or Wireless technologies.
The cable industry is going strong. Especially the audio-video cables as the sheer number of accessories we want to connect keep increasing every day. Read more: The Reason We Are Still Talking About Audio Video Cables in 2019
