As with many things, it is possible to make an invisible earphone set out of stuff you may have lying around the house and materials that are easy enough to source online. For an easy-to-follow instructional video below.

The method relayed here has been taken from Frank GuYun of Instructables.com. Links to the original article have been provided. In order to follow the process completely, you’ll need to follow both his technical schematics and his instructional video. This answer will work best if you relate to it as a companion piece, or ‘checklist’ if you will.

What now follows is a step-by-step guide to making your own pair of invisible earphones.

You will need:

1x Piece of cardboard (ideally larger than your head).

2x (or more) Neodymium magnets.

1x Knife.

50m Enamelled wire.

2x LM386 batteries.

1x Soldering iron.

1x Circuit board (and components, including headphone jack)

1x Multimeter

1x MP3 player

1x Roll of electrical tape

STEP ONE – You’ll need to acquire some small magnets (about 6mm in length and the same in diameter is best). If buying online, the best keywords to use are ‘neodymium + magnet’, as this will generate the type of magnet you will need.

STEP TWO – You will now need to make a coil necklace. For instructional reference photos of this process, click HERE. Firstly, you will need a piece of cardboard and roughly 50 metres of enamelled wire. Enamelled wire is copper wire that is coated with polyurethane. The wire necklace must be able to fit around your head. Fashion the wire ring into a necklace that fits you comfortably (and can easily be taken on or off). Then, you cover the wire with electrical tape (in order to protect it). Next, take a knife and carefully strip away the plastic tips of the wires (you’ll find out why later).

STEP THREE – You now need to source two LM386 batteries. These batteries will power the earphones. Then, you need to construct the amplifier; a schematic is linked HERE regarding what components are needed (and what goes where). The amplifier is relatively easy to construct, but requires patience and a little bit of electronics experience. Following the video is absolutely the best way to do this.

STEP FOUR – Connect the wires to the appropriate spots on the amplifier (remember when you stripped those wires? Well now you need to solder them into place). Locate the grand wire using a multimeter and attach everything to the circuit board the way that Frank does.

STEP FIVE – Place the wire necklace around your neck and the small magnet inside your ear. Then plug the device into your MP3 player and listen to some tunes!

Asked by Betty from Hammersmith

I take it you’re a newer reader and you therefore aren’t aware of my dislike for recommending specific sets of headphones. In a usual case, (like when one reader asked me to recommend sweat-proof headphones) I have to answer with “it depends on a multitude of factors, such as how often you use them, how important sound quality is to you or even (in that one case) how much you tend to sweat. However, I’m not going to let you down, Betty, because waterproof headphones are actually a bit different… Continue reading How do waterproof headphones work?

How to Clean your Surveillance Earpiece Tube

Again one more short article i found remarkable around the topic of radio accessory’s, what would you do if i didn’t post this ehh? you’d have to find the initial content, and the chances that you found it could be slim, so think yourself fortunate that i’ve shared this wonderful piece with you.

 

A surveillance earpiece is a listening device that transmits sound for hands-free communication. It is a good communication accessory for two-way communication that is mostly used in security operations and mobile phones. If you are working in industries like transportation, aviation, security, mining and other industries that has intensive security, earpiece tubes are important equipment to you.

Gupta: Cell phones, brain tumors and a wired earpiece

What would you do if i stated I had found a radio accessory short article that is not only fascinating but educational also? I knew you wouldn’t believe me, so here it is the informative, superb and appealing article

By Dr. Sanjay Gupta, Chief Medical Correspondent

Just about every time I use a cell phone, I plug in my wired earpiece first. Having discussed the use of earpieces on several news shows, people expect to see me using one. If I am walking around the CNN studios, my colleagues often comment on it. In airports, people will stop me in the rare cases I forget to use the earpiece, and remind me about it. Perhaps, they are intrigued because I am a neurosurgeon who openly shows some concern about cell phones. Continue reading Gupta: Cell phones, brain tumors and a wired earpiece

What earpieces work with police radios

There are quite a few police earpieces on the market right now, Renée, so the high likelihood is that whatever you need, someone, somewhere will be selling it. If it helps, I’ll give you a bit of an overview…

If you’re in the market for an overt earpiece, or even if you fancy something a bit more discreet (like, um, a covert earpiece), you’ll certainly be able to find it on the World Wide Web. Police organizations across the world employ a wide variety of communications equipment, from ‘listen only’ devices to PTT (Push To Talk) earpieces and, as I said, a significant portion of that equipment is available for consumer purchase.

Why isn’t there a Dick Tracy style radio wristwatch on the market? (Asked by Nadia from Los Angeles, California)

(Asked by Nadia from Los Angeles, California)

Before I answer your question, I have a question for you; what’s the weather like in the City of Angels?

Because right now, as I type this from my home in the UK, its bloody freezing and if it’s warmer where you are, then I think I may have to answer your question in person!

Just kidding.

On to your question, does it matter if the watch isn’t ‘Dick Tracy’ branded? Because if that’s what you’re after, then I’m sorry to say that, to the best of my knowledge at least, a ‘Dick Tracy’ branded two-way radio wristwatch doesn’t exist. If/when they make another DT movie (the last time they did, I was a little boy and I had the promotional T-shirt, so we must be due for one), then it seems likely that they will make one.

The Bluetooth headphone could have been about for years, but which one of these current crop is worth purchasing?

OK, To find the ‘flaking’ part of my answer out of the way nice and early, I’ve to mention that it is dependent completely on what you would like from the headphone. There is not much point spending out on an all-singing, all-dancing tremendous-headphones if all you need is a basic model, but, by the same token, great superiority doesn’t come cheap in the world of electronics.

Though, that is not what you planned to hear, is it? Continue reading The Bluetooth headphone could have been about for years, but which one of these current crop is worth purchasing?

How does bone conduction work?

Bone conduction headphones (commonly referred to as ‘Bonephones’) are actually really clever. In order to best explain how they work, I’ll need to take you on a journey into the Human ear…

No, not literally. That would be disgusting.

OK, so you know how sound travels through the air? Surely you must have done that science experiment at school where you hear sound disappearing into an airless vacuum? Yup, it’s just like that. Continue reading How does bone conduction work?

Will I be Able to Hear Bone Conduction Headphones Even if I Wear Earplugs?

Because bone conduction bypasses the ear entirely and directly stimulates the ossicles (which is the scientific name for the tiny bones that reside in your inner ear, as well as the rationale behind comic book hero Daredevil’s athletic prowess), it is entirely possible to stick your ear plugs in and still listen to your ‘Bonephones’.

 

In some respects, it’s actually preferable. Y’see Nick, using headphones is fine and dandy, until you have to turn the volume all the way up in order to drown out noisy children, busy traffic and/or people shouting into their phones all around you. After that, if you increase the volume to too great a degree, you can expose your ears to sounds that can actually permanently damage your hearing.

Kenwood 2-pin and kenwood multi pin connectors, what earpieces work on which 2 way radio?

The very best types are the two-pin connector and also the multi-pin connector. The 2 pin type features two connector pins along with the multi-pin model features multiple pins. Any variation in functionality is mostly a subject of customer discretion.

The 2-pin connector’s piece includes an in-line PTT (push-to-talk) key and a in-built mic. It also has a surveillance audio tube and comes complete with the apparel clip. This Kenwood radio earpiece is for just over £20 (excluding shipping and handling fees).

The multi-pin connected earpiece is a different type of connector completely. However, the earpiece is the same, since it also features an in-line PTT button, a in-built mic, surveillance tube and clothing clip. The price is a little bit more than the 2-pin variety.

Both types of Kenwood earpiece can be improved by spending more money and can include features like the ‘swivel’ earloop, for bigger ease of use and comfort, a noise-reduction characteristic with the steel clothing clip (replacing the synthetic version).

The types of connectors similar with Kenwood 2 way radios are imperfect in comparison with some other manufacturers, but Kenwood identify when to focus on a certain area, because at times less is more.

Kenwood radios may only link via two types of connector, but their gear is among one of the best in the world. A Kenwood walkie talkie consumer will not have to spend undue time searching his/her choices and researching them before purchase, provided the connector/earpiece falls into one of their two aforementioned categories, then the equipment works fine.

EarpieceOnline have been producing quality products since 2007 and they have a long history of trust, client devotion and cutting edge equipment. Because of this, Kenwood earpieces are popular and usually sell on the internet..

Why are there many connectors for Icom earpieces?

The four different Icom radio earpiece connectors connect the earpiece in question to four different types of two-way radio or, at least, four different types of connector.

Generally, it is good advice to make absolutely sure that your chosen earpiece can connect with the radio you intend to use. Not all radios use the same fittings, which is why there are so many different types of connector available.

A straight pin connector, for example, works best when used on marine radios, but is also compatible with Maxon and Vertex radios. Another thing to take into account is the activity that the earpiece is going to be used for. If the user is going to be standing still for prolonged periods of time, then he/she may require a different type to the one that may be preferable if the user is going to be engaging in strenuous exercise.

Two-way radios are used in a great many distinct environments, including shopping centers, building sites, roadway maintenance, fleet and transport operations, shipping, factory floor work, security, healthcare, private transport and much more besides. Because of this, there are many different types of earpiece connectors.

The four available Icom earpiece connectors indicate the jobs that the compatible two-way radios were likely designed for. This does not necessarily mean that an Icom radio would be unsuitable for other work, just that it is probably particularly suited to a certain type of job.

The different connectors also have distinct methods of working, even though their basic external operations are usually indistinguishable from one another. Icom have gone to great lengths to make their earpieces among the best in the world. One way they have done this is by allowing the earpiece connectors to be tailor made for specific tasks.
