I’ve always used headphones to listen to music, podcasts and audio books because all the earphone buds I tried in the past were *really* uncomfortable.
They’re passive noise-isolating upto 26 dB, blocking a lot of outside noise like buses, trains, city sounds etc by fitting snugly into your ear. Can be worn comfortably in hot, dry or humid Australian weather when wearing headphones would have made your ears feel hot and sweaty.
Are tiny themselves and fit in a small plastic case which can be slipped into your pocket or handbag. You’ll have to clean ear wax particles out of them regularly because these earphones are stuck inside your ear canal. A big advantage of in-ear headphones is the noise isolation they provide, an area in which the Ultimate Ears 700 in-ear headphones generally perform well. In the tutorial below you will learn how to frankenstein yourself some decent $30 Headphones that enable you to monitor sound on a noisy set with certainty – everything you hear will be the microphone feed … as if you were sitting in a quiet room. When you are on set, and the set happens to be on an otherwise busy street with cars rushing by and people talking in the background, you are in a difficult environment. The basic, underlying problem is: There will always be noise unless you are in a well-controlled interior environment. Is that air conditioning we can’t turn off actually being recorded by the lavalier, or do I just hear it through the headphones?
The two basic ingredients: Regular but decent headphones, and construction worker earmuffs. Solution 2 is for the stingy DIYers out there, like myself: Building headphones that are passive Noise-Canceling.
After your surgery, you should have the headphone cables connected to the two headphone speakers, and nothing else. Did you ever get caught somewhere on set with your headphone cable, and janked your half head off? As you can see on the picture, my headphone speakers were embedded in a small plastic platform with a few holes in it – the perfect place for cable ties.
The cable ties (here, already cut to length after tightened) hold the cable firmly to the frame of the headphone driver, which makes sure the sensitive wires at the driver base can't be damaged in case the cables get pulled with force. Put the driver into the ear muff's hollow space, and cover it with the felt pad that the headphones came with. The Construction Worker Earmuffs have quite a big amount of space between their inner foam insulation and the ear that will wear them – in that void space, we will place our headphone speakers.
Now you have to find a way to let the headphone speaker cables stay attached to not just the speakers, but also the earmuffs – otherwise, every time you yank on the cable, the speakers will pop out of their soft embedding in the muffs.
By just trying it on, you will see the amazing difference these tight-fitted, passive Noise-Canceling headphones have compared to “regular” headphones – nevertheless, that’s not a very scientific statement.
Hence, I made an objective test by inserting lavalier microphones between my ears and two pairs of headphones – the frankensteined pair, and an identical, unmodified pair. Willkommen auf U, S, and Toby!Dieser Blog handelt uber das Studium am Santa Monica College in Los Angeles (USA) und meinen Erfahrungen mit der Welt des Filmemachens in Amerika. Schnelle und kaputte Autos, 50.000$ schwere Studentenfilmprojekte und gigantische Sandpenisse sind hier an der Tagesordnung. The complete, illustrated filmography of Tobias Deml, an Austrian Cinematographer and Visual Artist. Unser neuester Film, "Chinatown Love Rectangle": Eine verzwickte Liebesgeschichte, bei der die Gefuhle von vier Menschen aufeinanderkrachen und von zwei Menschen ausgelebt werden. Being passive means they don’t need batteries which are required by all noise canceling headphones.


Ultimate Ears custom earphones are used by 75% of the world’s touring professional artists for live performances. Good quality headphones with noise cancelling or noise isolating features are usually quite bulky.
So in comparison the cost of buying Logitech Ultimate Ears 700 (AUS $200-$299) seems really high because earphones all look quite similar, the quality difference can only be heard by trying them on.
They provide up to 26dB of passive noise isolation from external sources, so you won’t have to turn up the volume excessively to hear the music over your surroundings. Handy in-flight attenuator saves you from Captain Blowhard’s eardrum-exploding announcements.
Cable noise will be distracting for joggers or anyone planning to use the headphones while exercising. One possible downside you missed is the risk of losing track of your surroundings when walking and listening to something – this was a bigger problem with the sennheisers than the Apple ones, the latter letting in more of the surrounding noise. When you’re on a documentary shoot in a noisy factory or a train, it will be hard to monitor your recorded audio properly. And that noise will penetrate your on-set headphones and make it difficult for you to distinguish if the noise actually comes from your microphone feed, or if it just bleeds through the plastic caps of your headphones.
Are the cars driving by part of my shotgun mic’s signal, or are my headphones just too thin?
These specialty headphones are equipped with small microphones on their outside shell that record the environment noise. Passive in the sense that instead of working with inverted waveforms, they try to get rid of the bleeding effect that thin, loosely fitted headphones bring with them. They will direct you to some strange-looking plastic ear muffs that sit really tightly and isolate you from the rest of the world, pretty much.
Carefully remove the leather-type donuts (the soft parts of your headphones) – we will recycle them later. I led the cable around the speaker and gave the cable-wire transition a few millimeters of slack.
Also, note that there is a gap between the foam flooring of the earmuffs and the leathery donuts that attach to your ear, which lets outside sound bleed through – we will take care of that. To solve that, use a knife or thin scissors to lift off the [glued-on] felt padding on the headphones’ outer shell, on each side. I used electrical tape, since I figured that drilling through the plastic shell would provide me with an attachment point but ruin the isolating effect of the shell itself.
The red electrical tapes cover a bit of gaff tape, which holds the cables to the outside body of the headphones - another safety net in case the cables get pulled on. I then played music from my external computer speakers, while listening to a distinctly different voice-over recording inside the headphones.
All you have to do is embracing the pressure of the earmuffs during a recording – no worries, millions of construction and factory workers around the globe have learned to like it, so you have good chances of learning it too.
This list of projects includes shorts, features, commercials, music videos and image films shot in the last 3 years, and credits as Cinematographer, Producer, or Director.
It's my first serious film, my first "big" production - an experimental short film that is partially running backwards, employs meaning between the lines and was shot on two December days in 2010. Etwa 30 Leute sind heute am Set, und einige unbekannte Faktoren mussen bewaltigt werden: Eine unerlaubte gefilmte Busfahrt, ein unerlaubter Dreh an einer Busstation mit komplexer Handlung, ein quer durch den Verkehr geworfener Fussball und eine 3-minutige 1-shot-Szene, bei der ein Mann gefeuert wird und zu weinen beginnt.
In practice, we found most external noise was isolated fairly well provided music was playing at a reasonable volume.
A small processor takes this audio signal, inverts the wave information (mirrors the waveform) and injects it into the headphones.


The basic idea for this concept stems from a few DIYers online from a couple of years ago; I decided to take their concept (which was developed for listening to music) to the on-location audio world and improve on it.
I can personally recommend the Sony MDR V150 headphones, which I bought a few years back for $20. If they have multiple ones and you have a choice, try all of them and buy the ones that have the best isolation-comfort ratio. Take a screwdriver, knife, saw, dwarf prybar or jackhammer – whichever tool you have handy – and open up the ear portions of your headphones.
You can plug in your headphones and play some music to find out which side gives off the clearest and loudest sound (usually the side that was mounted towards your ear initially).
Place this felt disk now on top of the speakers, while making sure that the cable leading to the speakers is taking a smart path into the earmuffs. I also recommend making a few marks (top, bottom, side) of “L” and “R”, so you know right away where left and right is – since the earmuffs don’t have a left or right side by default. By having the lavalier microphones where my ears are, I could analyze what I am actually hearing. We were about 25-30 people that were working on the film, had permits for some things, and totally no permits for other, dangerous parts of the film. So viele Unbekannten fur ein Team von Studenten, die nur ein paar Filme am Buckel haben - das bedeutet: You gotta step your game up. Am Anfang des Filmes steht eine Verfolgungsjagd durch einen chinesischen Markt, dann werden Streit und Liebeskummer vereint. Dre sound profile delivers pure audio integrity for crystal clear highs, signature bass and sonically true mids. Excessive noise sources, like trains, could still be heard but nearby conversation and other natural sounds were blocked out. The result: The two perfectly symmetric waveforms that result from the outside noise cancel each other out, and what remains is the microphone feed.
The better they insulate, the tighter they usually sit on the head – and you have to decide between quality isolation and wearing comfort.
They usually have two screws holding the shells together, and then a few snap-on plastic pieces. While the cable itself is pretty sturdy, the tiny wires that connect it to the speaker are not.
If you want to do a stress test, grab the cable by the throat and swing the speakers through the air.
Once done, grab yourself the leather-like donuts you removed initially, and squeeze them in between the felt padding and the much thicker donuts of the earmuffs.
Initially, they will hurt, but you can get accustomed to the constant pressure with little practice.
Be careful to not damage the interior during your surgery, as well as the felt topping on the shell. I personally recommend to buy thin cable ties as well, those should be part of your DIY cave already though. Also, be careful not to damage the cable and its wire connections to the headphone speakers. In the case of my Sony headphones, I had to use strong scissors to cut the shell where it enclosed the headphone cables – and had to be careful not to pull on the cable, since it is connected to the headphone speaker with two hair-thin wires that looked like they would love to rip.
