Reasons to buy

   1. Increased resolution and dynamic range: A new 30.4MP full-frame CMOS sensor not only offers a jump in resolution over its predecessor, but also improved Raw dynamic range.
    2. Dual Pixel AF: Continuous AF for stills is offered in Live View for the first time on a Canon full-frame camera, and it's extremely capable. Offering 80% frame coverage, it can detect faces and track them, even during bursts. And since on-sensor AF is inherently accurate, there's no need for calibration, even with fast lenses.
    3. New AF system: For viewfinder shooting, the 61-point (41 cross-type) AF module offers up to 24% greater vertical coverage over the Mark III. The center point is sensitive to -3 EV.
    4. 4K video: The 5D Mark IV can capture 4K (24/30p) video with continuous and decisive refocusing ? even on moving subjects ? thanks to Dual Pixel AF. Meanwhile, 4K Frame Grab means you can effectively shoot 8.8MP stills at 30 fps to grab the decisive moment.
    5. Touchscreen: The 5D Mark IV features a 1.62M-dot 3.2" full-time touchscreen that is a pleasure to use in Live View. Simply tap the screen to focus on or track a subject.

Things to consider


    1. Limited customization: While the Mark IV offers quite a few customizable buttons, the set of assignable functions per-button is frustratingly limited. This can make it difficult to set up exactly to your liking.
    2. Subject tracking: Despite a 150k-pixel RGB metering sensor for subject identification and tracking, the camera's ability to automatically shift AF points to stick to your subject is very situation-dependent and doesn't work reliably enough to depend on across a variety of scenarios.
   3.4K video limitations: There's a 1.64x crop factor for all 4K video, and the high bitrate Motion JPEG codec means you'll need large, expensive CF cards to record 4K.
    4. Video tools: Serious videographers will miss features like exposure peaking, zebras, and Log gamma profiles.

Do you know that amazon earbuds is topping the chart as bestseller in electronics at amzon? 
You might or you might not. But the big question is, what is so special about this earbuds that made it to be the no 1 bestseller in electronics at amazon today? That is what we need to find out.

First and foremost, do you know what is earbuds,? Earbuds can either be refer to cottonbuds or headphone. But in our article today we are going to be discussing about headphones.

Headphones  are a pair of small listening devices that are designed to be worn on or around the head over a user's ears. They are electroacoustic transducers, which convert an electrical signal to a corresponding sound in the user's ear. Headphones are designed to allow a single user to listen to an audio source privately, in contrast to a loudspeaker, which emits sound into the open air, for anyone nearby to hear. Headphones are also known as earspeakers, earphones or, colloquially, cans.

Circumauraland supra-aural headphones use a band over the top of the head to hold the speakers in place. The other type, known as earbuds or earphones consist of individual units that plug into the user's ear canal. In the context of telecommunication, a headset is a combination of headphone and microphone. Headphones either connect directly to a signal source such as an audio amplifier, radio, CD player, portable media player, mobilephone, video game consoles, electronic musical instrument, or use wireless technology such as bluetooth or FM radio.

  Brandes radioheadphones, circa 1920.




  Headphonesoriginated from the earpiece, and were the only way to listen to electrical audiosignals before amplifiers were developed. The first truly successful set was developed in 1910 by Nathaniel Baldwin, who made them by hand in his kitchen and sold them to the United States Navy.



  Somevery sensitive headphones, such as those manufactured by Brandes around 1919, were commonly used for early radio work. These early headphones used moving iron drivers, with either single ended or balanced armatures. The requirement for high sensitivity meant that no damping was used, thus the sound quality was crude. These early models lacked padding, and often produced excessive clamping forces on the wearer's head. Their impedance varied; headphones used in telegraph and telephone work had an impedance of 75 ohms. Those used with earlywireless radio had to be more sensitive and were made with more turns of finer wire. Impedance of 1000 to 2000 ohms was common, which suited both crystal sets and triode receivers.

 

   In early powered radios, the headphone was part of the vacuum tube's plate circuitand carried dangerous voltages. It was normally connected directly to the positive high voltage battery terminal, and the other battery terminal was securely grounded. The use of bare electrical connections meant that users could be shocked if they touched the bare headphone connections while adjusting an uncomfortable headset.



  In1943, John C. Koss, an audiophile and jazz musician from Milwaukee, producedthe first stereo headphones. Previously, headphones were used only by telephone and radio operators, and individuals in similar industries.

 

  The3.5 mm radio and phone connector, which is the most commonly used in portable application today, has been used at least since the Sony EFM-117J radio which was released in 1964.It became very popular with its application on the Walkman in 1979.

 Headphonesmay be used with stationary CD and DVD players, home theater, personalcomputers, or portable devices (e.g., digital audio player/mp3 player, mobilephone). Cordless headphones are not connected to their source by a cable. Instead, they receive a radio or infrared signal encoded using a radio or infrared transmission link, such as FM, Bluetooth or Wi-Fi. These are powered receiver systems, of which the headphone is only a component. Cordlessheadphones are used with events such as a Silent disco or Silent Gig.




  In the professional audio sector, headphones are used in live situations by disc jockeys with a DJ mixer, and sound engineers for monitoring signal sources. In radio studios, DJs use a pair of headphones when talking to the microphone while the speakers are turned off to eliminate acoustic feedback while monitoring their own voice. In studio recordings, musicians and singers use headphones to play or sing along to a backing track or band. In military applications, audio signals of many varieties are monitored using headphones.



 Wiredheadphones are attached to an audio source by a cable. The most common connectors are 6.35 mm (¼″) and 3.5 mm phone connectors. The larger 6.35 mm connector is more common on fixed location home or professional equipment. The 3.5 mm connector remains the most widely used connector for portable application today. Adapters are available for converting between 6.35 mm and 3.5 mm devices.







 Electrical characteristics of dynamic loudspeakers may be readily applied to headphones, because most headphones are small dynamic loudspeakers.

Headphonesare available with low or high impedance (typically measured at 1 kHz). Low-impedance headphones are in the range 16 to 32 ohms and high-impedance headphones are about 100-600 ohms. As the impedance of a pair of headphones increases, more voltage (at a given current) is required to drive it, and the loudness of the headphones for a given voltage decreases. In recent years, impedance of newer headphones has generally decreased to accommodate lowervoltages available on battery powered CMOS-based portable electronics. This has resulted in headphones that can be more efficiently driven by battery powered electronics. Consequently, newer amplifiers are based on designs with relatively low output impedance.



 The impedance of headphones is of concern because of the output limitations of amplifiers. A modern pair of headphones is driven by an amplifier, with lower impedance headphones presenting a larger load. Amplifiers are not ideal; they also have some output impedance that limits the amount of power they can provide. In order to ensure an even frequency response, adequate damping factor, and undistorted sound, an amplifier should have an output impedance less than 1/8 that of the headphones it is driving (and ideally, as low as possible). If output impedance is large compared to the impedance of the headphones, significantly higher distortion will be present.Therefore, lower impedance headphones will tend to be louder and more efficient, but will also demand a more capable amplifier. Higher impedance headphones will be more tolerant of amplifier limitations, but will produce less volume for a given output level.



  Historically,many headphones had relatively high impedance, often over 500 ohms in order tooperate well with high impedance tube amplifiers. In contrast, modern transistor amplifiers can have very low output impedance, enabling lower impedance headphones. Unfortunately, this means that older audio amplifiers or stereos often produce poor quality output on some modern, low impedance headphones. In this case, an external headphone amplifier may be beneficial.

 Sensitivity is a measure of how effectively an earpiece converts an incoming electricalsignal into an audible sound. It thus indicates how loud the headphones will be for a given electrical drive level. It can be measured in decibels of sound pressure level per milliwatt (dB (SPL)/mW) or decibels of sound pressure level per volt (dB (SPL) / V). Unfortunately, both definitions are widely used, often interchangeably. As the output voltage (but not power) of a headphone amplifier is essentially constant for most common headphones, dB/mW is often more useful if converted into dB/V using Ohm's Law:






 Alternatively, online calculators can be used.Once the sensitivity per volt is known, the maximum volume for a pair of headphones can be easily calculated from the maximum amplifier output voltage. For example, for a headphone with asensitivity of 100 dB (SPL)/V, an amplifier with an output of 1root-mean-square (RMS) voltage will produce a maximum volume of 100 dB.



 Pairinghigh sensitivity headphones with power amplifiers can produce dangerously highvolumes and damage headphones. The maximum sound pressure level is a matter of preference, with some sources recommending no higher than 110 to 120 dB. In contrast, the American Occupational Safety and Health Administration recommends an average SPL of no more than 85 dB(A) to avoid long-term hearing loss, while the European Union standard EN 50332-1:2013 recommends that volumes above 85 dB(A) include a warning, with an absolute maximum volume (defined using 40–4000 Hz noise) of no more than 100 dB to avoid accidental hearing damage. Using this standard, headphones with sensitivities of 90, 100 and 110 dB (SPL)/V should be driven by an amplifier capable of no more than 3.162, 1.0 and 0.3162 RMS volts at maximum volume setting, respectively to reduce the risk of hearing damage.

 Headphone size can affect the balance between fidelity and portability. Generally, headphone form factors can be divided into four separate categories: circumaural (over-ear), supra-aural (on-ear), earbud and in-ear.







  Circumauralheadphones (sometimes called full size headphones) have circular or ellipsoidearpads that encompass the ears. Because these headphones completely surround the ear, circumaural headphones can be designed to fully seal against the head to attenuate external noise. Because of their size, circumaural headphones can be heavy and there are some sets that weigh over 500 grams (1 lb). Ergonomicheadband and earpad design is required to reduce discomfort resulting fromweight. These are commonly used by drummers in recording.






  Supra-auralheadphones have pads that press against the ears, rather than around them. They were commonly bundled with personal stereos during the 1980s. This type of headphone generally tends to be smaller and lighter than circumaural headphones, resulting in less attenuation of outside noise. Supra-aural headphones can also lead to discomfort due to the pressure on the ear as compared to circumaural headphones that sit around the ear. Comfort may vary due to the earcup material.




  Both circumaural and supra-aural headphones can be further differentiated by  
t 

The type of earcups:

Open-backheadphones have the back of the earcups open. This leaks more sound out of the headphone and also lets more ambient sounds into the headphone, but gives a more natural or speaker-like sound and more spacious "soundstage"[further explanation needed] - the perception of distance from the source.



  Closed-back(or sealed) styles have the back of the earcups closed. They usually block some of the ambient noise, but have a smaller soundstage, giving the wearer a perception that the sound is coming from within their hea






  Semi-openheadphones, have a design that can be considered as a compromise between open-back headphones and closed-back headphones. This may imply that the result combines all the positive properties of both designs. Some[who?] believe the term "semi-open" is purely there for marketing purposes. There is noexact definition for the term semi-open headphone. Where the open-back approach has hardly any measure to block sound at the outer side of the diaphragm and the closed-back approach really has a closed chamber at the outer side of the diaphragm, a semi-open headphone can have a chamber to partially block sound while letting some sound through via openings or vents.





   Earphones


  Earphones (popularly called "earbuds" in recent years) are very small headphones that are fitted directly in the outer ear, facing but not inserted in the ear canal. Earphones are portable and convenient, but many people consider them to be uncomfortable.They provide hardly any acoustic isolation and leave room for ambient noise to seep in; users may turn up the volume dangerously high to compensate, at the risk of causing hearing loss. On the other hand, they let the user be better aware of their surroundings. Since the early days of the transistor radio, earphones have commonly been bundled withpersonal music devices. They are sold at times with foam pads for comfort.





  In-ear monitors extend into the ear canal, providing isolation from outside noise.



  In-earheadphones, also known as in-ear monitors (IEMs) or canalphones, are smallheadphones with similar portability to earbuds that are inserted in the earcanal itself. IEMs are higher-quality in-ear headphones and are used by audio engineers and musicians as well as audiophiles.



  Because in-ear headphones engage the ear canal, they can be prone to sliding out, and they block out much environmental noise. Lack of sound from the environment can be a problem when sound is a necessary cue for safety or other reasons, as when walking, driving, or riding near or in vehicular traffic.



  Generic or custom-fitting ear canal plugs are made from silicone rubber, elastomer, or foam. Custom in-ear headphones use castings of the ear canal to createcustom-molded plugs that provide added comfort and noise isolation

 A headset is a headphone combined with a microphone. Headsets provide the equivalent functionality of a telephone handset with hands-free operation. Among applications for headsets, besides telephone use, are aviation, theatre or television studio intercom systems, and console or PC gaming. Headsets are made with either a single-earpiece (mono) or a double-earpiece (mono to both ears or stereo). The microphone arm of headsets is either an external microphone type where the microphone is held in front of the user's mouth, or a voicetube type where the microphone is housed in the earpiece and speech reaches it by means of a hollow tube.







  Telephone headsets connect to a fixed-line telephone system. A telephone headset functions by replacing the handset of a telephone. Headsets for standard corded telephones are fitted with a standard 4P4C commonly called an RJ-9 connector. Headsets are also available with 2.5 mm jack sockets for many DECT phones and other applications. Cordless bluetooth headsets are available, and often used with mobile telephones. Headsets are widely used for telephone-intensive jobs, in particular by call centre workers. They are also used by anyone wishing to hold telephone conversations with both hands free.



  For older models of telephones, the headset microphone impedance is different from that of the original handset, requiring a telephone amplifier for the telephone headset. A telephone amplifier provides basic pin-alignment similar to a telephone headset adaptor, but it also offers sound amplification for the microphone as well as the loudspeakers. Most models of telephone amplifiers offer volume control for loudspeaker as well as microphone, mute function and switching between headset and handset. Telephone amplifiers are powered by batteries or AC adaptors.


  In late 2016, some new stereo cordless headset are coming on the market. There are no wire between the 2 headsets and no wire between the headset and the smartphone or PC.
