How Many Balanced Headphone Connections Do Audiophiles Need?
A phone connector , also known as phone jack , audio jack , headphone jack or jack plug , is a family of electrical connectors typically used for analog audio signals.
The standard is that a plug described as the male connector will connect with a jack described as female. The phone connector was invented for use in telephone switchboards in the 19th century and is still widely used. The phone connector is cylindrical in shape, with a grooved tip to retain it. In its original audio configuration, it typically has two, three, four or, occasionally, five contacts.
Three-contact versions are known as TRS connectors , where T stands for "tip" , R stands for "ring" and S stands for "sleeve". Ring contacts are typically the same diameter as the sleeve, the long shank.
The outside diameter of the "sleeve" conductor is 6. The "mini" connector has a diameter of 3. The "mini" connector has a length of 14 millimetres 0. Specific models, and connectors used in specific applications, may be termed e.
The 3. In the UK, the terms jack plug and jack socket are commonly used for the respective male and female phone connectors. Phone plugs and jacks are not to be confused with the similar terms phono plug and phono jack or in the UK, phono socket which refer to RCA connectors common in consumer hi-fi and audiovisual equipment. Modern phone connectors are available in three standard sizes.
In February , C. Scribner was issued US Patent , [14] for a "jack-knife" connector that is the origin of calling the receptacle a "jack". Patents ,, [16] ,, [17] and , relating to an improved design that more closely resembles the modern plug. Clausen received a patent on an improved design. Western Electric was the manufacturing arm of the Bell System , and thus originated or refined most of the engineering designs, including the telephone jacks and plugs which were later adopted by other industries, including the U.
By , Western Electric had designed a number of models for different purposes, including: [20]. The three-conductor version became very popular with its application on the Walkman in , as unlike earlier transistor radios, these devices had no speaker of their own; the usual way to listen to them was to plug in headphones.
There is also an EIA standard for 0. The 2. They often appeared next to a 3. They were also used for low-voltage DC power input from wall adapters. In the latter role they were soon replaced by coaxial DC power connectors. Four-conductor versions of the 3.
A four-conductor version is often used in compact camcorders and portable media players, providing stereo sound and composite analog video. By the s, broadcast radio stations were using Western Electric Code No. The type plug was used instead of the standard type switchboard plug because the location of the large bulb shape on this TRS plug would have resulted in both audio signal connections being shorted together for a brief moment while the plug is being inserted and removed.
The Type plug avoids this by having a shorter tip. Professional audio and the telecommunication industry use a 0. In addition to a slightly smaller diameter, they have a slightly different geometry. Though unable to handle as much power, and less reliable than a 6.
These connectors are still used today in telephone company central offices on "DSX" patch panels for DS1 circuits. A similar type of 3. Plugging a stereo plug into one of the two mono jacks typically results in the audio coming into only one ear. Adapters are available. A short-barrelled version of the phone plug was used for 20th century high-impedance mono headphones, and in particular those used in World War II aircraft. These have become rare.
It is physically possible to use a normal plug in a short socket, but a short plug will neither lock into a normal socket nor complete the tip circuit. Less commonly used sizes, both diameters and lengths, are also available from some manufacturers, and are used when it is desired to restrict the availability of matching connectors, such as 0. US military phone connectors include both 0. Commercial and general aviation GA civil airplane headset plugs are similar, but not identical.
In the microphone plug the Ring is used for the microphone hot and the sleeve is ground. The extra tip connection in the microphone plug is often left unconnected but is also sometimes used for various functions, most commonly an optional push-to-talk switch, but on some aircraft it carries headphone audio and on others a DC supply. The original application for the 6. Of these many varieties, only the two-conductor version with a rounded tip profile was compatible between different manufacturers, and this was the design that was at first adopted for use with microphones , electric guitars, headphones , loudspeakers , and other audio equipment.
When a three-conductor version of the 6. This attempt has long been abandoned, and now the convention is that all plugs fit all sockets of the same size, regardless of whether they are balanced or unbalanced, mono or stereo. Most 6. The profiles of stereo miniature and sub-miniature plugs have always been identical to the mono plugs of the same size. Because of a lack of standardization in the past regarding the dimensions length given to the ring conductor and the insulating portions on either side of it in 6.
This can result in a contact in the socket bridging shorting the ring and sleeve contacts on a phone connector. In the most common arrangement, consistent with the original intention of the design, the male plug is connected to a cable, and the female socket is mounted in a piece of equipment.
Personal computer sound cards , such as Creative Labs ' Sound Blaster line, use a 3. Sometimes termed phantom power , this is not a suitable power source for microphones designed for true phantom power and is better termed bias voltage. Note that this is not a polarizing voltage for the condenser, as electrets by definition have an intrinsic voltage; it is power for a FET preamplifier built into the microphone. Compatibility between different manufacturers is unreliable.
The Apple PlainTalk microphone jack used on some older Macintosh systems is designed to accept an extended 3. If a PlainTalk-compatible microphone is not available, the jack can accept a line-level sound input, though it cannot accept a standard microphone without a preamp.
Normally, 3. Thus, for a sound card with 5. This is to accommodate rear-center 6. Note that Creative's documentation uses the word "pole" instead of "conductor". Some portable computers have a combined 3. Support for input was dropped on various later models [39] [40]. Some newer computers, such as Lenovo laptops, have 3.
These are particularly used for voice over IP. Two incompatible variants exist, of 15 millimetres 0. Attempting to fully insert the longer 17 mm plug into a receptacle designed for the shorter 15 mm plug may damage the receptacle, and may damage any electronics located immediately behind the receptacle. The shorter 15 mm TRRS variant is more common and fully physically compatible with 'standard' 3.
Many small video cameras, laptops, recorders and other consumer devices use a 3. These fall into three categories:. Plug-in power is supplied on the same line as the audio signal, using an RC filter. If a recorder provides plug-in power, and the microphone does not need it, everything will usually work ok.
In the converse case recorder provides no power; microphone needs power , no sound will be recorded. Neither misconfiguration will damage consumer hardware, but providing power when none is needed could destroy a broadcast-type microphone. These are used both for handsfree headsets esp. Wireless connectorless headsets or headphones usually use the Bluetooth protocol. Some computers now also include a TRRS headset socket, compatible with headsets intended for smartphones.
The four conductors of a TRRS connector are assigned to different purposes by different manufacturers. Any 3. Mono audio will usually work, but stereo audio or microphone may not work, depending on wiring. Two different forms are frequently found, both of which place left audio on the tip and right audio on the first ring for compatibility with stereo connectors.
Where they differ is in the placement of the microphone and return contacts:. The first, which places the ground return on the sleeve and the microphone on the second ring, is standardized in OMTP [41] and has been accepted as a national Chinese standard YDT — It is mostly used on older devices, such as older Nokia mobiles, older Samsung smartphones, and some Sony Ericsson phones, [42] and products meant for the Chinese market.
The second, which reverses these contacts, with the microphone on the sleeve, is used by Apple 's iPhone line, and has become the de facto TRRS standard, to maintain compatibility with these products. Headsets using this wiring may be indicated by white plastic separators between the rings. If a CTIA headset is connected to a mobile phone with OMTP interface, the missing ground will effectively connect speakers in out-of-phase series, resulting in no voice on typical popular music recordings where the singers are in the center; in this case, if the main microphone button is held down, shorting across the microphone and restoring ground, the correct sound may be audible.
The 4-pole 3. Some devices transparently handle many jack standards, [61] [62] and there are hardware implementations of this available as components. Some devices apply voltage to the sleeve and second ring to detect the wiring, and switch the last two conductors to allow a device made to one standard to be used with a headset made to the other. MMIC , outlines technical requirements and test methods for a 5-pole socket and plug configuration. Therefore, P. TRRRS connectors enable following audio applications: active noise cancelling, binaural recording and others, where dual analogue microphone lines can be directly connected to a host device.
Panel-mounting jacks are often provided with switch contacts.

Just by looking at the plug of an analog headphone cable, we can determine many of its properties , such as whether it supports a microphone, whether it supports stereo signals, and whether it supports balanced connections. The all-digital Lightning connector is capable of transferring more data than an analog 3. Instead, this article will focus on the differences between the many types of analog headphone plugs. All plugs have several conductors , which serve as contact points between the plug and the jack.

Single Ended vs. Balanced Connections is a hot topic of discussion these days. Many people believe balanced means better, but this is not necessarily true. Just because a headphone amp is balanced does not mean that another headphone amplifier that is single ended can't sound better. In order to explain the benefits of both types of amplifier connections, we will start with a bit of hi-fi audio history. Balanced on the amplifier side is called "differential signaling. This method was very popular with car audio. You can still do this occasionally today but not as often.
Balanced Vs Unbalanced Headphones (Differences, Which To Buy)
Have you ever worn your headphones and noticed that one side is louder than the other? Typically, in this situation, we try to adjust the audio jack by twisting it around or unplugging it. But this does not always work. And it can really be frustrating, especially since one side is delivering clear, seamless audio, whereas the other side offers muffled sound.
