Portable Tesla Hi-Fi headset with Apple-certified smartphone remote and mic, closed

Compact Tesla sound

Like its sibling T 51 p, the focus for design of the T 51 i is delivering unrivalled sound quality. With new and improved drivers the headphones deliver in an inspiring way – right from the first moment. A particularly deep bass response and transparent, clear highs are apparent from the T 51 i due to the common properties that make all Tesla headphones so special: high efficiency and low distortion. The result: a clear, powerful sound across the entire frequency range, even at low levels. The closed design of the T 51 p also isolates external noise very effectively.
Further information about Tesla Technology Completely re-engineered transducers (drivers) based on a neodymium ring magnet with optimized magnetic field characteristics. This combination creates a magnetic field inside the transducer which is far stronger (> 1,2 Tesla - measuring unit for magnetic flux density - with current headphones the strength of the magnetic field is < 0,65 Tesla) than in standard headphones. Because of this increased magnetic field, the voice coil is more compact but still provides a very high degree of efficiency. The membrane, consisting of a 3 layer "compound foil", delivers an extremely precise frequency response and guarantees, in collaboration with the strong magnet, a transparent and distortion free sound..

Works on your iPhone and other mobile devices

Being an officially licenced product, you can be sure, that the T 51 i works smoothly on your iPod, iPhone or iPad. With the three-button remote and mic, you can use your T 51 i to control calls and media playback. All functions (except the volume up and down) work on other current smartphones and tablet computers as well, including Windows and Android devices.

High quality and elegant looks

The shiny beyerdynamic logo on the housing caps stands in sharp contrast with the brushed metal surfaces of the ear-cups. The cable has also been improved to be more stable and has a satin finish which results in less cable noise. A light champagne tone lends the headphones a very elegant appearance and raises the T 51 p above the plastic monotony of most – even more expensive – headphones with its all-metal construction.

Perfect to wear

With its metal fully-adjustable headband and swivelling earcups the T 51 i fits perfectly on your head and confirms beyerdynamic’s long-established reputation for producing headphones  with excellent wearing comfort. The ear pads made of super-soft synthetic leather fit the contour of the outer ear thanks to its viscoelastic filling (a memory foam).

Practical, even when traveling

Thanks to the swivelling earcups the T 51 i folds up compactly and fits in the included rugged nylon carry case. A high-quality 6.35 mm adapter is included for listening on premium hi-fi equipment or headphone amplifiers, an airplane adapter is also included so you can enjoy a superior experience of in-flight entertainment.

technical data

Transmission type   Wired
Headphone design (operating principle)   Closed
Headphone impedanceAlso known as nominal impedance. The impedance is the AC resistance of the coils of loudspeakers and headphones in ohms. Since impedance depends on the frequency, it is always specified at a frequency of one kilohertz.   32 ohms
Headphone frequency responseThe frequency response specifies the highest and lowest frequencies reproduced by the acoustic transducer of the headphones.   10 Hz - 23,000 Hz
Nominal sound pressure levelThe acoustical level, the headphone transducer produces to an artificial ear (a measurement device, which simulates a human ear) with an input power of 1 mW (dB/mW @ 500 Hz).   111 dB
ConstructionSound coupling to the ear. A differentiation is made between supraaural headphones, circumaural headphones and in-ear headphones.   Supraaural (on-ear)

"They’re easily some of the best portable on-ear headphones we’ve heard at this price."

[...]

"The Beyerdynamic T51i in-ears give an incredibly insightful performance, revealing the textures of instruments and nuances in vocals. Each frequency is beautifully judged. There’s remarkable clarity and bite at the top, but it’s smooth enough to avoid hardness. The midrange is eloquent and poised. Bass notes are substantial but taut. In rhythmic terms, the T51is possess timing of regimented precision."

[...]

"They’re light, for starters. You wouldn’t expect that from a mostly metal body. And it’s sturdy metal too. These will take a lot of punishment and still come out singing. This lightness helps them sit comfortably on your head."

[...]

"We should mention the closed-back construction, which provides a few degrees of passive noise isolation. Along with the snug (but never squeezy) ear pads, this provides a neat way to segregate oneself from the outside world. The T51is are great for commutes."

[...]

"Verdict: Look no further if you have up to £250 for a pair of on-ear headphones. Beyerdynamic is stronger than ever, and now there’s a remote control. What more could you ask for?"


The sound is convincing

The noble processed beyerdynamic T 51 i has been designed as a portable headphone. We like the materials used such as the headband pad and ear pads which are made of soft leather. The headphone is light and very comfortable also for people who wear glasses. The ambient noise is very well attenuated.

[...]

The sound is convincing and in this price range it clearly plays in the top league. We enjoy the warm and precise bass and the detailed resolution of the music. Voices and acoustic instruments are clearly heard and even prolonged listening is stress-free, as the sound has not been trimmed for effects.

[...]

So these headphones are well suited as a companion on long trips (...)."

The beyerdynamic headphone has a solid stable appearance with its metal components (…). This lightweight is one of the most comfortable on-ear headphones in the test with a top sound. When connected to the smartphone output, the T 51 i supplies powerful sound with differentiated basses and superior details.

At present the best headphone

The look of the beyerdynamic T51i is polarising: With its plain design it looks as if it was made with a metal building set, quite in contrast to the hip competitors with their colourful high gloss synthetic materials. Yokes, joints and headband make a very strong impression, the workmanship appears solid.

[...]

In fact: in the measuring lab of COMPUTER BILD the T51i accelerated considerably and was louder at the same input voltage than most of the competitors (...). In this way you can listen to the music without distortion even in loud surroundings, because you need not to increase the volume of the player. Fellow passengers feel less molested, because the beyerdynamic headphone does not let sound penetrate outwards. The proud owner may be happy about the very clean and balanced sound without any distortion. The beyerdynamic provides powerful and clean, a never exaggerated bass and clear treble. In comparison to competitors (...) there are more details audible with the T 51i and listening to the music is a lot of fun.

[...]

If it has to be the best sound when on the go, the beyerdyamic T51i is the choice. It sounds balanced and neutral, but does not neglect the bass. It also plays loud enough with weak smartphones and convinces with a high comfort of wearing. With a rating of 1.93 it is currently the best headphone that COMPUTER BILD tested.

Both headsets appear to be of a high quality, just as it can be expected for this price. The T51i with its noble metallic appearance and simple, yet modern design is most impressive.

One can state that beyerdynamic does not promise too much, because the new headphone actually sounds excellent, what can already be said before the official presentation.

[...]

The beyerdynamic T 50 p already is a great headphone when you are on the go, but it has been surpassed by its successor the beyerdynamic T 51 p. At last with the beyerdynamic T 51 i, a variant of the T 51 p, there is an on-ear headphone version available for smartphones.
