Beyerdynamic T51i Portable Headphones Review

The Beyerdynamic T51i headphones is a compact headset made for audiophiles and it is noted for its good sound quality. This has the distinction of being specially designed for iOS devices (iPod, iPhone or iPad for example) and even come with a remote control.

The bold logo of Beyerdynamic is seen on the ear cups and they provide an aesthetic contrast with the matte brushed or sanded surfaces. It has a very elegant and distinct appearance with its mostly-metal construction.

The T51i headphones combines a particularly serious bass response and clear and transparent highs with a characteristic that is common to all Tesla headphones: maximum efficiency and very little distortion. The result is a clear and powerful sound across the entire frequency spectrum, even when played at low levels. With its closed design, the T51i very effectively repels ambient noise.

This headset operates speakers manufactured by Tesla technology, thus guaranteeing sound reproduction that is both precise and powerful. The T51i delivers sound without compromise, judging by its new and improved transducer arrays.

The transducers are contained in metal hulls supported by a robust structure. The Beyerdynamic T51i headphones provide excellent comfort, thanks to its ear cup memory foam which adapt to the contours of the outer ear. The headphones are padded with foam to accommodate your ears without applying too much pressure.

With its metal hoop and its reversible ear cups, the T51i headset perfectly fits the shape of the head in conformity with the reputation of Beyerdynamic’s range of headphones which is a tremendous wearing comfort. The headband adjusts to your head and does not leave a large gap at the temple like many headphones do.

The Beyerdynamic T51i headset has a microphone and a remote control and is fully compatible with iPads / iPhones. With the remote, users can change the listening volume, select tracks and answer incoming phone calls. These functions will also be available with a smartphone Android or Windows (except volume) via the supplied adapter.

Light weight at about 7 ounces and an almost metallic design, the headband is not articulated but the headphones can be folded and stored easily in the specially designed case that is shipped with the headset. The ear cups can be rotated by up to a 90° angle. With reversible ear cups, the T51i headphones can be folded into a compact shape and easily stored within the carrying bag.

To connect the headsets whenever you are on an airplane, simply use the airplane adapter provided with the product package.

Accessories included in the product’s packaging include a carrying pouch, plane adapter, 6.35mm adapter, adapter for devices other than iOS etc.

    I love the sound quality though the material used for these headphones feel kinda cheap. Overall you get what you pay for.

  2. Mickel Shlutz says:

    Not a big fan of the “other” commercial brand headphones so decided to go with beyerdynamic which seems more legit. Pricey unit but very well worth it at the end of the day. Recommend to anyone looking for that alternative product.
