BeyerDynamic DT 880 Premium Headphones 600 OHM (491322) with Slappa HardBody Headphone Case, FiiO A1 Port. Headphone Amplifier & 32GB MicroSD High-Speed Memory Card

BeyerDynamic DT 880 Premium Headphones 600 OHM (491322) with Slappa HardBody Headphone Case, FiiO A1 Port. Headphone Amplifier & 32GB MicroSD High-Speed Memory Card

Designed for Home Stereo and Relaxed Listening The DT 990 Headphones with 600 Ohms proves its power when connected to a hi-fi system at home or with an Amplifier This is the 600 ohm version of the DT 880 Premium line, designed explicitly for use with dedicated stereo equipment such as home theater systems and headphone amplifiers. Conventional headphones with lower impedance ratings offer higher volumes at the same level of input, but need heavier drivers to compensate for low impedance or risk sounding muddy and distorted. The lower mass of the drivers of a higher-impedance headphone delivers unparalleled clarity and response, but takes more power to achieve the same loudness. So a higher-impedance headphone such as the 250-ohm DT 880 is ideal for use in home stereo applications, where clarity and dynamic response are paramount, as well as for use with high-performance home theater equipment and headphone amplifiers. A gold plated 3.5 mm stereo jack with 1/4" inch adapter is included and is therefore suitable for use with almost all headphone amplifiers. Semi-Open Back Design with Adjustable Headband and Velour Earpads The DT 880's semi-open, over-the-ear design offers slightly increased sound isolation and reduced noise leakage, while retaining the high fidelity normally associated with open-back headphones. The adjustable headband lets you easily create the perfect fit for extended periods of listening comfort. Anywhere you need high-resolution audio performance, the ...

    Beyerdynamic T51i Portable Tesla Hi-Fi Headphones Apple-Certified Remote & Mic (715603) with A1 Portable Headphone Amplifier Silver Bundle

    Beyerdynamic T51i Portable Tesla Hi-Fi Headphones Apple-Certified Remote & Mic (715603) with A1 Portable Headphone Amplifier Silver Bundle

    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. Works on your iPhone and others - 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...
