  • Overview

    The ATH-WS55i Solid Bass headphones feature an in-line three-button remote that provides the ability to control volume, play, pause, fast forward and rewind music playback functions on compatible Apple devices. The remote also lets iPhone users answer calls over the headphones, or while talking via Skype or VoIP on an iPhone, iPad or iPod touch®. The microphone has an omnidirectional pickup pattern (it picks up sound from all directions) and is designed for high-quality, intelligible response, enabling the wearer's voice to be clearly transmitted without having to speak directly into the mic.

    The Double Air Chamber System delivers incredibly full and textured bass without sacrificing the astonishing clarity and fidelity for which Audio-Technica is renowned. Audio-Technica’s sophisticated driver technology and superior components deliver exceptional power handling, maintaining clarity of sound throughout their extended range. The headphones feature 40 mm drivers for powerful sound and efficient signal transfer.

    • Q:

      Do the headphones with mics use a CTIA standard or OMTP standard connector?
      Asked on 2/24/2015 by Rand from San Francisco, CA, USA

      1 answer

      • A:

        Good question. The ATH-WS55iBK are CTIA. However, the single "i" in the title means that these particular headphones are MFi (made for iphone), which means that they are specific for use with Apple products that feature a CTIA communications jack. The WS55iBK will still work with Android CTIA devices, but will have limited functionality (i.e. the volume control for the WS55iBK will not work on Android devices, and will be at full volume). Any headphone with an "iS" in the title will work with either iPhone CTIA or Android CTIA. This also subsequently means that "iS" headphones will work with PS4. Please note, there is no iS version of the WS55.

    • Q:

      Will it work for non-Apple phones?

      I'm looking for a top headset/mic for my cell phone. I use a Samsung Epic Touch.

    • Q:

      How do these compare to the m50?

      I'm looking for a good closed set of headphones. iPhone compatibility is a huge bonus for me, as is the removable cable but I'm not willing to sacrifice significant sound quality for them. I listen to mostly chill music like fleet foxes, bon iver, jesse woods, iron and wine, etc. but occasionally will listen to some house, dubstep or metal.

        Thank you for your inquiry. This is hard to answer because headphone preferences are very subjective. Also, they are designed for different uses. The ATH-M50's are designed for studio use, so the frequencies are somewhat flat (not over emphasized). As a recording engineer the ATH-M50's are my favorite headphones. The ATH-W55ibk will have an enhanced low end.
