Enjoy your audio almost anywhere and customize it to your specific tastes with the HD 350BT Wireless Over-Ear Headphones from Sennheiser. Whether at home or on the go, Bluetooth 5.0 technology allows you to enjoy audio without cumbersome wires getting in the way. Whether you listen to music, podcasts, or streaming video, what you hear is engineered to sounds as good as possible with support for AAC, aptX, and aptX Low Latency codecs. You can even tweak the sound with the equalizer built into Sennheiser's Smart Control app for iOS and Android devices.
These wireless headphones can send as well as receive. Dual beamforming MEMS microphones built into the headphones allow you to interact with a paired smartphone. You can conduct hands-free phone calls or interact with your phone's digital assistant. There's a dedicated button that activates interaction with either Siri or Google Assistant. Use your voice to ask questions or give commands to control playback and calls. Regardless of how you use the HD 350BT headphones, you can do so all day thanks to a rechargeable LiPo battery that provides up to 30 hours of power.
