The Sennheiser HD 350BT is a Bluetooth headset that promises quality sound at an intermediate cost. The great thing about the device, launched at CES 2020, is the long-lasting battery, which promises up to 30 hours of music playback. With an over-ear design, the model physically promises acoustic isolation, even without active noise cancellation.

The brand printed a minimalist style, with a black or white finish, and almost no eye-catching visual details. Being an over-ear headset, the HD 350BT has acoustic shells that wrap around the entire ear.
For the user’s comfort, the pieces are padded and have adjustable stems, ensuring a good fit for the head. The part of the shells has a joint that allows them to be moved laterally, which results in more comfort when hanging the device from the neck.
The body is made entirely of plastic, which guarantees its lightness – the HD 350BT weighs 238 grams, relatively little for an over-ear model – but makes the product more fragile. The headphone folds for easy transportation.
The HD series model has a sensitivity of 108 dB, which means good volume from the transducers. It is worth remembering, however, that the maximum recommended volume for hearing health is 85 dB.
The frequency response of the drivers of the HD 350BT ranges from 18 Hz to 22 kHz. In other words, the headphone can reproduce ranges within this range, indicating good coverage of bass, midrange, and treble. In terms of sound quality, the most attractive detail on the technical sheet is the support for low latency codecs, such as AAC and aptX. This feature provides good synchronization between audio and video, an important differential for those who want to use headphones to play games.
The device boasts Bluetooth 5.0. The feature gives the HD 350BT inherent capabilities such as a range up to 240 meters and transfers up to 2 Mb/s. In addition, the headset includes multipoint connectivity, which means it can be connected simultaneously to multiple devices, such as your cell phone and laptop.
It is also possible to customize the sound coming out of the headset to the user’s preferences. Through the Smart Control app, available for Android and iPhone (iOS), the user can use the equalizer to highlight the bass or lower the pitch of the tracks, for example.
The app also has special sound modes, such as podcasts, which makes audiobooks and podcasts easier to understand. The “Transparent Listening” mode, on the other hand, allows you to listen to music in such a way that you can still hear the surrounding sound. In addition, the app can be used to update the firmware of the headset.
Another feature of the HD 350BT is the button to activate the voice assistants Google Assistant or Apple’s Siri. With it, the user can take advantage of the device’s microphone to control it by voice commands.
One of the big stars of the HD 350BT, the battery has a capacity of 300 mAh and takes approximately 2 hours to be fully charged. When fully charged, it guarantees 30 hours of non-stop music playback, according to the manufacturer.
The charging is done through a USB-C cable, which comes with the over-ear. This means that the listener does not need to charge the device every day, and can even leave the charger at home without fear of having to refill it at any time.
