The Sennheiser HD 350BT sounds great, but it is not perfect. The company got rid of the headphone jack, so you can only listen to music through Bluetooth streaming. The headphones are small and easy to carry, but the ear pads may be uncomfortable for a lot of people. Learn about the Sennheiser PXC 550-II if you want to support the Sennheiser brand but need a more comfortable design.
The Sennheiser HD 350BT has a stylishly simple look. We tried out the all-white version, which is also available in all-black. With their light grey ear cushions and muted gold Sennheiser logo and branding, they look cool, maybe too cool.
The ear cups twist left and right and are hinged to the band, so they can fold down into a neat bundle that is easy to store in a bag or backpack. The finish is nice, but the construction isn’t very strong. This makes them easy to put on, but it doesn’t give you much confidence in the long run if you tend to handle your cans roughly throughout the day.

Where to get Sennheiser HD 350BT?
The HD 350BT are just below the HD 450BT. Unlike their more expensive sibling, the HD 350BT don’t have noise cancellation, but they do support aptX for higher quality playback and aptX Low Latency for better sync when watching Netflix and YouTube on a mobile device. Sennheiser makes an app for iOS and Android that works with the headphones and lets you change the EQ and handle firmware updates.
Overall, we liked how easy it was to use, but it’s important to note that there’s no 3.5mm minijack, so your only option is to go wireless. This makes it hard to use them for in-flight entertainment or to save power by plugging them in. The Sennheiser HD 350BT headphones are light at 238g, and the ear pads are very comfortable.
The right cup has a USB-C port for charging, a power port, a Bluetooth pairing button, and controls for volume and playback. The controls are set up so that they work well, and you’ll learn how to use them quickly. There aren’t that many accessories to choose from. Due to its low price, it doesn’t come with a carrying case, but you do get a USB-C charging cable.
