Sennheiser HD 350BT Reviews

Good Value

By Brian
Rated 4 out of 5
Date: 2022-11-21

I am comparing these headphones to Bose Soundlink ii wireless headphones which are twice the price. The Bose are better in terms of sound quality, build, and aesthetics but are they twice as good? No. The Sennheiser's provide reasonably good sound quality acceptable for non-critical tasks like entertainment, zoom meetings, etc., and decent materials and build quality. They are light weight. The head band is made of a plastic that is less flexible than I would like. I fear after several months of daily use, taking them on and off repeatedly will stress the material and it will fail. Time will tell. Aesthetically, they are a bit clunky compared to more $$$ brands.

Great for video with Aluratek Bluetooth

Sennheiser HD 350BT Bluetooth works very will with the Aluratek Bluetooth transmitter (that I also purchased at B&H) for video streaming of cable TV shows and also movies from Apple TV. Lip sink is very good. Pairing is easy and once paired, all you have to do is turn the headphones on and your good to go. The headphones stay paired. Sound from the TV and Apple TV box is adjustable right on the headphones and works well.

I've owned Sennheiser headphones before and respect them for quality, reliability, at a good price. Could have gone with more expensive models but these fill the bill for me.

Sounds great, the mic... eh...

I actually really love the sound quality of these, and as someone who can't tolerate noise-cancelling headphones, these block out so much sound when I have music cranking that I don't feel like I am missing out. Super comfy as well. My only two quibbles is that they don't auto-power off, and the microphone. I have tried talking on video calls to people, and it's so bizarre. It's like the mic picks up and amplifies all the sound around. It is... so weird. Still. LOVE the audio quality.

Great sound!

These headphones were very easy to set up, have great sound, and long time between charges.

This was a great purchase for sound quality and helps block outside noise. They are big but that does help cup the ear for that sealed in sound.

Can I connect two of these to one transmitter at once? My wife and I listen to old time radio shows together, so one signal and two receivers is the plan. Thanks. JR
Asked by: JR
Yes, the Sennheiser HD 350BT is capable of connecting to a bluetooth transmitter. Keep in mind the transmitter needs to have the capability of connecting to two devices at the same time. We carry the Twelve South AirFly Pro Bluetooth Receiver and Transmitter which can support two headphones at at time.
