Deep Sleep Instrumental Music

It's a beautiful experience listening to deep bass or instrumental music. Call quality is great too and they ares super comfotrable for wearing 2-3hr at a stretch. There are way too many features that I could not test. The connectivity to multiple devices is not very intuitive (TBH I have not seen the tutorial included in the app so it's partially my mistake) Overall, highly recommended.

Love the full sound this puts out. I bought this to use with Nucalm's Deep Sleep. Now I sleep great.

I listen to classical music and acoustic modern jazzy music (97% instrumental). These headphones sound natural and feel comfortable on my head. If you like the K701 then these are much better. NOTE: They are not bassy; i.e. bass is neutral.

I sleep with these on listening to deep sleep recordings. It says only 6 hours per charge but they were still at a 60% charge after a full 8 hours!These things are extremely comfortable with very good sound that will go louder than I can handle with zero distortion.As for distance, I left my phone in my upstairs office and went to the back of the house to drag the garbage to thew curb without missing a note.These headphones surpass every single claim made by the manufacturer!

I've spent around 30 hours with the OP-Z and I've had a tremendous amount of fun. While I bought the bundle, I have yet to use the lab module. I do like the rumble module much more than I thought I would. It feels a little gimmicky at first, but I find myself missing it when I turn it off to save battery (the module seems to drain the battery pretty quickly). The one and only negative is the fact the the battery arrived completely dead. It must have been sitting on the shelf for so long that the Li-Ion battery went into a deep sleep mode and it refused to charge. I followed the instructions to revive the battery on the Teenage Engineering site, but had no luck. Finally, I found a Reddit post suggesting a "jumpstarting" technique that required me to strip a USB cable down the the bare wires and hold the wires to the battery contacts for a few seconds. This sounded a little nuts, but I gave it a shot and sure enough the battery was once again capable of charging. The battery issue appears to be relatively common. If anyone else happens to run into the problem, this is the video that saved me the trouble of exchanging: https://youtu.be/WFd1CXbRsvs (titled "revive cellphone batteries from deep sleep")

For deep listening to music these are really nice. Great sound!

Great little addition to any instrumental setting

I bought this because I wanted to hear fm radio music, specially before falling sleep. This radio satisfies me in clarity of reception of music, contrary to other brand radio which gave poor reception of classic music.

I can sleep at night knowing all the music I've spent weeks loading onto the NAS is safe.

i bought this for my bedroom along with the samsung sound bar so i could access youtube and get sleep music. it works great and i sleep all night long. in my living room i have a samsung 52" tv and sound bar. it is perfect.
