The original Bose Sleepbuds were not exactly a rousing success. Long-term testing revealed inconsistent battery life, random shut-offs and unreliable Bluetooth. But the company claims it has fixed those problems and landed on a product that should please its demanding customers.

Brian Oh, our senior video producer here at Engadget and I have both been testing the new $250 Bose Sleepbuds 2 to see if they can help us rest a little easier at night.

Brian, like many of us, has trouble getting to sleep and staying asleep.

The root cause of his sleep issues are very similar to my own: an overactive brain. Neither of us can sleep in silence because our inner voice literally WILL. NOT. SHUT. UP. For me this has led to a lifetime of chronic insomnia that has at times required medication. There are, of course, differences in our situations. Brian tends to be a light sleeper, waking up at every little sound including his snoring dog. I, on the other hand, could probably sleep through armageddon. (I still frequently wake up in the middle of the night, just usually due to back pain or night terrors Im a blast to share a bed with.)

After two weeks we can both report at least some success. The bigger question is, can a wearable sound machine ever be worth $250?

Now, I want to be clear: The Bose Sleepbuds are not headphones. You can not use them to listen to music or podcasts. They cant answer phone calls. You load a selection of soothing sounds on them from Boses library and thats it. And yes, you load the sounds on them, not stream. The Bluetooth here isnt any good for streaming audio, and frankly its pretty damn slow for transferring even the small files were talking about.

The Sleepbuds are very much a single-use gadget. So, everything rides on how well it does that one thing. In order to succeed they need to be small and comfortable enough to wear all night. They need to block enough sound to keep the nonstop traffic outside at bay, or at least muffle the loud snorer next to you. But they also need to let enough in that a smoke alarm will get you up and moving. The soundscapes also need to be pleasing to the ear, without obvious seams, and cover a wide range of styles to suit peoples tastes. Lastly, they need to be easy to use because no one wants to fight with a buggy and complicated app as theyre getting ready for some shuteye.

Lets go through these requirements one-by-one, starting with comfort.

Are the Sleepbuds 2 comfortable? Yes, with some caveats.

The soft-touch plastic and antifriction coating are honestly better than basically any earbud, wireless or otherwise Ive ever worn. Brian also had few complaints. These have all the hallmarks of the sort of premium products Bose has built its name on. And the seal keeps out enough of your environment that you might not even need the sounds if all youre doing is trying to keep a noisy radiator at bay.

My wife is an incredibly light sleeper; she requires absolute silence. If I get out of bed to use the bathroom in the middle of the night, she shoots up like someone just kicked in the front door. So, Ive tried to wear earbuds to bed before since our sleeping habits are so different, but I just cant do it. I had no problem passing out with the Sleepbuds in my ears, though.

As the night drags on things get a little different.

Brian, for instance, is a side sleeper, and while he found the buds comfortable enough in a vacuum, he had to position his pillow just right so that it wasnt shoving them deeper into his ear and disrupting his sleep.

I toss and turn a lot in my sleep and almost every night either I would end up in a position where the buds were pressing uncomfortably into my ear, or they would just fall out. Brian also had one of the buds fall out a few times and we can both confirm that trying to find these tiny earbuds in your bed while half asleep without glasses on is a surefire way to ruin your night.

So, for short periods of time in a controlled environment, the Sleepbuds 2 are extremely comfortable. But, in actual use its a bit of a mixed bag.

The same is true of the sound selection. It took both me and Brian a few nights to find the sounds that worked for each of us. He preferred the steady hum of the Warm Static under the Noise Masking category, while I was drawn to the ambient drones of Wanderlust found in the Tranquilities section.

The Noise Masking, Naturescapes and musical choices cover a lot of different ground that should satisfy a wide variety of tastes. There are 50 sounds in total, which is pretty decent and theyre all perfectly seamless, too. Yes, you can tell theyre relatively short audio loops, but youd be hard-pressed to identify the loop points.

Now, personally, I found the Naturescapes and Noise Masking settings to be almost oppressive, despite the fact that I often use nature sounds as a sleep aid. (Im partial to crickets and thunderstorms.) Brian, on the other hand, thought the Tranquilities were just too distracting and could only imagine using them for meditation.

And, look, you cant please all the people all of the time, but I like my nature sounds. The thing is, I just dont like the nature sounds here. The Boardwalk, for example, sounds less like waves crashing on a beach and more like someone caught a fraction of a second of a wave and looped it until it was basically indistinguishable from whitenoise. With no variation or movement, the Naturescapes just dont sound natural.

This would be less of an issue if you could simply pump in your own sounds. I often like to fire up Headspace to do a wind-down exercise and meditate before bed, but I cant use that with the Sleepbuds. And I have even created my own sleep sounds from field recordings Ive taken of storms, crickets and katydids. If the Sleepbuds worked just like any other set of Bluetooth earbuds I could simply listen to that. But, youre stuck with what Bose gives you.
