Teenage Engineering OB–4 Portable Bluetooth Wireless Stereo Speaker with fm-Radio and Long-Lasting, Rechargeable 72 Hour Battery Life (Glossy White)

I own a handful of items that Teenage Engineering has released and this one is hands down the most versatile. Whether you're recording/playing music and using this as your audio output or just doing chores and whistling while you work, or looking to have a blissful atmospheric sound playing ambience for you...This has it all. And I find this to be the one I go back to often. If I had one gripe about it, is the lack of options in the app that can also be accompanied. You don't need to use the app to use this device at all. And the other gripe might be, that I find the the bluetooth's latency to be a bit laggy at times. But other than that, I love the output volume, which tends to rest in a bit more bass-heavy space. I take this thing everywhere in the house, from the garage to the office to the living room to the kitchen, when I'm showering...You name it. I've run Pocket Operators and the EP K.O. II through it and it sounds pitch perfect. I can't recommend this enough.

Amazing sound and function. I absolutely love it. Can't imagine wanting any other type of portable speaker. Easy to carry, connect, and haven't had any drops in bluetooth. All works fine. Battery life is great. This is something you buy to last a very long time.

I'm giving this a 1 for a very good reason. This is advertised as a "long battery life speaker" promise you it'll last you 72 hours. Don't know if a faulty battery was put into mine but I can easily get 30 minutes fully charged before dying which is disappointing because I thought this would be perfect for a mobile synth rig but false I can't use it without it being plugged in. My other criticism is that I feel like the effect aren't fun and poorly designed and I'm mainly referencing the "ambient mode" I thought it would be something fun maybe add reverb or delays kind of like a pedal but no it is just a ambient synth track that bleeds into your audio which really takes away from the creativity and really just defeats the purpose. Other than that it does sound really good. $600 good? Not quite more like $200 good but yeah the loops are cool too but still over priced. So the takeaway? Poor battery life, poorly designed effects and you get a decent sounding speaker that does loops I guess. Id retail this for $200 not $600

The media could not be loaded. The absolute single best speaker of its size, plus it is truly a synthesis of engineering and art. I've tried SO MANY bluetooth speakers, and this one is, to quote Tina Turner, "Simply The Best". It is a little pricey, but you DO get what you paid for here. I give these as gifts and everyone impressed their friends with it! (also try the weirder colors, not just black, they're ALL amazing). They also update the firmware regularly with cool new features. It would be very VERY difficult to do better than this speaker, I mean, you could make it cheaper but sometimes the more expensive items are a bit better!

this is a nice speaker that was made to be much more than a speaker, and at first when i got it, was very displeased, as sounds on it were just much much different than what i have used for years past; but this is largely in part with I am using lower-mid grade speakers and this is not that.First of all, this thing is a BOOM BOX.I cannot really play any of my black metal / heavy metal / anything metal louder than 35% in my apartment before it exceeds all over devices sound.You can feel the music at all sound levels. Truly. Which i find to be very unique.And this is much more than a speaker, and if you dont read the possiblities of what this does before hand, you will be a bit sad when you consider the price to speaker. but this is an instrument.full fledged, with 2 hours of playback on the tape, mixxing up some of the craziest sounds from just random radio snipets / song snipets, along with scratching, speeding up, slowing down, changing pitch, looping, etc. you have to take some time to learn all these functions as you have 4 Human interface inputs on the device with about 16 or more actions associated with them, being a combination of a button held here and dial moved there, two buttons, etc.comes with good documentation on all the use-case.oh and this battery is the best of any bluetooth speaker ive ever seen with the quality of sound putting out.i have left it on for two days playing music off and on while always atleast connected to BT before it tends to show me red on the light and that means charge it.would be good for parties, and is a sturdy device. but high value, and small. easy to steal so dont set it down!

Love the battery life but its value really isn't it. Its great to use i love how the buttons feel and the knob has a great feel but the speaker has horrible input delay to the point that I pause I song and it takes 5 second to finally stop.

Why did you pick this product vs others?:Has always been a big fan of teenage engineering and this radio is a hack of a sound device. Crispy red color works well with any interior backdrop is a bonus.

I love TE and all their quirky devices and this “magic radio” is no exception. It’s got a premium quality feel to and the sound is REALLY good. The functions are nice and unexpected, but you’ll quickly start using this device as a BT speaker if you’re not too heavily invested in music production. And for the price point, I can’t really justify any of this as a selling point. You’ll find much better BT for cheaper elsewhere. The radio aspect combined with some of the effects the OB-4 comes with quickly wane. Unless you have a real nice discretionary spending budget, then go ahead and purchase this exceptional radio/BT speaker. If you don’t, please trust me on this one when I say you REALLY DON’T need it.
