Question: May I "plug- in" an old Ipod via 3.5 mm cable to aux?
Document: If memory serves, in all my years purchasing through Amazon this may be my first review. But this G-BOOM has inspired me to write... it's that good. I go way back with boom boxes. I still have a JVC Kaboom! that is 14 years old (before the iPod and BlueTooth wireless speaker combination existed).
The audio in cord that is supplied with the boom, hooks into my nano via the headphone jack port, then just hook the other end into your boom. You can use your boom either corded, or uncorded. iPods, iPod touches, ipads. Can be hooked up to your boom, and I'm sure there are other devices. You have 3 hook ups on back of unit. AUDIO IN, USB , A/C ADAPTER. This system sounds pretty good, and I'm a very picky person.
If the battery lasted for 12 hours like some of the other, smaller speakers, I'd give this product five stars. It also has bluetooth support, which is a bonus, but I only use it via the aux input so bluetooth doesn't matter to me.
Those small speakers just don't project sound. In an outdoor setting they're not loud at all.I looked at old school ghetto blasters with Aux inputs. The DeWalt and JVC Kaboom looked nice, but were expensive (at least 200 bucks for the cheapest, heavy, and didn't have rechargeable batteries.
I love these, I bought 2 units, and connected via cable to my Mac Book Pro - use it for picnic dances at the beach. Batteries last forever, and the sound is MORE than I need to cover a 30 x 30 pavilion. Highly recommended
It also sounds good up close & wouldn't hesitate to use it indoors, either. I don't use the blue tooth, but a 30 pin to the aux jack cord from my ipod classic with mp3's ripped at at least 256 kbps, so I'm probably getting the most out of these speakers sound wise. It's sturdy & easy to carry. I don't have to worry about being overly gentle with it.
It does have 3 different eq settings and I have yet to be disappointed with the sound. At times it does sound tinny, and at times it will distort at top volume however at normal volume and even on the loud side the sound is a little above average. Ofcourse the sound does depend on the source. I find streaming pandora from my tablet and my ipod plugged in directly to be above average. Streaming music files directly from galaxy s4, sound was spotty and auto level was turned off.
and walk/ride around with some hip hop joints shooting off your hip joint!TL;DR Built for outdoors, is very loud, and needs to be played loud for best sound (I'd say the 5-10 range, 10 being the loudest (if that wasn't clear)), saves you hella $ on batteries, and is 1/3 the price of anything better - but nothing better is as loud as this. And if you've ever bought a boombox, you want the loudest one there is.
Let me start by saying that I really give the G-Boom a 5, but who reads the 5 stars?My search for a bluetooth speaker began when I wanted to upgrade my little mono speaker, the kind with a AUX plug, that I use for showers and while cleaning the house. I started with the UE Mini Boom, which was pretty much an exact replacement with better audio fidelity and wireless. I found myself throughly enjoying this newfound wireless freedom and decided to see how deep the rabbit hole goes.
I was like, now this is more like it! Big, full sound. I don't know about you, but when I play some metal, I want it to kick ass. I prompty returned the ecoxgear, and purchased the G-boom. If you want something small and portable, this may not be the speaker for you. But if quality sound is your main concern, this is the unit for you. Crank it up, and bang your head!
Answer: Yes, it has a 3.5mm stereo in jack on the back. You'll have to get a stereo 3.5mm audio patch cable. Should be cheap.
