Great little 4" speaker
585065
One has to consider two things on this product:
1) It's only 4 inches.  One can't expect 10" sound from a 4" speaker.
2) It's around 20 bucks (including shipping) for a PAIR of *four way* speakers, with mounting hardware.  That's about as cheap as speakers come.

Agreed, it doesn't have as deep a bass as one would wish... but how much bass can one expect out of a 4" speaker?  I found it to have pretty good highs; the tweeters are about 1/2" diameter, plus a tiny high-range in the middle.  I found the sound to be acceptable for my uses.  That doesn't mean it will be spiffy for all uses; one would certainly want to pay attention to ohm and wattage ranges.  Overpowering this would be asking for trouble. I wouldn't use this as a primary auto speaker, but would probably make a good supplemental or room speaker system

But if you're looking for a good-quality, attractive wide-range speaker, this does a pretty good job.

This is a shiny little speaker that is very portable as it is about 7 1/4 in. long.  It has a clean, curved design that angles the drivers for noticeable stereo.  The minimalist controls are along the top and a blue LED indicator for Bluetooth is behind the honeycomb grille.

It has an 850 mAh lithium-ion battery, so it will play about six to eight hours without an external power source, depending on volume and Bluetooth or auxiliary input use.  It charges with a USB cable, which is included.

The dual 2 watt drivers put out quite a bit of bass, considering the speaker's size.  There is no distortion at normal listening volumes and the audio is very enjoyable.

This is a nice personal speaker to use with a laptop or smartphone.  The Bluetooth will allow roaming up to 30 ft. or so and will accept NFC connections.

Neon Electronic provided a speaker for evaluation and review.

This is a great little speaker and is a good value (I purchased mine for 17.99).  I was used to listening to music from the little speaker on my iPod.  I occasionally put it in a bowl to amplify the sound somewhat but really wanted a speaker I could use around the house.  The AYL speaker is perfect for my needs.  It has great sound for a portable speaker and can be really loud if you choose.  It's easy to use.  I like that you can change the volume directly on the speaker or the iPod.  The battery lasts for a long time.  I've been using it daily for weeks and haven't needed to charge it yet.  It's nice that you can collapse the speaker for easy storing and travel and the mesh bag that comes with it is a pleasant and appreciated addition.  The feature that allows you to connect multiples of this same speaker together is great and I can see how it would further enhance the sound, but for my purposes the one speaker is enough.

I love this little speaker! The sound quality is great for the price. I've been using it in my shower. The suction cup is pretty powerful; I used it for thirty minutes or so and it never moved.

The speaker is on the bottom of the unit, so the sound sort of bounces against whatever surface you have it stuck to.

I love being able to answer the phone if necessary. Changing the song/pausing directly from the speaker is helpful, too. I could not, however, change the songs using Pandora or 8Tracks.

For the price...great bargain.

I was looking for a speaker for my iPad that I could easily travel with and this fits the bill.  It's small enough to put in a purse or even a pocket and has a big sound.  I use it for watching movies and listening to Pandora on the iPad.  We've  started taking it out on the deck for some dinner music; choose some tunes on Pandora, take the JBL Micro out with our tray of food, and we're set.

First off let me tell you that VTIN makes some really good speakers, I have one I bought for a tubing trip and wanted another one I could leave in our camper for use around the campfire and poolside. This speaker packs quite the punch for its small size. Its easy to connect with Bluetooth plays a nice little melody when connected. You can control your media with the controls on top/side of this speaker. It has some really nice bass, which again for the size was a surprise. One other nice feature is if you get a call while listening to music you can answer and talk through this speaker as it has a mic as well.  A very nice speaker at a very affordable price.

This is a really nice little speaker.  I use it to sit on the porch and listen to my iPod.  Very impressive sound for such a tiny thing.  I wish it had a little more bass but that is just a personal preference.  Worth the money!

Just received this speaker and played with it for a few days.  Overall, I really like it!

Its well built and it feels solid.  My toddlers were tossing it around and it was not an issue.
Its very small.  Much smaller than other speakers (most of which were tube shaped) I have handled
It is VERY directional.  One side kicks out bass, the other is the main speaker.  If you are facing the main speaker, you aren't getting much bass.  If you are facing a side, the volume is noticeably lower.  The tube shaped speakers are much better at being omni-directional.
At low volume, the sound is clear and most genres sound surprisingly good. Pleased with the sound quality.
It can go to to about 50% volume before the sound clarity begins to degrade.  This tiny speaker goes pretty dang loud, so 50% is still pretty loud.
The bluetooth is great.  Connects instantly, stays connected, good range.
All the buttons work well and are easy to use.
Would be nice if the strap was easier to remove.
I like the tripod thread, I have a little joby that I have with me for pics/videos often and I can prop up the speaker on it.
Personally I think it is an attractive design.

Overall, for the price, this speaker is great, but not perfect.  I would give it 4.5/5 is that was an option!

Great sound for a tiny speaker.  Could use more bass sound, but the quality is very good for its size. No tinny sound and vibration at the higher volume.

Great little speaker. Sounds a bit flat compared to my bose soundlink mini, but it does the job for a fraction of the price. Battery life has been great, uses micro usb which is great, charges fast.

very nice bluetooth speaker.  at 9x3.5x4" it is still small enough to be portable, but big enough to give ample sound.  the sound is punchy with a good amount of bass.  it does fill an average size bedroom but it is not as spacious or detailed as a full size stereo system.

the "Turbo" mode does boost the loudness but then the sound gets a bit distorted so i prefer not using the Turbo mode.

the bluetooth connection is handy especially for use with an ipod or ipad.

Great little Bluetooth speaker. Compared to a similar speaker, this one seems less oriented toward bass and strives for a more balanced sound. I'm a little bit of an audiophile and understand the limitations of speakers of this size. That being said, this speaker sounds very clean and I often use it when I'm performing power ballads in the shower. The only downside is that it's not quite as loud as other speakers out there, but this may be to avoid causing distortion when cranked up. I'd recommend it to anyone looking for a great little speaker to have around when you just want a good listen, but it probably won't impress those looking for a super loud and bass heavy speaker.

Sounds great for a little speaker when you don't want to hook up to a bigger setup

Great little speaker!

I bought this to tag along when going to the beach or any outside small gathering.

Cool design.  Very portable.

Pretty good sound quality from a little speaker.  Volume is acceptable.  If you are trying to rock a big party this is not what you want.  If you want to listen to music and talk to your friends this speaker is great.  I usually play it at half the volume.  Although, it is good at playing on full power without any noticeable sound distortions.

Charging is easy by the usb cord.

Very easy to set up wireless connection.  I have connected my samsung s3 and a laptop without issues.  Direct link cable also works well.

It looks to be pretty sturdy.  It took a few tumbles and works great.
