Thank you for inquiring about the Mini Capsule I just recently purchased.We have just returned from a cruise and Thanksgiving with Family.
In regards to the .....
AYL Portable Mini Capsule Speaker System with 3YR Guarantee with Rechargeable Battery and Expandable Bass Resonator for Smartphones, Tablets, MP3 Play
It perfomed flalessly !!!! I tested it at home and was Astounded that much Quaility Sound could come from such a small device!! We boarded for the cruise on a Monday. ASAP I got out the MP3 player and hooked up to the Mini Capsule. It played 24/7, and was the last item I packed when we debarked on Saturday morning. This system is used when we travel so we don't have to cart a bulky Satelite Radio system along with us. I purchased the Mini as the speaker we have has started to have some static. It does not have the quailty sound of the Mini. I will probably purchase another to have 2 speaker sound. Like the feature that allows multiple speaker hook-up.
Again, Thanks for the e-mail inquiry on the performance of your product.The personal touch that is so lacking in today's world! The majority of merchants today forget the product and the consumer as soon as the sale is completed!
We wish you and your family success in your endever.

just replaced my old monitor with a new one that has no built-in speakers.
sound from my mini mac is less than acceptable, so time to speaker search.
looked at stereo speakers and thought no, desk top room was a t a premium. came across this little unit.
found a winner, with a full range of sound. what an improvement from my old monitor speakers.
now if you are looking for audiophile quality, look else where, but this little speaker packs a punch and does not use up usb ports since
it is rechargeable, a Plus! if your computer desk is in a corner like mine, place the speaker as close to the corner as possible.
the bass sounds fuller!

These little speakers are AWESOME. They are very small, but they still have great sound. You can collapse them and carry one easily in your pocket. You can buy more and plug them together for more sound. I bought one for my husband who likes to listen to music on his phone while he works and he loved it so much I bought two more. They are pretty durable too because he's dropped it a few times and it's still working like new.

Let me first say, I was skeptical about purchasing this mini-speaker. The built-in speakers for my Dell 15R laptop just weren't doing the job when I needed to Skype or even watch movies online. I was presented with the challenge of finding affordable speakers that didn't take up a lot of space, but all of the competitions offerings were oddly shaped & bulky.

I received the AYL speaker with a charge of about an hour. I did some testing with a song played from my laptop. Here's a comparison between the AYL speaker and the built-in Dell 15r speakers:

The volume was set to 100% on my laptop and also 100% on the AYL speaker.

*AYL speaker:
At 30ft away with a wall in between, I could clearly hear the audio. It was also loud.

*Dell 15r built-in speakers:
At 30ft away with a wall in between, words would barely be made out from the audio. It was similar to having headphones on with the volume set to below 30%.

Pros:
Small form factor
Collapsible and extremely mobile
You can chain them together for possibly a surround-sound experience.

Cons:
Battery life, but what do you expect from such a small package?

Whether you're on the go or you need an external speaker upgrade for your computer, then this speaker is the way to go.

I squeezed a mini-stereo inside my mountain bike's water bottle frame and added styrofoam to keep it tight. I added this speaker to the open top of a handlebar bag because it's closest and faces my ears. The handlebar bag's closed zipper's holds it firmly in place with the speaker side clear of obstructions and facing upward towards me.

To improve the speakers lithium battery performance between charges, I set the stereo's volume output to 9/10 (it seems to run forever when not powering its own internal speaker) and keep the AYL speaker's volume lower at 3-4/10. I use the AYL's control to adjust the volume.

The greatly improved sound quality, volume and warranty is worth every penny. I did wear headphones or earbuds that became hot, sweaty and noisy from cables bouncing around. This open air sound is very nice and much safer on a bicycle.

Update 5 June 2017: Working perfectly. I added a second speaker yet lost some bass as expected. Therefore, I keep the extra on my bike as a back-up.
