Decent speakers for their size, but be sure to manage your expectations
595061
A2+ are decent speakers, especially for their size. However, make sure you set your expectations as to what they are and are not. These speakers look really cool, especially in red. The sound quality is great for the highs and mids. Crisp and clear with good separation of instruments. Certain kinds of music, like acoustic guitar sounds fantastic. The lows however are definitely lacking, even after breaking these speakers in. They have this mid bass thing that works okay, but if you listen to music with heavy use of bass, you will be wanting more. I though about getting a sub, but that would defeat the purpose of having small speakers because I'm limited on space.

Ultimately, I decided to return the A2+ and picked up a pair of Vanatoo T0. They are about the same size if you are using the A2+ with a stand, but sound much better with plenty of bass, as well as blue tooth, optical in and a remote. I'm much happier with them.

It's tempting to mount small speakers on the walls, but there's just no way they'll sound as good as putting them on stands away from the walls. These stands seem to me to be a good bargain for very small speakers (it doesn't hurt that there's very few options in all of Amazon, though). The assembly was easy, and there's a plenty of mounting options included for most small speakers (I have Mirage Nanosats). I did have to make a quick run to the hardware store to get a bolt-washer-nut combo to make it work properly with my speakers, but you'll likely not need to. The bases are black-painted tempered glass which look nice using with either the gloss side up (with logo) or the matte side up (although the second pair I received was quite a bit better looking on the underside than the first).
Update: after a couple of months, these have not held up. Any movement at all can strip the threads of the base of the rod where it bolts to the glass plate, so don't plan on moving them for cleaning, unless you're very, very careful. Too bad they're so disposable, because they do look nice. Should have been tipped off by the price.

In reading the one and two star reviews, I am at a loss to understand what people honestly expected from this speaker system.

Do you not read the specs before ordering? Or look at the size of the speakers?

Bottom line, these speakers put out a reasonable level of a reasonable quality of sound. If you are looking for "hi-fidelity" then these speakers are not for you. If you want the convenience of being able to listen to your Sansa without headphones (by the way, the sound quality is better through your headphones then through the speakers) along with charging your player and are realistic enough to understand that a $30-40 speaker set which is barely bigger than the MP3 player itself is not going to blow you away sound-wise then these speakers are for you!

No, they don't have a great deal of base and can be kind of "tinny" sounding. That said, your MP3 player comes with a built-in equalizer that you can adjust to mitigate this. We've used ours during a party with 20 people and it was loud enough to be heard even with the conversation. Not sure how loud people expect or want these speakers to be, but for my money they delivered enough sound.

So, are they perfect? No... but they deliver enough sound and enough quality for your $40 bucks. And one thing is true, they are pretty cool looking!

I like these speakers.  There is a fair bit of distortion if you turn them up very loud, but they're good speakers.  As long as you're not planning on doing any serious booming, they get the job done.  I also like how compact they are.  They don't take up very much space on my desk, and the volume control has both an Aux and Headphone port.  It makes swapping to headphones when people are asleep really easy.

Small, but they are solid speakers. I have multiple devices and used to run audio cables everywhere. This resulted in a regular period of untangling. So, tired of the tangle, I did some research and ran across a ton of mediocre bluetooth solutions. Most were a single speaker and usually mono. But then I ran across the Dbest London speakers.

1. They are tiny and the bass is good for a 2 watt amp.  They are solid and seem to handle music, video, and games well.  And best of all, they are actually stereo. The right speaker is the master, the one with the on/off switch, the usb charging port, and the battery.

2. They are supposed to have a 20 hour use via bluetooth and 40 hours, if plugged directly into your computer, phone, or whatever. I've only had them for about 8 hours, so we'll see.

3. You can use them while they are charging, so all is well at that point. If you like portability, these are perfect. But if you want killer base, you need a stationary home sound system.

They are okay and sound good. But you may want something bigger after a while.

Bought this as a temporary solution after my roommate with full size Energy speakers moved out. They're ok for what they are (a set of bookshelf speakers with a small center and sub) but cannot compare with full size speakers or more robust surrounds.
If you are on a budget or have a small room these will work fine, and are almost definitely better than your TV's built in speakers. However, these failed to create as complete of a soundstage as my previous system. With these speakers I found it harder to identify where a sound was coming from, instead getting just a sense of in-front or behind. The surrounds (which are the same as L/R front) failed to ever catch me by surprise as the previous speaker setup had, and at times vocals were slightly hard to understand.
That's not to say that the listening experience was ever truly bad, but comparing these with the setup I'd had before, they were a definite step down).

I needed desktop speakers that were small but wanted to avoid the cheap awful quality sound that usually comes with a small size. I found it. So if you are crunched for space (office cubicle) and want some speakers that are pretty decent for the price (around $40); here you are. Not the bass you would get with an Altec Lansing subwoofer-but you really can't have that at an office anyway. Plus, you aren't paying out the $$$ a subwoofer would cost. A nice system for said niche.

They sound great, but if you like to listen to louder music and expect bass, these probably aren't the best option for you. They do produce more than enough bass for desktop setup. The problem is that since they only have one driver per speaker, each driver must make the bass, and keep the mids and highs sounding great too. When you turn these up louder, and you have bass hitting, it sounds as if these speakers are going up and down in volume. The reason is that the bass over rides the mids/highs, and you seem to have a loss of volume momentarily when you have heavy bass.

I'll be keeping these speakers, but probably getting a decent set of 2-way or 3-ways, and turn these into the rear channels for my computer setup.

I've had the same Advent speakers for 15+ years, on three different successive desktops. Since one was occasionally losing sound, I was pleased when Amazon offered me these Olasonic speakers to use and review. An added plus was that I was in the process of moving into a smaller apartment with fewer electric outlets, and these speakers are both small and USB-powered. I also found that they were easy to connect and set up.

My first reaction listening to them? They were not spectacular. For some reason or other, I thought they would outperform speakers from the 1990s, but then again a search online informed me that the Advent speakers I had were truly high quality. I also cannot make a fair comparison, since I had a subwoofer before, which I gave up because of limited space, and because I now live in a building where I cannot play music as loudly as I did in the past.

I was - and am - most bothered by the fact that these egg-shaped speakers keep tipping over, and have even fallen off my desk, leading me to fear an eventual Humpty Dumpty fatality  They are on my computer work desk where I constantly am shuffling papers and scanning books, and it only takes a tiny jolt for these them to roll off their stands. Their precarious position on separate stands also means that it is difficult to use them with my laptop while working on a laptop desk in bed unless they are placed on the floor. But then, simply moving a laptop or getting off the bed and jostling the laptop cord can cause them to fall off their stands and roll over. Not good.

Based on my above criticisms, you might assume that I am unhappy with these speakers. But actually my reaction is mixed. After a few weeks of relying on them while listening to streaming classical music while working, or to YouTube videos of many kinds (at the moment, The Doors, which certainly relies more on bass than do string quartets, I do find that the sound quality even in the bass compares favorably to my Advent speakers, and I do like their appearance, size, and USB-usage. Some reviewers have mentioned distortions at loud volume, vibrations and speaker movement with bass-heavy music, but so far I have not experienced any of these problems.

My inclination would be rate these speakers 3.5 if that were possible, but since my primary criticism is their lack of steadiness in upright positions rather than clarity of sound, I hereby elevate my rating to 4.0 rather than downgrade it. Computer users who want quality sound without spending more than $100 are not likely to be disappointed.

These are actually decent speakers for the price/size.  I like having a better stereo sound than that of a single speaker.  The only minor detail is that they are not very loud but a "good enough" loudness for most situations.  I use them in the office, kitchen, and bathroom and enough sound for my needs.  The rechargeable battery inside the speaker holds a charge for about the said stated hours.  They look as good in person as they do in the pictures on here.

Compact, sounds good, good price, just right for desktop speakers

When you're the proud owner of these, you'll never have to ask yourself, "What do $8 computer speakers sound like?"

These are just alright. Not great for music or video games, but decent for the occasional YouTube video or news report.

Nice little speakers that deliver great sound, easy to connect.

Disclaimer: I'm no audiophile, don't have a high-end setup, have no idea what I"m doing, etc. etc. In my opinion these are really really solid speakers at the price point. I have them set up at ear height, probably a little closer together than they should be. I tend to like a very balanced sound profile, and with these speakers I can definitely tell that the tweeters are small: the low end is slightly prominent. That said I'm very happy with the speakers.

They sound good "enough" (NOT as good as the A/D/S indoor speakers they replaced after lugging the A/D/S  speakers in and out over the last year). They DO require equalization.
  THE BUILT-IN WOOFER AND PASSIVE DRIVER DOES NOT ALLEVIATE THE NEED FOR A SUBWOOFER (although you will survive without one if necessary). Any reviews saying you don't need a subwoofer were by ppl who never owned a subwoofer.
  Also, they are pretty directional. So if you sit slightly off center, most of the sound will seem to come from the ONE speaker you are a little closer to. If you are away from the field of the speakers entirely, the highs will quickly drop off.
  The sound quality improves when you add a subwoofer with a crossover at about 100, limiting the amount of audio/bass the def techs have to handle. I use a Polk subwoofer with my own add-on casters and i just roll it out of the deck cabinet when needed. All connections have two-pole quick connectors (defaulted to "no sub"), so i can reconfigure with or without the OPTIONAL sub instantly. It all takes seconds.
  Also note: Although the speaker terminals take banana plugs, there is not enough clearance between the speaker cabinet and the mount to use straight plugs. I had to buy L-Shaped banana plugs and "trash" the straight ones.
  One more thing: I DO NOT like the fact that you CANNOT use these speakers WITHOUT the mounting brackets and you CANNOT stand them VERTICALLY due to the large and obtrusive bracket mounting areas on both ends. Some ppl (me, for example) DO NOT wish to mount these to the building.
  I have Def Tech SM55's in the living room (no sub needed), and SM65's in the theater and they're great (but also need equalization), but DEFINITIVE TECH really, really needs to rethink these outdoor speakers.

This is a good speaker for its price and size.

I was surprised by how small it was - I have a large palm and the speaker sits nicely on it. So portability is a given. Anker has
included a nice travel pouch as well.

I've experienced interruptions in the sound. I'm trying to verify if this is the Bluetooth itself or the speaker that's at fault.

The sound has good fidelity, especially given the size. I'm peeved when small speakers advertise "surround sound". The sound really does NOT "surround" the room, although the sound quality is crisp. This is due to the speaker size and design (square).

I am certainly disappointed with the bass. For all the glowing reviews and advertising, I expected far more.
I've compared this with other speakers (Bose, UE Boom) and there is a marked difference in the bass quality (and price too ;)).

I'd summarize the review as a "Good speaker for a fair price". You do get value for money, although if you're looking for the "ultimate sound quality", this may not be it!
