It depends very much on the expectations!

I've read me long through many tests, reports and reviews and sets back and forth. What is there now in various speakers is the sheer madness. Unfortunately, this also a lot of unnecessary electronic waste is produced. Since I had excluded for environmental reasons, devices with fixed verbautem battery eventually came unfortunately only 3 units shortlisted. The Sony BTM8, the Creative D100 and this Easyacc Olive. All devices have the ability to change the battery! I find this very important, since you yourself know from experience with smartphones as quickly subsides the capacity of a battery. Therefore, I find that really should be banned by law, devices with fixed battery for sale. How many people throw then after 2 or 3 years the speaker in the trash! Something I did not want to join. Therefore, I decided spontaneously for Olive. He is to be used with me in the house, garden and when camping in the caravan. Therefore, the two competitor were out due to the size. But now to the device itself. I rate it 4 stars overall because it although for my purpose is good, but not a 5 star top unit. For this there this box is missing a call tone. One should not expect miracles here. It really does not sound like hi-fi sound, but rather by the old small boxes that you already could join in the '80s to his old Walkman, only that you can stop by the battery produce more volume than before! And you have to stop not connect more cables. Thus, the device is about to compare. When it is very loud, the music is consumed quickly. Also music of lower quality (eg Spotify without premium account) is not that great play at higher volumes. The speaker is in my opinion nothing for the following groups of people: Party people who want to use him as Partybox with high volume of people the real high-end sound need, lovers of classical music. The following customers will enjoy the speaker: Radio plays and podcast listeners, people who want to listen to music without headphones rather quiet without equal to sound for the whole neighborhood, people where it comes to a good price / Leistunsverhältnis and the environmental friendliness of the product.

Now again the points from my point of view summarized as follows:

Positives:
- Small, light, compact
- Good for the price processing
- Many audio source possible (AUX, USB, SD and Bluetooth)
- Bluetooth 4.0 (hence perhaps even in 5-10 years to use)
- Battery replaceable because not permanently installed. A good replacement or second battery costs about 6-7 EUR
- Looks visually appealing

Negatives:
- Play at high volume, poor quality or MP3 classical music only satisfactory (canned clang or distortion)
- Battery life with 4-7 hours depending on the volume and music compared to devices with fixed verbautem battery low
- Unit does not warn of low battery, but simply disconnects

I hope I could help other buyers with the rating. In conclusion: The olive is not a product that triggers enthusiasm, but no device in which you already regret buying when unpacking. I am pleased with this unit and it will hopefully have many years of enjoyment.
