Mini Speakers comparison

When I was in February 2015 in accordance with a transportable speaker for my phone, I realized that the search took much longer to complete than intended. To help other people with the same problem, thus saving them time, I decided to submit the following report.

About me:
I (38J, m) am an absolute amateur in the field of Audio & HiFi and thus also in the area of ​​speakers. Therefore, I ask for your understanding that I try to avoid technical terms that I myself do not understand. Should I still use technical terms wrong, I beg your indulgence.
I do not know how well a speaker can sound at a certain size and a certain price / needs. Since I could not make a final judgment from the present me test reports and customer reviews, I ordered in February 2015 six different Speaker at Amazon, for comparison.

This comparison and the descriptions of the speakers are purely subjective and have not the goal of completeness! Acoustic perception often seems to be very subjective: what is a good for the sound, can be from another less well perceived as. Otherwise I can not explain many customer reviews. When in doubt, therefore everyone should give themselves an impression.

My criteria in the selection of speakers:
* Small, compact speakers, which one could easily carry in your pocket
* Usage: gain of mobile phones with music playback (currently Samsung)
* Good and clear sound without clattering, at medium to high volume
* Suitable order an otherwise quiet (without noise) space of max. To provide sound 100 m³
* Price: max. 50

My test instruments:
* My Samsung phone
* My favorite songs (that I can better compare the speakers to each other genres:. Rock, metal, ballads, pop)

Test Setting:
* Quiet room
* Loudspeaker maximum volume; adjusting the speaker volume (medium to loud) then took the phone (my opinion: if speaker manufacturers provide volume, then this should also sound good)
* In a knockout method I have always compared two speakers to each other, the better was further tested, the worse was eliminated. The only criterion here was the sound quality!
* All speakers have been tested exclusively with the Bluetooth connection

- The loudspeaker volume level can only be guessed (no signal that maximum volume is set.)
- Sound distortion and overdrive at high volume (the bass is not bad)
- Medium level already very low

RAIKKO BASS DISC
Positives:
+ Volume and playback pause button on the unit
+ Loop with snap hook

- Its commitment to speakers on a table, the sound will again significantly worse
(The stability of the Bluetooth connection, no statement can be made, because the speaker was eliminated very rapidly)
Winner Round 1: Grundig GSB 110 (sounds a little better, although still far too poor for my needs)

***********************************************************************************************************************************************************************

Round 3: Logitech X100 vs. Rapoo 12959 A300

A direct comparison of Rapoo sounds much worse. The bass can only be guessed. In order for this round was already finished. (For me, there is therefore no reason nor anything to write about Rapoo!)
Winner Round 3: Logitech X100

***********************************************************************************************************************************************************************

Round 4: Logitech X100 vs. TOSHIBA TY-SP1

The speaker of Toshiba rattles and distorted at maximum volume, making it worse than the Logitech. (For me, there is therefore no reason nor anything about the Toshiba to write!)

Round 5: Logitech X100 vs. JBL Clip

JBL Clip
Positives:
+ Very loud (louder than the X100) and still with good sound quality (the highs are better and more clearly illustrated than in the X100, but the clip sounds but then was not crowded)
+ Handy and carabiner to hang the speaker
+ Sounds lying and hanging well
+ Jack sent accommodated in the housing (but has a drawback see negative)
+ Beep when switching on and off
To connect + jack output to the speaker with other speakers (pairing)
+ Casing made of plastic and metal (affects more stable than the X100)
Negatives:
- The cable of the jack plug is firmly connected to the speakers, so it is not replaceable.
- Only the volume is adjusted to the speaker. Titelwiedergabe-, or stop button does not exist.
- The loudspeaker volume level can only be guessed (no signal that maximum volume is set.)
Winners Round 5 and thus overall winner: Very briefly, wins the JBL clip before Logitech X100.

CONCLUSION:
The decision really was very difficult for me. Both are very good (in comparison to the other tested speakers) speakers. The X100 will appear in the sound a bit fuller and the bass is stronger. The clip, however, is a little louder and clearer from playing heights. Here I can only recommend, to gain an impression and to compare the two speakers themselves. Depending on musical tastes and use the decision could also turn out in favor of the X100.
