From the first sight, it has some similarity (i mean the egg shape) with Sony Rolly SEP-50BT Dancing PMP. But it’s way different because XM-1 X-Mini Max II is a separable set of capsule speakers.
The both end of the speaker has a strong magnetic base to let them stick together tightly. It’s good in appearance and so-so in speakers sound output power and quality. XM-1 X-Mini Max II speakers offers only 2.5W x 2 with 80dB signal to noise ratio. But it’s pretty cool since you can use it for up to 12 hours continuous playtime.
