SRS-XE200

I habe 2 xb33 and ahve listentend to XE200/300 also. The xe200 is just meh. The xb33 has a quite warm and natural sound, it never gets harsh and always sound nicely mellow and rich (also voice come over great), but highs are underrepresented so it not as crisp and open and detailed sounding. The XE300 is a bit too large for what it is, is slightly deepe rin bass, but doesnt soundans nice and natural. both the xe300 and xb33 are very durable and have good battery life. The motion plus is more crisp and detailed than the Sony models, but it can get harsh on higher volumes. The sonys work better in stereo or party pairing mode. All speakers mentioned are older models so I guess you are looking fur 2nd hand or refurbished models?
