Short answer: the JBL Partybox On the Go, if you are buying new. The Aiwa Exos-9 ranks higher than it (#9 vs #60 of 91 boombox speakers, 4.2/5 vs 3.0/5) but is discontinued, so only consider it used; the JBL Partybox On the Go is still sold new at $300.
The Aiwa Exos-9 is the better-sounding, deeper-bass choice. It still sounds great against current models. Its bass reaches about 44Hz before falling 10dB, against 49Hz for the JBL Partybox On the Go. It is rated for 10 hours of battery against 6 for the JBL Partybox On the Go. It has an adjustable EQ, which the JBL Partybox On the Go lacks.
The JBL Partybox On the Go is the tougher option. A wireless microphone is included. It is rated IPX4, while the Aiwa Exos-9 has no water resistance. The tradeoff: Battery life is short, and its sound trails the rest of the Partybox line.
Buy the JBL Partybox On the Go if you want one new; the Aiwa Exos-9 is discontinued, so only look for it used.
