Short answer: the Ultimate Ears Everboom for better sound quality, the W-King T9 for the lower price. The Ultimate Ears Everboom ranks #32 of 77 large speakers at $149.99. The W-King T9 ranks #38 at $130, $19.99 cheaper.
What the Ultimate Ears Everboom offers: This speaker may move around as we get better sound samples Watch for: Has an upper bass boost and is tuned warm with rolled off treble. Not very deep bass.
What the W-King T9 offers: 80W output power, 106dB max volume, 24-hour battery life, power bank function, Bluetooth 5.3 with 100ft range, TWS stereo pairing with wireless microphone, dual subwoofers, RGB lighting, MicroSD and AUX support, USB-C charging, karaoke capability Watch for: Peaks in the upper mids which makes it sound a bit harsh.
Buy the Ultimate Ears Everboom when sound quality outweighs the price for you, and the W-King T9 when the price outweighs sound quality instead.
If water resistance matters to you, the Ultimate Ears Everboom at IP67 (brief submersion) holds up far better than the W-King T9 at no water resistance.
