Short answer: both are discontinued, so this only matters if you are buying used. Used, the Sony SRS-XG500 is the better pick: it ranks #68 of 113 boombox speakers by sound quality (rated 3.0/5), against #106 (rated 2.1/5) for the Turtlebox Gen 2. If you want one new, the Sony ULT Field 7 replaces the Sony SRS-XG500 and is rated 3.2/5 at $448.
The Sony SRS-XG500 is the better-sounding, deeper-bass choice. A water resistant party speaker with a 30 hour battery, quick charging, and mic and guitar inputs. Its bass reaches about 49Hz before falling 10dB, against 65Hz for the Turtlebox Gen 2. It supports LDAC Bluetooth, which the Turtlebox Gen 2 lacks. It links with other speakers (Party Connect up to 100 speakers), which the Turtlebox Gen 2 cannot. Watch for: Thuddy upper bass, not as deep bass as others.
Why pick the Turtlebox Gen 2: A loud, waterproof and crushproof outdoor speaker with a big battery, device charging and stereo pairing. Watch for: Sounds basically identical to the original and the Turtlebox Gen 3: each generation mainly added features, not sound quality.
Buy the Sony SRS-XG500 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, buy the Sony ULT Field 7, which replaces the Sony SRS-XG500.
