Sony's SRS speaker lineup covers three different jobs in one range: compact EXTRA BASS speakers for everyday carry, ULT FIELD speakers built around Sony's bass-forward ULT POWER SOUND platform, and X-Series party speakers designed for karaoke nights and outdoor gatherings. All ten models are in stock in Nairobi with same-day delivery, so the choice comes down to how loud you need to go and how much bass you want to carry.
Which Sony speaker should you buy?
Everyday & travel (from KES 9,000): the SRS-XB100 and SRS-XB23 are compact EXTRA BASS speakers you can sling in a bag, ideal for a desk, a dorm room, or a day trip.
Outdoor EXTRA BASS (from KES 18,000): the SRS-XB33 and SRS-XB43 step up to bigger drivers and longer battery life, both IP67 rated for the beach, the pool, or the boot of a car.
ULT Power Sound (from KES 13,000): the ULT FIELD 1, 3, and 5 use Sony's dedicated ULT button to punch up the bass on demand, with battery life climbing to 25 hours on the FIELD 5.
Party & karaoke (from KES 43,000): the SRS-XP500, SRS-XG500, and SRS-XP700 are the biggest speakers in the lineup, with karaoke mic inputs, party lighting, and up to 30 hours of battery life on the XG500.

Frequently Asked Questions
What is the difference between the XB series and the ULT FIELD series?
The XB series is Sony's long-running EXTRA BASS lineup built for portability, while ULT FIELD speakers use Sony's newer ULT POWER SOUND platform with a dedicated ULT button for an extra bass boost and generally longer battery life.
Which Sony speaker is best for a party in Nairobi?
The SRS-XG500, SRS-XP500, and SRS-XP700 are built for parties, with karaoke mic inputs, party lighting, and enough output to fill a compound or event space.
Are these speakers waterproof?
Most of the XB and ULT FIELD models carry an IP66 or IP67 rating for dust and water resistance, while the XP500 and XP700 party speakers are IPX4 splash resistant rather than fully waterproof, so keep them undercover in heavy rain.
Can I use these speakers indoors and outdoors?
Yes. All ten models are wireless and battery powered, so they work equally well as a living room speaker or taken along to outdoor gatherings, though the party speakers (XG500, XP500, XP700) are heavier and better suited to a fixed spot for the evening.
Can two Sony SRS speakers be paired together for bigger sound?
Sony's SRS-XB, ULT FIELD, and X-Series speakers generally support stereo pairing or party connect with other compatible Sony speakers, letting you link multiple units together. Check the individual product page for pairing details on each model.
