Summary: I got a set of XBA-3s a few months ago and I liked them a lot, but I had been wary with them because of the somewhat steep price. Then I found at a local audio-store super discounted XBA-1s and I though those would be a really nice gift for my friend who still used crappy earbuds. I got them but I was very curious about how they sounded so I ended up opening them and what a pleasant surprise that was.
Pros: Extremely clear sound for less tha $100, Small and comfortable, semi-flat cord, super lightweight, Accesory set
Cons: No strain relief, thin cord, don't isolate that much noise, not bassy
Summary: Along with the summary below, I have posted a Youtube review of the Sony XBA-1. If you like the video, please check out my channel for more reviews
The XBA-1 is very practically designed, with a narrow nozzle and a thoughtful selection of tip sizes with Sony's great hybrid tips. They are very lightweight and feel comfortable in the ear, but because they stick out they are not suitable for sleeping on your side with.
Pros: Good wearing comfort, lightweight, isolating, mellow sound signature with clear mids
Cons: Blunted bass and treble, grain to the sound, not everyone likes J-cables
Summary: These earphones are massively comfortable and clarity and soundstage is amazing for its price (but im not a total expert on IEM's so maybe there's something better out there). Best used for people that want clarity and listens to rock, acoustic, EDM, classical, live etc for the best experience. Not that great to those who love dubstep, etc.
Bass goes a bit muffled at first, but becomes more clear after burn-out. Burn out time is around 1-2 days.
Pros: Good Soundstage, Extremely Comfortable, Clarity is amazing for its price
Cons: Bass goes deep but a bit muffled, needs long burn out for full experience.
Summary: I've always been a Sony earbud fan. They seem to sound the best at the price point. Well some how I lost my 2 year old $39.00 Sony in ear monitors a month ago, and it came down to this or some way more expensive bose that still didn't even sound as good as these. So glad I picked them up.
Pros: Sound Quality. Highs, Mids, and Lows play clear as a bell. Light weight material.
