Sound Quality : Boat Stone 650 vs Nakamichi Speck vs Boat Stone 200
This is review is primarily focused on sound quality.The term Bass is used losely. One doesn’t expect true Bass from such small drivers.SHORTER VERSION:Boat Stone 650: Very loud. Loud and somewhat uneven bass. Mids are a bit supressed. Somewhat muffled midrange. Decent treble. A loud bassy speaker.Nakamichi Speck: Barely louder than the 3W Stone 200. Mids clearer than 650. Bass much much lower than 650. If looking for VFM rule this one out, unless this is on a big discount and others aren’t. Overall fairly even sound, at a questionable price and volume.Boat 200: More bass than expected of a tiny 3W speaker, but lesser than Speck, and way lesser than 650. Excellent midrange and terble. Much lounder than what you may expect of a 3W speaker. Amazing speaker in a tiny package, with insufficent bass.LONGER VERSION:I have had the 200 for years and many have asked me to order it for them. It is an excellent tiny satisfying package. The midrange, vocals and treble is excellent, and matches speakers several times it price. If bass is not what you are after, you are unlikely to find a better package even at a much higher price point, especially if you care for even sound.(By Even Sound, I mean all relevant frequencies produced fairly well – no major suppression or enhancement)I checked the others as I usually hear music on a semi-pro system, and the insufficent bass (lower-mids) bothered me.Nakamichi USED to be a Japanese company making very high end tape decks in the 90s so the benchmarks were high (now it is a China based company). The 25W raised expectations further. As said, it is barely louder than the 3W Stone 200. It is fairly even sound, but not a significant enough improvement in bass over the 200. If you don’t care about the money, and want something better, than the 200 with even sound, this could be it. The mids and terble, are a tiny bit better in the 200. Speck also has a larger battery, giving substantially longer backup, and better water protection (useful if you use yours in the smallest room of the house 🙂 )The Stone 650 is miles ahead in bass and loudness. if that is what you care for, amongst the 3 – your choice is simple. The bass is uneven, however. All three speakers have memberanes in the inner shell acting as passive bass radiators. One should not expect much nuance in bass from those. If a thump is what you care for – yes it is certainly there (for the size). With somewhat uncontrolled bass, the midrange is compromised – somewhat suppressed and somewhat muffled. No, it is not major, and many mgiht not even really notice it much. The transiton between mid and lower-mids/bass isn’t great. One usually doesn’t expect as much from such speakers, but the Boat Stone 200 set the bar high – very high.Keep the boat stone at an angle such that the drivers (speaker) are in the direction of your ears. It makes the midrange a bit better. Reduces the bass a bit, but makes the sound more even. Tough it is impractical to keep it so, it makes the sound a lot closer to what I desire.SOME EXTRAS:Placement of these speakers makes a big difference. Keep them about 6″ away from a wall (ideally a corner) for enhanced bass and fuller sound.If you look at teardown videos, you’ll notice that the 650 has much bigger magnets than the others. It is a heavy speaker. I like that, since it keeps it stable and the rubber on the side helps further. It is well designed, except the + and – volume buttons should have been interchanged for intuitive use.The 650 can also be placed vertically. That too changes the sound. Lesser bass, and possibly a bit clearer on the whole (reduced bass = less intrusion into the mids, in such speakers)Speaker characterics change subtly over 100 odd hours of use. Often quite prominent in the first hour, so do not form an opnion before running them in for about an hour.Conclusion:Nakamichi Speck: More even sound than the other two, not at all as loud as expected, better waterprof rating, bigger battery, high priced, despite Chinese – Buy if you don’t care for the money, volume and are okay wihtout much bass.Boat Stone 200: it is a star! Excellent even sound, however the lack of bass as compared to the others pulls it back. If you are on a budget, or if you don’t care much for bass (especially for lectures/documentaries or vocal music) this is brilliant. I have used it for long.Boat 650: Heavy. Loud. Lots of bass. If you can deal with the somewhat (and it is not big) unevenness and slightly muffled sound – it is a good package.For my needs, I added the 650 to my equipment list, while keeping the 200.PS: This was my way of giving back to the community for the numerous reviews I have gained from.

Boat Stone is really awesome product and quality is too good
Sound quality is really good and listening music from gaana.com from this device is really soothing. very reasonable price wise. Cant expect much from this much price

Battery
I have been using it for 2 years now and the speakers are not working properly after 2yrs of not so regular use. Sound quality was good battery was good aswell but should have lasted more for 2k

Good quality However Not Loud, Lack Bass Punch
Nice looking lot of stickers in box, sturdy packaging but speaker miss in loudness it’s clear in vocals however Bass is missing treable okish. Good for falk music, average for everything else, I am dissapointed.
