A pair of era 300s or a pair of Five's for music?

End of lifespan? I’m not sure what that means for a Sonos speaker. So far, Sonos continues to support every speaker they have ever released. 

If you listen to Atmos music, go with the Era 300s. If you listen to stereo music, go with the Fives.

What I mean by end of lifespan is that a era 500 could likely be coming within the next year that would basically replace the five. It just seems the era 300s are more future proof. Just wondering is there such a huge gap between the 300 and a fives. 

The Fives are better for stereo audio and have better bass on their own.  If you plan on bonding a sub or mini sub, than the base factor won’t matter. I don’t think even the stereo factor matters much if you are in a smaller room.

Sonos has said nothing about an Era 500 and since it’s somewhat of a unique hypothetical product, we can’t say much about it’s introduction would mean about for the existing Five.  Given that the Fives are $500, and the Era 300s are $450, it stands to reason that an Era 500 may be priced somewhere significantly north of $500.  Possibly to the point where Sonos does think it makes sense to stop producing Fives.  And while an Era 500 would surely be better than for atmos and stereo than an Era 300, it may not be better for stereo than a Five.

That’s even assuming Sonos creates an Era 500.  They may feel like atmos music is better served by more smaller speakers playing together rather than 2 big speakers.  Or perhaps the Fives will have a place in atmos music and create upfiring only speakers to be placed in the front of a room along with Fives.

And when I say replace the Five I don’t necessarily mean by an era 500. It could be a new Five in itself and I would hate to fork out a $1000 for a pair of Fives that get replaced in a year. 
My apartment is 700 sq ft. My living room is small where the pair would be so I’m just wondering if era 300s would be great in a small space plus they are future proof. And what I mean by future prooof is if they make a new five I can buy them and move the era 300s to surround, which would be great. 
I just wonder if the era 300 could fill up my small living room area with music and also could I hear it pretty well from my bedroom which is extremely close. The arc doesn’t quite reach my bedroom the way I’d like it to for music. 

I would go with the Era 300s for that space, although I would include a sub mini.   I can’t say that it will reach your bedroom, as I don’t know your layout or what you personally feel is good enough.  If the Arc doesn’t reach your room, I sort of doubt that any speaker will.

Also, the Era 300s can be used as surrounds for the Arc, or Beam Gen 2 only.  There is no such thing as Fives in the front with any speaker as surrounds, currently.

My bedroom is wall is the other side of where my arc is. I can absolutely hear it and clearly just not as loud as I want it without having to turn it up super loud. I figure with the stereo pair of 300s or fives that wouldn’t be a problem. 
 

I know Fives can’t be surrounds. I’m meaning if a new Five releases I can just move the 300s as surrounds with my arc in the rear & put the new fuves in a stereo pair in front. 

1. I’m sure Fives can be surrounds;
2. You seem to have decided for yourself what you want.

Don‘t think too much… just listen. 😉

The Five is an amazing speaker and as it‘s part of the actual lineup it will be supported in future for a long time.

I have both here… and imho the Five for stereo music is quite better than the Era 300. 

lol no i absolutely havent made up my mind

I would not get 5s now. Too late in the product cycle to drop that kind of money. They only guarantee 5 years updates when they stop selling them. 
 

Or if you fomo too much buy both, return the loser.
