MZ-E10/N10 spec change!

I have no idea how anyone arrived at that 3-year figure... the life of the battery would vary a lot depending on how you use it.

Plus, the negative experiences I heard is that some peoples' Sonys break down soon after the 1-year warranty expires

...with proper care. an intelligent guy named leon

informed me that li-ion gumsticks (i don't know if there are technical differences on size, kind, etc.) are meant to have 300 (more or less) cycles and if you drain the battery fully, you've just completed one cycle. proper li-ion care like not draining it completely and recharging as often as you can will lengthen the life of your cell. cheers

What I don't get is...why not lithium ion polymer, if they're going with prebuilt in batteries? Sony used it once on the E95, and boy that player lasted an ungodly long amount of time on just the internal battery alone. I've read also that li-ion polymer batteries are quite shapable and moldable, which should've been ideal for the tiny E10.

It's very likely that the E10 battery is Lithium polymer anyway - it's very hard to imagine a metal casing for a 3mm thick Li-ion battery, and I haven't seen any examples either. A lot of cell phone-use Lithium polymer batteries were 4mm thick...

When Lithium polymer first came out as a technology, the problem with them is actually that their energy density is lower than the ordinary Li-ion, because of the "gel" electrolyte. Simply comparing dimensions (I did this a lot for my own fictitious designs), the 600/800mAh capacity of the last Sharp Li-ion batteries were insanely high compared to the Li-polymer cell phone batteries of the same era.

As for the E95... maybe Sony used a battery several times the physical size of a gumstick?

The extra thickness and the polymer "moldability" would allow them to do that, if they wanted to.

I'd say Sony made the battery choice just because gumsticks are way too thick for the occasion. Gumsticks already form quite a bulge on the recent players (E909, ST880, DS8), and the E10 is another 2-3mm thinner than those, comparing the thinnest points. On top of that, these players are 40-60g when empty, and putting in a 25g gumstick on one end means bad weight distribution.

I'll shut up now

Guys,
My Sharp MD-SS323 features the Li-ion battery, the same model with the MT821, and 831. At the moment (3 years old), it still have some juice left in them. So....I would say 2-3 years on the Li-on battery.

 

[myself, aka me]

It's hard to get a good weight distribution.. How about a large square battery

.

As for replacing the battery.. It looks simple enough. That battery door is stuck on with a screw.. Only trouble could be sourcing the battery.

I neeeedd E710 info

. It appears to be an E10 in different clothes, like the E900/700. (except no '5 direction control stick' )

back to batteries...

Based on what I've seen, I'd say the E710's amp isn't digital

However it does have the same EQ/surround features (don't let that minidisc.org 5-band typo bring you down).

 

[myself, aka me]

‚Ù‚ñ‚Æ‚¤?

I need to see what you've seen

Sony has hidden the E710 :\
I would get a 22800 yen DS8, but its remote is horrible looking, and I look at that far more often than the unit.. That 13.8mb catalogue lists the same specs as for the E10, except it's 'eco friendly' (uses some miniscule amount of non-polluting plastic

)

I want the EQ for my occasional 'turn the bass up full and the treble off' with an abnormally high volume

I don't really care if it's no improvement sound wise over the E900.. Kinda like V700s

(better for less: sharp vs sony)

 

[leon]

Well it might be worse than the E900?

What I've seen is simply that there's no "digital amp" in its product description anywhere, unlike the E10's description, which puts that in a very prominent place.

 

[myself, aka me]

Ahh.. What I saw on the PDFs and Sony sites was:
ahjklie jkl

I mean a big blur.
But I suppose it's digital amp though. Neither the E10 or E710 in the overseas model show anything that looks like digital amp. Sony's annoying me

 

[leon]

Sony's Japanese press release mentioned the E10 as having a digital amp, and mentioned no such thing for the N10. In business talk, Japanese or not, it's reasonable to assume that whatever you lack, you just don't emphasize... and if this is true, then they've got an amp they could put into the E710 and subsequent cheaper models.

 

[myself, aka me]

Is there even a press release for the E710.. ? Surely it can't suck so much that even SONY doesn't want to know it exists :|

Also, perhaps they're finally seperating the E7**/E9** series. The E707 was slightly different, but if the E10 has a digi amp and the E710 not... They're miles apart. The E710 is like an updated E909, but the E10 is new tech..

I'm happy with an updated 909, but a 22800 yen DS8 is sorta tempting..

I'll just hope that they have the same E909 amp in the E710 if it isn't digital.

 

[leon]

The E700 and E707 were important in the lineup, but didn't get press release either. Sony probably didn't think they need to put out a press release for the media to report on, like half of the other walkman (all cassette, virtually all of CD, memory stick and network when it's not a major update). I think this just shows how ubiquitous portable audio is.

Panasonic puts out more press releases, and Sharp does it for every MD portable, I'd say it's because they need more exposure, and think about the sheer power of the Sony brand

It seems that the new amps (with the EQ/surround) would all be 5+5mW, so don't insist on wanting the smaller-output E909 amp.. that was an emergency measure

 

[Tina]

5mW per channel on the e10 and n10? wow, finally sony came to their senses and didn't retain 3.5mW.
any idea what are the DC adapter voltage? n1 was 3v.

 

[leon]

In (grossly simplified!) theory, digital amps could offer double the output compared to analog counterparts, and still maintain compatibility with 3-conductor phones. So the DS8 for example, might consume closer to 2.5+2.5mW while giving us 5+5mW output. Sony could be using this to their advantage on the E10.

None of Sony's information indicates the AC adaptor output (only the input). My guess is that they'd use 4.5V, 5V or 6V (whatever Sony already produces) because of the Li-ion battery.
