|Speakerphone test||Voice, dB||Ringing ||Overall score|
|Apple iPhone 5||66.8||66.1||67.7||Below Average|
|Nokia Lumia 920||61.6||64.8||65.8|
|Samsung I9505 Galaxy S4||70.6||66.2||77.3|
This means you'll be able to hear the Nokia 515 ring even if you're in a loud environment. Its ringing sound will get to you even if you've been covered it with a pile of stuff or put it in a large purse.
With no resistance applied to its line-out (when used with an active external amplifier), the Nokia 515 does decently well, achieving some good scores and garnishing them with about average volume levels.
Plugging in a pair of headphones leads to a rather large spike in intermodulation distortion and a moderate one in stereo crosstalk as well as a rather big drop in volume levels. Overall, the low-standing 515 does well, but it won't get any audiophiles excited.
