  • I been using Siemens for more than 9 years. My first phone was Siemens. What I like about this phone is the durability and quality. I have my EF51 for almost 3years now and anything that you can think to ruined this phone was already experienced by my phone. I always drop my phone bcoz of clumsiness. The worst was when it slipped on my hand while im at the terrace of our house at the 2nd flr it fall on the street from more than 10ft height. I was so horrified but I found out it still intact and in good condition. Another is when I drop it on the water and actually it was soak in wet. So what i did is i just clean in it up and dried up the parts and then back to normal again. And now I have my new phone but its still Benq-siemens. It's CL71 and I still have my EF51.

  • and it has a very good price. In Romania the best price with no contract is ~85 euro. (I bought it over the internet nad the price reffers to this kind of price)

  • after 2 month -stand by batery 4 days -9 hours of mp3 +10 min of talk, with the mp3 player minimized. (!!! its important to minimize mp3 player to save batery) - simple menu, but i don't like how the menu looks. -very interesting futures like : voice dialing(dial a number) posibility to record radio posibility to connect bloototh setero speaker a lot o f camera options(ex face morf, lots of effects) if the manual is read u will find a lot of futures. Menu voice commands. Annoing - cand record/play movies - the face ca-nt be changed About the headset- it suports stereo bluetooth. And with wire u can connect mini usb, it is compatible with other model of phones. About the look, it is a girly phone.

  • this is really not worth the price ... and the camera is not that good

  • buty and smate sealphon

  • is true if this camera is not good??

  • After a month: bad: week batery poor signal low quality camera good: good and simple to use mp3 player resistant fast data transfer cable/ bluetooth (at lest much faster than moto v360) best price for its quality

  • What a hell is this?! This ain't no phone! It looks like a Creative mp3 player to me... Nice features though..

  • By far the worst phone I've ever had!! It is SLOW. The network keeps disappering - and won't go on again until you search for it yourself. The sound is really bad and there's some bad feedback! Don'y buy this!!!

  • I'll say the same thing for n91 too. The mp3 player is awesome and stuff.. But the phone on a whole is slow! People buy n91 for the mp3 player,this phone too People are not gonna use the camera The n91 has niether flash nor autofocus and nokia makes some of the best camera phones

  • Very true, If Ben-q is gonna make this a music phone then throw away the camera.Its a music phone ppl. It should have 1g internal memory instead of a camera...Its not even that good!

  • Hi, is there anyone knows about this phones record function? What is the bitrate of mp3 recording from radio and could we adjust the record quality?

  • how long last the battery if it play non-stop mp3?

  • Hello. I am having a problem with the mini SD. I bought a mini SD and downloaded mp3 from my computer and saved in the mini SD. Now, I inserted it in the card slot of my phone successfully but when I am checking the memory status it daid (Not Existed). Also, How can I play the music from my mini SD in my phone? Your help will be appreciated.

  • it supports 1GB cards

  • would someone tell me, does it support video and 3gp files? thx

  • Hi Friends,I have 2 questions about this phone: 1.does it support 1 GB Card? 2.Has it any limitation in recording voice? thank u!!!

  • Hi, I Have 2 Questions About This Phone,PlZ Help Me! 1.Can This Phone support 1 GB Memory Card? 2.Has This Phone Any Limitation In Recording Voice? Thx a Lot!!....

  • This is music phone.

  • I heard that e61 has fm Radio recording (aac support) as like as N gage Clasic? itsn true?

  • thank you a lot, hendry!! i don't want a very expensive cell phone that calls attention... i'm afraid that someone steals it. otherwise, i want a good phone (of course). so, i won't need to buy a new one so soon. i think i'll buy the s88.

  • dear Ninha, I,am Hendry from Indonesia ,all U,r questions about this cellphone the answer is yes the cellphone haved that features. see You,

  • I thing the cellphone is not bad and the batterey up to 4 hours when U talk

  • please, could someone help me?! :D i live in brazil. this cellphone isn't sold here but i have a friend in the usa, i think he can buy it for me. but, before i ask him to do that, i have some questions... does the battery last long (how many hours aprox.)? does it play 3gp videos? does its camera have flash? does it support games like the sims 2 (there's a version for sony ericsson cellphones, i was wondering if it's compatible with this one)? thanxx a lot!! :D

  • It seems like a good mobile phone, though as a MP3 phone it doesn't have enough internal memory and there is no memory card included in the package which is a pitty. Also when Nokia, Sony ericsson, Motorola, samsung,... are talking about their 2 and 3 mega pixle camera in their mobile phones, I don't understand what is 1.3 Mpixle camera would say in competition. I think people in BenQ-Siemens should reconisder in some of the features they put in this phone, just look at sony-ericsson's walkman seies or Nokia N91 at the top of the mountain and see what this mobile phone has to offer

  • Yes you can set almost all except SMS tones. MP3 can set as ringtone, caller id ringtone and alarm. Call id function can be customised. Wallpaper can be set as gif and caller id as well. The picture output (1.3 mega pixel) is so so, but what do you expect from a cheap music function phone. :)

  • hello all, Could anyone tell me 'bout its picture capability? is it good enough? And can i use pix, music files on memory card to set wallpapers, ringtones,caller id? Does it have caller id by pictures? Can i set another music file for message& alarm. because i have E61-comes from BenQ-Siemens also, and it does not let me do that! A bit silly:(

  • It's not like iPod it's like Creative mp3 product.

  • I got this phone and it is so cute and funky looking. The music implementation is good and too bad it does not support ID tag. It does not sort album, artiste and music genre. Anyway, it does support playlist and shuffle function. The stereo sound is good enough though from the speaker (is loud) and thru bundle stereo headphones.

  • this one looks good.but i prefer a black one. i've been waiting it for a long time.anyone knows that when it will be release in viet nam? and how much does it cost(approx.)? please answer...

  • My god, what is it with you people and your obsession of doing crapy iPod-imitating things; admit it, nothing is best in usability than the iPod

  • Dis fone looks cool and cute!

  • This phone can be played without stereo ear piece. The sound produce from the speakers is mavelous and in stereo sound as well. The cute form factor with the innovative keypad is really a design of its own. But too bad that the inside keypad buttons are a bit too small. - Supereb sound quaility - Support Bluetooth stereo headset (A2DP) - Can record radio into mp3 file - Speech to music (silly function)

  • one question... do the MP3 player would sound in freehands? Is possible to listening it without earpieces? Do the music sounds high? sorry for my english... I'm Spanish xDD

  • This awesome! Cant handle sress without music, then this is the kind of fone yo need.The fone is just too cool and cute for those wanna be noticed..........

  • My friends this is a great stuff to own.Its more of a juke box than a phone to those who love music. Try it and experience the fun in it....

  • one word to describe.... cute!!!!

  • you know guys you can listen to music without havin a sim card in the phone Absolutly MP3 Player

  • you havent seen this mobile untill you have heraed the music coming out of its speaker AMAZING loud music comig out of this tiny so call phone music with lyrics , radio and even radio recording its an mp3 player with a phone not the opposite

  • Just what I've been looking for

  • Freakin' awesome phone man. Best Regards JED

  • When U flip down the music control bit, u will see the keypad... it is about the size of an i-river and is quite cute. =)

  • my GOD wut the hell is that,is it just like a casio's calculator?

  • I've been tot the presentation of benq-siemens and this phone looks amazing, it wil cost aroudn 249 euro in belgium nice price nice phone

  • What the hell is this ?? true or not ... :(

  • oh, dear.my godness. don�t tell me that this is a phone, it�s a gameboy. please, be serious.

  • this phone looks just like the creative zen micro mp3 player. despite this fact this is an amazing looking handset and i look forward to seeing it

  • iz dis a mob?? if it is..iz dis a fungus shaped mob???

  • so the design not interest to buy, give it with new color body, example red,black,orange,purple because to much line in body

  • The BenQ Siemenspod

  • 120x128 screen!? thats way waaay too tiny

  • ok!not the best phone forever but i think it's really nice phone,

  • Things seldom seen are strange.

  • the best phone forever

  • Not the best phone I've ever seen...Ugly la

  • this is the best phone I've seen!!!!!!!!!

  • this is the ugliest phone I've seen!!!!!!!!!

  • Bring Enjoyment N Quality!! hehe

  • looks nice to me! Benq designs mobile better than siemens, no matter in apperance or the specifications

  • It does have A2DP! Yeah!

  • yes bluetooth!!!!!ole ole ole

  • maybe have A2DP

  • It has bluetooth i'm 100% sure. I saw the specs on benq offecial site.

  • this phone is good +20mb +sd slot +256k TFT display +FM radio 3D sound +mp3 and good resolution camera -poor resolution of display -no bluetooth no IR

  • benQ siemens ef51 great design but they made have made colorful design something like sony ericsson w800i n how come no blue tooth hmm

  • ...It reminds me of creative zen micro somehow. :-). Or maybe an ipod...

  • This reminds me of Xelibri - Cheap, Over the top prices and discontinued, its a phone with media player functionalities

  • reminds me of a creative zen

  • The design reminds me of Siemens SX1.

  • What iz this device ?? Phone wid Media plyr or Media player wid a bit of fon facilitiz ??

  • please let siemens take the lead

  • This phone looks Ugly and Odd compared to the leaked design of upcoming BenQ-Siemens series. this gotta be a Ben-Q design. They should take this off.

  • really good,another ipod fone...

  • Hey!!! What is this thing?

  • Whats happened to the siemens touch? This is absolutely appauling!

  • It DOES have Bluetooth. In fact, it even supports Bluetooth stereo! This is a great niche product. It's an almost perfect music phone except for the low-res display.

  • This is really ugly. At least the other models are better.

  • look nice to me :)

  • No, no, no - designers of siemens are better then benQ. This is not a really siemens, this is a stupid BenQ!!!!!!!!!

  • but i think it has a cool design and i like it!think different

  • i think this design is pretty awesome. itd appeal to a lot of people in my area. i'd get it if the screen was bigger. but the voice search through song names is cool.

  • I didn't like the design. And I'm wondering why there is know bluetooth?!

  • Don't know how this phone looks in real, but from picture it looks UGLY. At first I thought its a slider but well..hmm nice to see a different flip mechanism.
