I WAS ON A JOURNEY TO GET CLEAR SOUND WITHOUT CHANGING OUT ORIGINAL RADIO IN MY 1980S PORSCHE ... AFTER TRYING COUNTLESS OTHER TAPE TO AUX OPTIONS, I HAD ALMOST GIVEN UP AND IN TO A FUGLY MODERN RADIO DECK.... THEN I GO THIS AND IT WORKS... IT KEEPS ON WORKING ... THE CORD IS SOLID AND CONNECTOR IS SOLID .... IT IS SO MUCH BETTER MADE THEN THE OTHER CRAP YOU'LL SEE AT WAL-MART OR ON HERE .... ..THIS IS A NO BRAINER

Habe diesen Adapter im Kassettenfach vom Autoradio. Mit dem entsprechenden Zubehör spiele ich die Musik vom Mobile / Handy über die Autolautsprecher ab.

Sound quality is far superior to the terrible fidelity on my Bluetooth FM/Transmitter, crisp highs and deep lows. Works well with my tape deck, I assume cheaper decks might be more problematic. The cord could be a bit more robust but the length is good. In general I am very happy with the purchase and it is finally a pleasure to listen to my devices through my car stereo.

Sirve muy bien y es super útil si no tienes bluetooth en el coche! Lo recomiendo mucho, ademas de que llega rápido!

Overview:The CPA-9C shows quality engineering and workmanship, despite its manufacturing takes place in China. I cannot verify the longevity of the device [for now], but it does seem rather sturdy compared to other models in the same price range ($12-16). As for sound quality, this particular cassette is very sensitive to the actual amplification power of your audio device. Lower quality DAC's will perform very poorly with this cassette, however, even with a poor audio device, the sound quality transmitted through the cassette is consistent with the actual quality that the device itself is capable of producing. There is virtually no hissing or cassette noise while in operation. The only flaw this device suffers is the poor transmission of lower end frequencies - they are nearly omitted from playback on any audio device.Control for Confounds (overkill for most people):I bought the CPA-9C for use with a 1997 Lincoln Towncar (fleet edition), a 2009 Grand Marquis Ultimate Edition, and a 2010 Crown Victoria, all with the cassette player option in the radio. I used three audio devices with the CPA-9C, ranking with the best playback first: a 256 GB custom 5.5th generation iPod Video (60GB model), an iPhone SE, and a 16GB 5th generation iPod Nano. All devices had no EQ enabled. I used three music files in AIFF format (actually fully lossless & 100% CD quality): Lindsey Webster's Back to Your Heart, Metallica's Unforgiven II, and Justin Timberlake's Strawberry Bubblegum.As with many 3.5mm female ports, they gather debris over a period of time, so I cleaned each device of any lint or debris (as this effects sound quality in any listening medium). I took this step because in my experience with various Phillips and Belkin cassette adapters that utilize a 3.5mm jack, there is always an evident hissing noise, sometimes from a poor quality connection at the audio device itself. I felt that many reviews didn't specify that they controlled for this, so I thought I would mention it in my review. I utilized two separate listening systems to verify that the 3.5 mm ports of each device were consistent - a VSX90 AVR in 5.1 and a UE Boom 2. It was overwhelmingly apparent which devices had a better DAC when using the VSX90, even though the same file was played on all three devices.The Actual Review:In each car, the CPA-9C performed exceptionally well, beyond any other cassettes, namely Belkin, Phillips, & Monster. Each car was set to 20% volume on the radio. In all cars, the CPA-9C performed the same each time, each in different temperatures (20F, 45F, 75F). Initially, it took me some time to figure the optimal volume setting for each device - as each has a slightly different output current, and hence, the volume output to the cassette was also different. I found with a higher quality DAC (the best being the custom iPod 5.5th), the sensitivity for volume was also greater. The iPod nano had poor quality and low volume, even when the device was set to full volume, whereas the iPod Video was perfectly content at roughly 50-65% of full volume (in fact, beyond 65%, audio clipping began to occur because the signal was too much for the cassette). The iPhone SE found its highest quality of sound and volume at around 80%.Each file played well, but there was a noticeable deficit in the lower frequencies. I can only verify this with the 09 & 10 cars, because they also have a CD player (which is how I was able to compare the actual CD track to the same track on each audio device using the CPA-9C). I feel as if this may not be the fault of the CPA-9C though, because the medium of using a tape is lossy - mechanisms in the cassette and cassette player transmit the sound, as opposed to a laser for a CD. There is no hissing as there is with the Phillips and the Belkin, and the quality of the 3.5 mm end is far better than that of the Monster. I believe if you are wanting the best audio quality and all you have is a cassette player in your car, the CPA-9C is the one to buy.Final Remarks:From my experience with these cassette adapters (the CPA-9C among others), I learned that the DAC from the source audio device plays a LARGE role in the actual quality that can be transmitted through the cassette to the stereo system in your car. I had an intuition that it would make a difference, but I hadn't realized how much of a difference. If you decide to purchase the CPA-9C, the biggest variable that will influence the sound quality is the source device- not the car, not the cassette player, not the temperature, and not even the file quality used for playback (of course you will hear differences between mp3 and AIFF/WAV).My best advice to consumers on cassette adapters is this: The CPA-9C is the BEST cassette adapter on the market.If sound quality is your goal and money is tight, look for a used 5th gen or 5.5th gen iPod video on Amazon. $60-70 is well worth the investment when a quality new radio from Sony or Pioneer costs $500-750. You can load your music up (provided you actually own your own music and not a streaming service) and just go - no strings attached. They are incredibly reliable and are making a surprising comeback in the market. All iPods' value is going up, despite introductions of the new iPhone X and other 'super' devices. Many sellers on Amazon can get you in around $60 if you look around.If convenience is your goal and you only want to use your smartphone, check your volume levels to ensure you aren't clipping audio. I'd also recommend setting your EQ to 'off' on the source device so you can tune your car's EQ instead. You'll sparing the cassette player of extra work and the sound quality will be much cleaner and crisper.Lastly, do not believe that a cassette adapter will surpass a CD player. If you want the best quality you can get, it all starts with your source audio device - the quality of the DAC and power of its amplifier. Any cassette player is limited by the mechanisms that dictate its operation - but the Sony CPA-9C will get as close to lossless transmission from your device as possible.

音質とか良く分かりませんが、FMトランスミッターの時に比べて快適になりました。

I was surprised this tape had such good reviews. I have filed through probably over 10 different tape deck adapters such as this one and this is probably one of the worst I have had.-Cord is extremely thin. This will eventually cause the cord to break or wear thin at the connections. Being in a car you unplug it, plug it in, cord is on the floor, passed around etc. It's just not built for durability.-It picks up A TON of interference from other electronics. I think it's any time my phone is transferring internet data (whole time playing Pandora), or maybe its my radar detector. Either way I cannot get through a single song without hearing obnoxious buzzing noises making the tape utterly useless.-Makes a clicking noise, but this could my tape deck in my 2004 acura tl. Not sure, I know I've heard this before with other tapes, some less - some more.Overall I cannot use this tap adapter and am disappointed in the other reviews. Maybe others will have a better experience but I cannot listen to this thing buzz any longer and I've owned it for two days. Of all the electronics technology this is such an outdated product, being unchanged since the CD was invented, and one that I use everyday and am in a constant struggle to find one that lasts, and sounds good at the same time. They are almost all junk.

J'ai préféré mettre le prix tout de suite. J'ai lu les commentaires de celui ci (http://www.amazon.fr/SONY-CPA-9-Adaptateur-Cassette-Automobile/dp/B00007EDLW/ref=pd_sim_sbs_ce_1?ie=UTF8&refRID=1G3JXJRY45G8806AT93W)C'est un excellent produit qui coûte une dizaine d'euros plus cher mais qui fonctionne parfaitement et c'est ce qu'on lui demande. Très bonne qualité de son. Aucun souffle ou bruit parasite. C'est mieux que si j'écoutais la radio.La cassette dispose d'une encoche au niveau du fil pour le préserver (Vous comprendrez quand vous l'aurez). Dans l'ensemble cela a l'air solide.Je le conseille vivement car j'ai acheter du premier coup et je ne suis pas déçu. Je ne voulait pas perdre mon temps avec des produits moins cher mais défectueux dès la première utilisation.C'est de l'import UK mais c'est le même produit que chez nous. J'ai acheté celui ci car l'autre était en rupture.

Various reviews led me to the Sony cassette adaptor for the iPod and I was not dissappointed. I had a long road trip with my 4 year old daughter to Oregon (from LA) and it helped make the long drive interesting and entertaining. I imported all of my 200-plus CDs as well as a bunch of hers (Disney,etc) - so it was all in one place. Being able to access your entire CD collection in you car is amazing.The Sony adaptor is an extremely simple and effective tool. And very affordable. When I first received it I tried it in the car in the garage with the motor off. I can tell you I was not completely impressed in this environment as the sound is clearly not digital quality. But when on the road, with the usual road noise, it sounds as good as any CD. I was pleasantly surprised. The garage test was not an accurate or fair test environment for this product.I considered one of the FM tuner adaptors but this would have been very limiting during the mountain drives as I'm sure I would have not been able to receive a signal. And I would have been having to tune in different stations as I passed through the myriad of towns I passed through - a definite inconvenience. Luckily my car has both the cassette player as well as a CD player.This is a GREAT product for those not lucky enough to have a new car with iPod or MP3 capability built in.
