Hi all, Had my L1 for a wk now for burning and comparing, i've compared with Denon ANC800, Shure 940 and Beats Pro. For introduction i am very impress with the built and quality of the L1 and the box display it very nicely. I won't go into details on sound quality as many members here already discussed and i am not pro in audio and sound. So, comparison on basic things like Isolation, Leakage, comfort, sound, built and design.
Isolation
L1 isolation is quite good compare to other semi open (Which i do not own any) but as i compared with full closed headphone, some are not better than this semi open. You can really control the volume for the surrounding isolation, i used my Iphone 3GS as i am on 80% volume, i barely hear my surrounding. So, if in noisy environment i will probably up to 90%.
L1 isolation considered good as a semi open.
Leakage
Lots of people concerned about leakage including myself. Comparing with other headphone i owned, i found Shure 940 is best leakage proof. L1 still have leakage so i prefer if use it in quite places like library should down volume below 50% on Iphone. Beats Pro have better leakage proof than the L1.
Comfort
This is one of the thing excite me. Comfort of L1 is very very impressive provided its metal built and weight. However, it is very comfy as i rank for myself quite high and i can wear it many hours. Clamping force and headband is just right and the ear cushion has enough space for my ear (In depth and covered whole ear). Denon 800 is my best for comfy, L1 come second, Shure 940 3, beats Pro 4 (Very hard clamping force, maximum 2 hrs wear for me).
Sound
L1 sound covered everything from High, Mids and Low. Not too much of all and nice combinations. I like it very much as i do not like so much bass which will blow the high and mids away, but this has just the right amount for me. Beats Pro has the most bass but details not quite good as the L1.
L1 > Beats Pro > Denon 800 > Shure 940. (In my opinion, as i am not studio geek but only listen to music when i travel.)
Built and Design
L1 - Built is very impressive, leather headband and aluminium body, cable is tangle free and very high quality materials. Microphone on the cable is the best out of most headphone with microphone cable. I've used a lot of talking on the phone and the quality can be heard very clearly. (Also my surrounding noise too, better not to use it in public transport)
L1 built and design is better than Denon 800, Shure 940 and Beats Pro.
Conclusion:
I like the L1 very much and now it is my most used headphone for all purposes. If on the plane i would use noise cancellation Denon ANC 800 as it have NC and better leakage proof. Other than that, i am very happy with L1 and its quality philips has included in this Fidelio headphone.
