Lawton Audio: Headphones Perfected

You can think of what we do at Lawton Audio as being akin to taking a superb loudspeaker driver array from a mass-produced floor-stander, then totally re-wiring and re-housing it in a superior custom built cabinet. The net benefits for your headphones are just as dramatic and easily appreciable by any listener. We don’t upgrade these phones because we want to re-shape them to our tastes. We simply enable that superb transducer to perform at its best, without the considerations or constraints of a mass-market manufacturer.

We know these phones like no one else. We’ve been upgrading Fostex-made phones since 2007 with a series of innovative and acclaimed mods developed specifically for them.

Why Upgrade Fostex Headphones?

To make a great pair of custom headphones, you need to start with a great base unit, and for many people, nothing offers a more satisfying musical package than the Fostex-made units, TH-X00, TH-600, TH-610 & TH-900 (& the Fostex-made Creative Labs E-MU!). These phones achieve the rare feat of managing to sound totally musical, engaging and lively while remaining accurate and natural-sounding. They are very popular with musicians, especially those that like to record themselves; producers and artists appreciate a highly musical transducer that still sounds real and true to the source. Last but not least, the Fostex has a thumpin’ dynamic-style driver that really hits the spot with fans of Rock/Pop/Electronic or any rhythm-based music. Micro-detail plus big dynamics; these are the audiophile grade phones that didn’t forget to bring the fun!

Attention: FOSTEX Fans, We Specialize in Upgrades for Bio-Cellulose Beauties

Never visited Lawton Audio? We know these phones like no one else. We’ve been upgrading Fostex-made bio-cellulose phones since 2007, with a series of innovative and acclaimed mods developed specifically for them. Like you, we love these phones; heck, we built our company around them!  No one has handled more of these phones than us.

Denon Fans: Meet Your New Favorite Headphone

If you were a past customer who loved the Denon sound and what our Authentic Upgrades brought to them, the new Fostex are for you! The TH-X00, TH-600 & TH-900 are the best platforms yet for our 3 Levels of Upgrades. Plus our Upgrades are all-new and developed specifically for these majestic phones.

As we headphone fans have known for a long time, Fostex was the actual manufacturer for the classic Denon line of bio-cellulose cans. We upgraded them for many years, they are now sadly discontinued. Now the original manufacturer has more than met that challenge with the terrific TH-X00, TH-600 & TH-900. You can see the new Fostex phones bear a striking resemblance to the old Denons, and that carries over to their familiar sound as well. The Fostex units have everything you loved and more, they are the next-generation version of your favorite phones.

Our New Upgrades Fit Your Classic Denon, Too!

Don’t despair classic Denon fans, all of our next-generation mods for Fostex also fit your trusty AH-D5000 or AH-D7000 as well. Yes indeed, our latest Upgrades make your old Denon sound better than ever; so shop our site, the pricing and installation you see is the same for your phones.

Attention: Musicians!

Now you can listen to the same wood you like to play. Our Custom Wood Chambers are a highly musical addition for these phones; made from your choice of over 25 of the world’s best natural ToneWoods. You know which wood produces the sound you like; now you can select your favorite flavor for your Fostex. Sound good?

Professional Installation Or Do-It-Yourself

Many of our Upgrades can be self-installed, saving on labor and shipping costs. With only minimal tools and a moderate level of experience, you too can . We have easy to install Kits for the DIY-er, and a professional installation service. We happliy serve customers from all over the world.
