About the Sennheiser HD 4.20s

Sennheiser sound — at the right price

I think the Sennheiser HD 4.20s offer some of the best value in over-ear headphones. For less than $100, you get a set of slick, no-nonsense 'phones with real pedigree. Sennheiser has been one of (if not the) leading name in headphones for decades. I got a brief listening session and can tell you: if good sound is what you're looking for in headphones, you can't do much better at this price.

Nice features, too   

The Sennheiser HD 4.20s headphones are comfortably padded and lightweight. They also fold up so you can easily take them from place to place. Or you can just keep them connected to your phone on-the-go. The handy in-line one-button remote/mic gives you control over music and calls.

Sennheiser HD 4.20s for the win!

I work from home for gaming company and we do everything over skype or discord and I use these headphones for everything! They are great! I hated having a big microphone sticking out of my headset and I don't like the earbuds that come with cell phones. I've always enjoyed over-the-ear headsets. These are exceptionally awesome. They sound amazing and the price is as equally amazing.

Good for Price - Over Ear Cushion Falls Off

Crutchfield customer from West Orange, NJ on 12/28/2017

These are actually a very good headphone for the money. My only complaint is that the over ear cushions come off very easily and are kind of difficult to put back on.

Great sound, very comfortable fit for over-the-ear headphones. I had to hunt for a case to put it in though. Also, still not sure if I'll need an adaptor (not provided) for flights.

Clear and strong sound

Hank from Chicago, IL on 2/6/2017

Verified customer (What's this?)
Verified employee purchase (What's this?)

I am a product loyalist and the Sennheiser product has never let me down. For the price, this model provided me with good clear sound. The bass was clear throughout all the various music genres I listen to. The highs were just clear enough not to distort any midrange. They look durable and fold up with ease. I have not used the phone volume feature as of yet. The comfort is excellent. It would be nice if the included a fabric type carrying case.

Pros: Comfort Bass Price

Cons: None

The remote has additional functionality (fast forward/reverse, and skipping to the previous track) for iPhone, iPad, and iPod touch. They have a standard analog 3.5mm minijack connector so, there is no computer-specific capabilities.

Hey Freddy. My ear buds work with my mac pro, but I have not tried the headphones. My headphones are receive only, so I can't reply to your second question. I love the unit and I am very satisfied with it. I use it 99.9 % of the time with the LG tv. Rick
